glibc: Migrate eglibc 2.19 -> glibc 2.20
- This is a big swoop change where we switch to using glibc
- option-groups are forward ported
- cross-localedef is extracted out from eglibc and hosted
at github.com/kraj/localedef, its used for cross-localedef
recipe
- Other non ported patches from eglibc are forward ported
ppc8xx cache line workaround
SH fpcr values
dynamic resolver
installing PIC archives is there but is not applied
libc header bootstrap
- Delete eglibc recipes we moved back to using glibc now
- Fix ppc/e500 build
- Fix crypt module build when options are used
- Fix fnmatch build when options OPTION_EGLIBC_LOCALE_CODE is unset
HAVE_MBSTATE_T and HAVE_MBSRTOWCS should be defined conditionally
based upon OPTION_EGLIBC_LOCALE_CODE being set/unset
- Move the ports/ patches to relevant files now that ports is gone

When we run it, + it dies with a SIGSEGV before reaching main(). + + Libust.so depends on liburcu-bp.so from the usermode-rcu package. + Although libust.so is not prelinked, liburcu-bp.so IS prelinked; this + is critical. + + Libust.so uses a TLS / __thread variable that is defined in liburcu- + bp.so. There are special ARM-specific relocation types that allow two + shared libraries to share thread-specific data. This is critical too. + + One more critical issue: although liburcu-bp.so is prelinked, we can't + load it at its prelinked address, because we also link against + librt.so, and librt.so uses that address. + + The dynamic linker is forced to relink liburcu-bp.so at a different + address. In the course of relinking, it processes the special ARM + relocation record mentioned above. The prelinker has already filled + in the information, which is a short offset into a table of thread- + specific data that is allocated per-thread for each library that uses + TLS. Because the normal behavior of a relocation is to add the symbol + value to an addend stored at the address being relocated, we end up + adding the short offset to itself, doubling it. + + Now we have an awkward situation. The libust.so library doesn't know + about the addend, so its TLS data for this element is correct. The + liburcu-bp.so library has a different offset for the element. When we + go to initialize the element for the first time in liburcu-bp.so, we + write the address of the result at the doubled (broken) offset. + Later, when we refer to the address from libust.so, we check the value + at the correct offset, but it's NULL, so we eat hot SIGSEGV. + +Upstream-Status: Pending + +Signed-off-by: Andrei Dinu <andrei.adrianx.dinu@intel.com> +--- + .../libc/ports/sysdeps/arm/dl-machine.h | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +ndex 8d905e8..dcfa71e 100644 +Index: git/sysdeps/arm/dl-machine.h +=================================================================== +--- git.orig/sysdeps/arm/dl-machine.h 2014-08-27 05:30:47.748070587 +0000 ++++ git/sysdeps/arm/dl-machine.h 2014-08-27 05:30:47.740070587 +0000 +@@ -495,7 +495,7 @@ + + case R_ARM_TLS_DTPOFF32: + if (sym != NULL) +- *reloc_addr += sym->st_value; ++ *reloc_addr = sym->st_value; + break; + + case R_ARM_TLS_TPOFF32: diff --git a/meta/recipes-core/glibc/glibc/0001-eglibc-run-libm-err-tab.pl-with-specific-dirs-in-S.patch b/meta/recipes-core/glibc/glibc/0001-eglibc-run-libm-err-tab.pl-with-specific-dirs-in-S.patch new file mode 100644 index 0000000000..f341282ffb --- /dev/null +++ b/meta/recipes-core/glibc/glibc/0001-eglibc-run-libm-err-tab.pl-with-specific-dirs-in-S.patch @@ -0,0 +1,33 @@ +From 713d822908d1b2ae8403af7f9375c7054ed3dd49 Mon Sep 17 00:00:00 2001 +From: Ting Liu <b28495@freescale.com> +Date: Wed, 19 Dec 2012 04:39:57 -0600 +Subject: [PATCH] eglibc: run libm-err-tab.pl with specific dirs in ${S} + +libm-err-tab.pl will parse all the files named "libm-test-ulps" +in the given dir recursively.

Unfortunately, the ++process of cross-compiling the GNU C library is quite a bit more ++involved: ++ ++1) Build a cross-compiler, with certain facilities disabled. ++ ++2) Configure the C library using the compiler you built in step 1). ++ Build a few of the C run-time object files, but not the rest of the ++ library.

EGLIBC includes features and bug fixes to the stock ++GNU C library that simplify this process, but the fundamental ++interdependency stands. ++ ++In this document, we explain how to cross-compile an EGLIBC/GCC pair ++from source. Our intended audience is developers who are already ++familiar with the GNU toolchain and comfortable working with ++cross-development tools. While we do present a worked example to ++accompany the explanation, for clarity's sake we do not cover many of ++the options available to cross-toolchain users. ++ ++ ++Preparation ++ ++EGLIBC requires recent versions of the GNU binutils, GCC, and the ++Linux kernel. The web page <http://www.eglibc.org/prerequisites> ++documents the current requirements, and lists patches needed for ++certain target architectures. As of this writing, these build ++instructions have been tested with binutils 2.22.51, GCC 4.6.2, ++and Linux 3.1. ++ ++First, let's set some variables, to simplify later commands. We'll ++build EGLIBC and GCC for an ARM target, known to the Linux kernel ++as 'arm', and we'll do the build on an Intel x86_64 Linux box: ++ ++ $ build=x86_64-pc-linux-gnu ++ $ host=$build ++ $ target=arm-none-linux-gnueabi ++ $ linux_arch=arm ++ ++We're using the aforementioned versions of Binutils, GCC, and Linux: ++ ++ $ binutilsv=binutils-2.22.51 ++ $ gccv=gcc-4.6.2 ++ $ linuxv=linux-3.1 ++ ++We're carrying out the entire process under '~/cross-build', which ++contains unpacked source trees for binutils, gcc, and linux kernel, ++along with EGLIBC svn trunk (which can be checked-out with ++'svn co http://www.eglibc.org/svn/trunk eglibc'): ++ ++ $ top=$HOME/cross-build/$target ++ $ src=$HOME/cross-build/src ++ $ ls $src ++ binutils-2.22.51 eglibc gcc-4.6.2 linux-3.1 ++ ++We're going to place our build directories in a subdirectory 'obj', ++we'll install the cross-development toolchain in 'tools', and we'll ++place our sysroot (containing files to be installed on the target ++system) in 'sysroot': ++ ++ $ obj=$top/obj ++ $ tools=$top/tools ++ $ sysroot=$top/sysroot ++ ++ ++Binutils ++ ++Configuring and building binutils for the target is straightforward: ++ ++ $ mkdir -p $obj/binutils ++ $ cd $obj/binutils ++ $ $src/$binutilsv/configure \ ++ > --target=$target \ ++ > --prefix=$tools \ ++ > --with-sysroot=$sysroot ++ $ make ++ $ make install ++ ++ ++The First GCC ++ ++For our work, we need a cross-compiler targeting an ARM Linux ++system. However, that configuration includes the shared library ++'libgcc_s.so', which is compiled against the EGLIBC headers (which we ++haven't installed yet) and linked against 'libc.so' (which we haven't ++built yet). ++ ++Fortunately, there are configuration options for GCC which tell it not ++to build 'libgcc_s.so'. The '--without-headers' option is supposed to ++take care of this, but its implementation is incomplete, so you must ++also configure with the '--with-newlib' option. While '--with-newlib' ++appears to mean "Use the Newlib C library", its effect is to tell the ++GCC build machinery, "Don't assume there is a C library available." ++ ++We also need to disable some of the libraries that would normally be ++built along with GCC, and specify that only the compiler for the C ++language is needed. ++ ++So, we create a build directory, configure, make, and install. ++ ++ $ mkdir -p $obj/gcc1 ++ $ cd $obj/gcc1 ++ $ $src/$gccv/configure \ ++ > --target=$target \ ++ > --prefix=$tools \ ++ > --without-headers --with-newlib \ ++ > --disable-shared --disable-threads --disable-libssp \ ++ > --disable-libgomp --disable-libmudflap --disable-libquadmath \ ++ > --disable-decimal-float --disable-libffi \ ++ > --enable-languages=c ++ $ PATH=$tools/bin:$PATH make ++ $ PATH=$tools/bin:$PATH make install ++ ++ ++Linux Kernel Headers ++ ++To configure EGLIBC, we also need Linux kernel headers in place. ++Fortunately, the Linux makefiles have a target that installs them for ++us. Since the process does modify the source tree a bit, we make a ++copy first: ++ ++ $ cp -r $src/$linuxv $obj/linux ++ $ cd $obj/linux ++ ++Now we're ready to install the headers into the sysroot: ++ ++ $ PATH=$tools/bin:$PATH \ ++ > make headers_install \ ++ > ARCH=$linux_arch CROSS_COMPILE=$target- \ ++ > INSTALL_HDR_PATH=$sysroot/usr ++ ++ ++EGLIBC Headers and Preliminary Objects ++ ++Using the cross-compiler we've just built, we can now configure EGLIBC ++well enough to install the headers and build the object files that the ++full cross-compiler will need: ++ ++ $ mkdir -p $obj/eglibc-headers ++ $ cd $obj/eglibc-headers ++ $ BUILD_CC=gcc \ ++ > CC=$tools/bin/$target-gcc \ ++ > CXX=$tools/bin/$target-g++ \ ++ > AR=$tools/bin/$target-ar \ ++ > RANLIB=$tools/bin/$target-ranlib \ ++ > $src/eglibc/libc/configure \ ++ > --prefix=/usr \ ++ > --with-headers=$sysroot/usr/include \ ++ > --build=$build \ ++ > --host=$target \ ++ > --disable-profile --without-gd --without-cvs \ ++ > --enable-add-ons=nptl,libidn,../ports ++ ++The option '--prefix=/usr' may look strange, but you should never ++configure EGLIBC with a prefix other than '/usr': in various places, ++EGLIBC's build system checks whether the prefix is '/usr', and does ++special handling only if that is the case. Unless you use this ++prefix, you will get a sysroot that does not use the standard Linux ++directory layouts and cannot be used as a basis for the root ++filesystem on your target system compatibly with normal GLIBC ++installations. ++ ++The '--with-headers' option tells EGLIBC where the Linux headers have ++been installed. ++ ++The '--enable-add-ons=nptl,libidn,../ports' option tells EGLIBC to look ++for the listed glibc add-ons. Most notably the ports add-on (located ++just above the libc sources in the EGLIBC svn tree) is required to ++support ARM targets. ++ ++We can now use the 'install-headers' makefile target to install the ++headers: ++ ++ $ make install-headers install_root=$sysroot \ ++ > install-bootstrap-headers=yes ++ ++The 'install_root' variable indicates where the files should actually ++be installed; its value is treated as the parent of the '--prefix' ++directory we passed to the configure script, so the headers will go in ++'$sysroot/usr/include'. The 'install-bootstrap-headers' variable ++requests special handling for certain tricky header files. ++ ++Next, there are a few object files needed to link shared libraries, ++which we build and install by hand: ++ ++ $ mkdir -p $sysroot/usr/lib ++ $ make csu/subdir_lib ++ $ cp csu/crt1.o csu/crti.o csu/crtn.o $sysroot/usr/lib ++ ++Finally, 'libgcc_s.so' requires a 'libc.so' to link against. However, ++since we will never actually execute its code, it doesn't matter what ++it contains. So, treating '/dev/null' as a C source file, we produce ++a dummy 'libc.so' in one step: ++ ++ $ $tools/bin/$target-gcc -nostdlib -nostartfiles -shared -x c /dev/null \ ++ > -o $sysroot/usr/lib/libc.so ++ ++ ++The Second GCC ++ ++With the EGLIBC headers and selected object files installed, we can ++now build a GCC that is capable of compiling EGLIBC.

These tools can be re-used by EGLIBC for its own 'make ++*config' support, which will create 'option-groups.config' for you. ++But first make sure those tools have been built by running some ++dummy 'make *config' calls in the kernel directory: ++ ++ $ cd $obj/linux ++ $ PATH=$tools/bin:$PATH make config \ ++ > ARCH=$linux_arch CROSS_COMPILE=$target- \ ++ $ PATH=$tools/bin:$PATH make menuconfig \ ++ > ARCH=$linux_arch CROSS_COMPILE=$target- \ ++ ++Now we can configure and build the full EGLIBC: ++ ++ $ cd $obj/eglibc ++ $ PATH=$tools/bin:$PATH make defconfig ++ $ PATH=$tools/bin:$PATH make menuconfig ++ $ PATH=$tools/bin:$PATH make ++ $ PATH=$tools/bin:$PATH make install install_root=$sysroot ++ ++At this point, we have a complete EGLIBC installation in '$sysroot', ++with header files, library files, and most of the C runtime startup ++files in place. ++ ++ ++The Third GCC ++ ++Finally, we recompile GCC against this full installation, enabling ++whatever languages and libraries we would like to use: ++ ++ $ mkdir -p $obj/gcc3 ++ $ cd $obj/gcc3 ++ $ $src/$gccv/configure \ ++ > --target=$target \ ++ > --prefix=$tools \ ++ > --with-sysroot=$sysroot \ ++ > --enable-__cxa_atexit \ ++ > --disable-libssp --disable-libgomp --disable-libmudflap \ ++ > --enable-languages=c,c++ ++ $ PATH=$tools/bin:$PATH make ++ $ PATH=$tools/bin:$PATH make install ++ ++The '--enable-__cxa_atexit' option tells GCC what sort of C++ ++destructor support to expect from the C library; it's required with ++EGLIBC. ++ ++And since GCC's installation process isn't designed to help construct ++sysroot trees, we must manually copy certain libraries into place in ++the sysroot. ++ ++ $ cp -d $tools/$target/lib/libgcc_s.so* $sysroot/lib ++ $ cp -d $tools/$target/lib/libstdc++.so* $sysroot/usr/lib ++ ++ ++Trying Things Out ++ ++At this point, '$tools' contains a cross toolchain ready to use ++the EGLIBC installation in '$sysroot': ++ ++ $ cat > hello.c <<EOF ++ > #include <stdio.h> ++ > int ++ > main (int argc, char **argv) ++ > { ++ > puts ("Hello, world!"); ++ > return 0; ++ > } ++ > EOF ++ $ $tools/bin/$target-gcc -Wall hello.c -o hello ++ $ cat > c++-hello.cc <<EOF ++ > #include <iostream> ++ > int ++ > main (int argc, char **argv) ++ > { ++ > std::cout << "Hello, C++ world!" << std::endl; ++ > return 0; ++ > } ++ > EOF ++ $ $tools/bin/$target-g++ -Wall c++-hello.cc -o c++-hello ++ ++ ++We can use 'readelf' to verify that these are indeed executables for ++our target, using our dynamic linker: ++ ++ $ $tools/bin/$target-readelf -hl hello ++ ELF Header: ++ ... ++ Type: EXEC (Executable file) ++ Machine: ARM ++ ++ ... ++ Program Headers: ++ Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align ++ PHDR 0x000034 0x10000034 0x10000034 0x00100 0x00100 R E 0x4 ++ INTERP 0x000134 0x00008134 0x00008134 0x00013 0x00013 R 0x1 ++ [Requesting program interpreter: /lib/ld-linux.so.3] ++ LOAD 0x000000 0x00008000 0x00008000 0x0042c 0x0042c R E 0x8000 ++ ... ++ ++Looking at the dynamic section of the installed 'libgcc_s.so', we see ++that the 'NEEDED' entry for the C library does include the '.6' ++suffix, indicating that was linked against our fully build EGLIBC, and ++not our dummy 'libc.so': ++ ++ $ $tools/bin/$target-readelf -d $sysroot/lib/libgcc_s.so.1 ++ Dynamic section at offset 0x1083c contains 24 entries: ++ Tag Type Name/Value ++ 0x00000001 (NEEDED) Shared library: [libc.so.6] ++ 0x0000000e (SONAME) Library soname: [libgcc_s.so.1] ++ ... ++ ++ ++And on the target machine, we can run our programs: ++ ++ $ $sysroot/lib/ld.so.1 --library-path $sysroot/lib:$sysroot/usr/lib \ ++ > ./hello ++ Hello, world! ++ $ $sysroot/lib/ld.so.1 --library-path $sysroot/lib:$sysroot/usr/lib \ ++ > ./c++-hello ++ Hello, C++ world! +Index: git/EGLIBC.cross-testing +=================================================================== +--- /dev/null 1970-01-01 00:00:00.000000000 +0000 ++++ git/EGLIBC.cross-testing 2014-08-27 07:24:41.532070587 +0000 +@@ -0,0 +1,205 @@ ++ -*- mode: text -*- ++ ++ Cross-Testing With EGLIBC ++ Jim Blandy <jimb@codesourcery.com> ++ ++ ++Introduction ++ ++Developers writing software for embedded systems often use a desktop ++or other similarly capable computer for development, but need to run ++tests on the embedded system, or perhaps on a simulator. When ++configured for cross-compilation, the stock GNU C library simply ++disables running tests altogether: the command 'make tests' builds ++test programs, but does not run them. EGLIBC, however, provides ++facilities for compiling tests and generating data files on the build ++system, but running the test programs themselves on a remote system or ++simulator. ++ ++ ++Test environment requirements ++ ++The test environment must meet certain conditions for EGLIBC's ++cross-testing facilities to work: ++ ++- Shared filesystems. The 'build' system, on which you configure and ++ compile EGLIBC, and the 'host' system, on which you intend to run ++ EGLIBC, must share a filesystem containing the EGLIBC build and ++ source trees. Files must appear at the same paths on both systems. ++ ++- Remote-shell like invocation. There must be a way to run a program ++ on the host system from the build system, passing it properly quoted ++ command-line arguments, setting environment variables, and ++ inheriting the caller's standard input and output. ++ ++ ++Usage ++ ++To use EGLIBC's cross-testing support, provide values for the ++following Make variables when you invoke 'make': ++ ++- cross-test-wrapper ++ ++ This should be the name of the cross-testing wrapper command, along ++ with any arguments. ++ ++- cross-localedef ++ ++ This should be the name of a cross-capable localedef program, like ++ that included in the EGLIBC 'localedef' module, along with any ++ arguments needed. ++ ++These are each explained in detail below. ++ ++ ++The Cross-Testing Wrapper ++ ++To run test programs reliably, the stock GNU C library takes care to ++ensure that test programs use the newly compiled dynamic linker and ++shared libraries, and never the host system's installed libraries. To ++accomplish this, it runs the tests by explicitly invoking the dynamic ++linker from the build tree, passing it a list of build tree ++directories to search for shared libraries, followed by the name of ++the executable to run and its arguments. ++ ++For example, where one might normally run a test program like this: ++ ++ $ ./tst-foo arg1 arg2 ++ ++the GNU C library might run that program like this: ++ ++ $ $objdir/elf/ld-linux.so.3 --library-path $objdir \ ++ ./tst-foo arg1 arg2 ++ ++(where $objdir is the path to the top of the build tree, and the ++trailing backslash indicates a continuation of the command). In other ++words, each test program invocation is 'wrapped up' inside an explicit ++invocation of the dynamic linker, which must itself execute the test ++program, having loaded shared libraries from the appropriate ++directories. ++ ++To support cross-testing, EGLIBC allows the developer to optionally ++set the 'cross-test-wrapper' Make variable to another wrapper command, ++to which it passes the entire dynamic linker invocation shown above as ++arguments. For example, if the developer supplies a wrapper of ++'my-wrapper hostname', then EGLIBC would run the test above as ++follows: ++ ++ $ my-wrapper hostname \ ++ $objdir/elf/ld-linux.so.3 --library-path $objdir \ ++ ./tst-foo arg1 arg2 ++ ++The 'my-wrapper' command is responsible for executing the command ++given on the host system. ++ ++Since tests are run in varying directories, the wrapper should either ++be in your command search path, or 'cross-test-wrapper' should give an ++absolute path for the wrapper. ++ ++The wrapper must meet several requirements: ++ ++- It must preserve the current directory. As explained above, the ++ build directory tree must be visible on both the build and host ++ systems, at the same path. The test wrapper must ensure that the ++ current directory it inherits is also inherited by the dynamic ++ linker (and thus the test program itself). ++ ++- It must preserve environment variables' values. Many EGLIBC tests ++ set environment variables for test runs; in native testing, it ++ invokes programs like this: ++ ++ $ GCONV_PATH=$objdir/iconvdata \ ++ $objdir/elf/ld-linux.so.3 --library-path $objdir \ ++ ./tst-foo arg1 arg2 ++ ++ With the cross-testing wrapper, that invocation becomes: ++ ++ $ GCONV_PATH=$objdir/iconvdata \ ++ my-wrapper hostname \ ++ $objdir/elf/ld-linux.so.3 --library-path $objdir \ ++ ./tst-foo arg1 arg2 ++ ++ Here, 'my-wrapper' must ensure that the value it sees for ++ 'GCONV_PATH' will be seen by the dynamic linker, and thus 'tst-foo' ++ itself. (The wrapper supplied with GLIBC simply preserves the ++ values of *all* enviroment variables, with a fixed set of ++ exceptions.) ++ ++ If your wrapper is a shell script, take care to correctly propagate ++ environment variables whose values contain spaces and shell ++ metacharacters. ++ ++- It must pass the command's arguments, unmodified. The arguments ++ seen by the test program should be exactly those seen by the wrapper ++ (after whatever arguments are given to the wrapper itself). The ++ EGLIBC test framework performs all needed shell word splitting and ++ expansion (wildcard expansion, parameter substitution, and so on) ++ before invoking the wrapper; further expansion may break the tests. ++ ++ ++The 'cross-test-ssh.sh' script ++ ++If you want to use 'ssh' (or something sufficiently similar) to run ++test programs on your host system, EGLIBC includes a shell script, ++'scripts/cross-test-ssh.sh', which you can use as your wrapper ++command. This script takes care of setting the test command's current ++directory, propagating environment variable values, and carrying ++command-line arguments, all across an 'ssh' connection. You may even ++supply an alternative to 'ssh' on the command line, if needed. ++ ++For more details, pass 'cross-test-ssh.sh' the '--help' option. ++ ++ ++The Cross-Compiling Locale Definition Command ++ ++Some EGLIBC tests rely on locales generated especially for the test ++process. In a native configuration, these tests simply run the ++'localedef' command built by the normal EGLIBC build process, ++'locale/localedef', to process and install their locales. However, in ++a cross-compiling configuration, this 'localedef' is built for the ++host system, not the build system, and since it requires quite a bit ++of memory to run (we have seen it fail on systems with 64MiB of ++memory), it may not be practical to run it on the host system. ++ ++If set, EGLIBC uses the 'cross-localedef' Make variable as the command ++to run on the build system to process and install locales. The ++localedef program built from the EGLIBC 'localedef' module is ++suitable. ++ ++The value of 'cross-localedef' may also include command-line arguments ++to be passed to the program; if you are using EGLIBC's 'localedef', ++you may include endianness and 'uint32_t' alignment arguments here. ++ ++ ++Example ++ ++In developing EGLIBC's cross-testing facility, we invoked 'make' with ++the following script: ++ ++ #!/bin/sh ++ ++ srcdir=... ++ test_hostname=... ++ localedefdir=... ++ cross_gxx=...-g++ ++ ++ wrapper="$srcdir/scripts/cross-test-ssh.sh $test_hostname" ++ localedef="$localedefdir/localedef --little-endian --uint32-align=4" ++ ++ make cross-test-wrapper="$wrapper" \ ++ cross-localedef="$localedef" \ ++ CXX="$cross_gxx" \ ++ "$@" ++ ++ ++Other Cross-Testing Concerns ++ ++Here are notes on some other issues which you may encounter in running ++the EGLIBC tests in a cross-compiling environment: ++ ++- Some tests require a C++ cross-compiler; you should set the 'CXX' ++ Make variable to the name of an appropriate cross-compiler. ++ ++- Some tests require access to libstdc++.so.6 and libgcc_s.so.1; we ++ simply place copies of these libraries in the top EGLIBC build ++ directory. diff --git a/meta/recipes-core/glibc/glibc/etc/ld.so.conf b/meta/recipes-core/glibc/glibc/etc/ld.so.conf new file mode 100644 index 0000000000..e69de29bb2 --- /dev/null +++ b/meta/recipes-core/glibc/glibc/etc/ld.so.conf diff --git a/meta/recipes-core/glibc/glibc/fix-tibetian-locales.patch b/meta/recipes-core/glibc/glibc/fix-tibetian-locales.patch new file mode 100644 index 0000000000..9ab9fdcf12 --- /dev/null +++ b/meta/recipes-core/glibc/glibc/fix-tibetian-locales.patch @@ -0,0 +1,38 @@ +cross localedef fails to compile these locales because name_fmt field is empty +It is not acceptable for cross localedef and it errors out + +LC_NAME: field `name_fmt' not defined + +We therefore give a dummy string to the format, the real fix needs some native +tibetian person to define proper name_fmt + +Upstream-Status: Pending + +Signed-off-by: Khem Raj <raj.khem@gmail.com> + +Index: git/localedata/locales/bo_CN +=================================================================== +--- git.orig/localedata/locales/bo_CN 2014-08-29 10:35:22.464070587 -0700 ++++ git/localedata/locales/bo_CN 2014-08-29 10:35:22.456070587 -0700 +@@ -146,7 +146,7 @@ + LC_NAME + % FIXME + +-name_fmt "" ++name_fmt "FIXME" + % name_gen "FIXME" + % name_miss "FIXME" + % name_mr "FIXME" +Index: git/localedata/locales/bo_IN +=================================================================== +--- git.orig/localedata/locales/bo_IN 2014-08-29 10:35:22.464070587 -0700 ++++ git/localedata/locales/bo_IN 2014-08-29 10:35:22.456070587 -0700 +@@ -71,7 +71,7 @@ + + LC_NAME + % FIXME +-name_fmt "" ++name_fmt "FIXME" + % name_gen "FIXME" + % name_miss "FIXME" + % name_mr "FIXME" diff --git a/meta/recipes-core/glibc/glibc/fix_am_rootsbindir.patch b/meta/recipes-core/glibc/glibc/fix_am_rootsbindir.patch new file mode 100644 index 0000000000..668e8bf678 --- /dev/null +++ b/meta/recipes-core/glibc/glibc/fix_am_rootsbindir.patch @@ -0,0 +1,29 @@ +sysdeps/gnu/configure.ac: handle correctly $libc_cv_rootsbindir + +Upstream-Status:Pending +Signed-off-by: Matthieu Crapet <Matthieu.Crapet@ingenico.com> + +Index: git/sysdeps/gnu/configure +=================================================================== +--- git.orig/sysdeps/gnu/configure 2014-08-27 07:24:38.572070587 +0000 ++++ git/sysdeps/gnu/configure 2014-08-27 07:24:41.308070587 +0000 +@@ -32,6 +32,6 @@ + else + libc_cv_localstatedir=$localstatedir + fi +- libc_cv_rootsbindir=/sbin ++ test -n "$libc_cv_rootsbindir" || libc_cv_rootsbindir=/sbin + ;; + esac +Index: git/sysdeps/gnu/configure.ac +=================================================================== +--- git.orig/sysdeps/gnu/configure.ac 2014-08-27 07:24:38.572070587 +0000 ++++ git/sysdeps/gnu/configure.ac 2014-08-27 07:24:41.308070587 +0000 +@@ -21,6 +21,6 @@ + else + libc_cv_localstatedir=$localstatedir + fi +- libc_cv_rootsbindir=/sbin ++ test -n "$libc_cv_rootsbindir" || libc_cv_rootsbindir=/sbin + ;; + esac diff --git a/meta/recipes-core/glibc/glibc/fsl-ppc-no-fsqrt.patch b/meta/recipes-core/glibc/glibc/fsl-ppc-no-fsqrt.patch new file mode 100644 index 0000000000..f88eaf444e --- /dev/null +++ b/meta/recipes-core/glibc/glibc/fsl-ppc-no-fsqrt.patch @@ -0,0 +1,100 @@ +Create e5500 specific math_private.h and let it include when compiling for e5500/64bit core +We prefefine __CPU_HAS_FSQRT to 0 and then in general ppc64 math_private.h we check if its +already defined before redefining it.

Its website boasts that "nearly all known and ++useful functions from any other C library are available." This ++exhaustive approach has been one of GLIBC's strengths on desktop and ++server systems, but it has also given GLIBC a large footprint, both in ++memory and on disk, making it a challenge to use in embedded systems ++with limited resources. ++ ++The Embedded GNU C library (EGLIBC) is a variant of the GNU C library ++designed to work well on embedded systems. In particular, EGLIBC's ++component configuration system allows embedded developers to build ++customized versions of the library that include only the features ++their application uses, reducing its space requirements. ++ ++EGLIBC's component configuration system categorizes the library's ++functions into "option groups", and allows you to include or exclude ++option groups individually. Some option groups depend on others; ++EGLIBC tracks these relationships, and ensures that the selected ++configuration yields a functioning library. ++ ++ ++Consistent and Predictable Behavior ++ ++A flexible configuration system is a mixed blessing: if the options ++offered are poorly designed, it can be hard to see which choices will ++have the desired effects, and choices with obscure consequences can ++make debugging difficult. EGLIBC's configuration follows some general ++principles to reduce these risks: ++ ++- EGLIBC has a single default configuration for each target ++ architecture. ++ ++- In the default configuration, all option groups are enabled, and ++ EGLIBC is upwardly API- and ABI-compatible with GLIBC. ++ ++- As much as possible, configurations only affect what functions are ++ present, not how they behave. If the system works with an option ++ group disabled, it will still work with it enabled. ++ ++- As much as possible, configurations only select option groups --- ++ they do not describe characteristics of the target architecture. ++ ++These rules mean that you have a simple debugging strategy available ++if you suspect that your EGLIBC configuration might be the source of a ++problem: fall back to the default configuration, re-test, and then ++disable option groups one by one, until the problem reappears. ++ ++ ++The Option Groups ++ ++To see the current full list of implemented option groups, refer to the ++file 'option-groups.def' at the top of the source tree, or run ++'make menuconfig' from the top-level build directory. ++ ++The POSIX.1-2001 specification includes a suggested partition of all ++the functions in the POSIX C API into option groups: math functions ++like 'sin' and 'cos'; networking functions like 'socket' and ++'connect'; and so on. EGLIBC could use this partitioning as the basis ++for future option groups. ++ ++ ++Implementation ++ ++The EGLIBC component configuration system resembles the approach used ++by the Linux kernel to select device drivers, network protocols, and ++other features. A file named 'option-groups.config' in the top-level ++build directory contains assignments to Make variables, each of which ++enables or disables a particular option group. If the variable's ++value is set to 'y', then the option group is enabled; if it set to ++anything else, the option group is omitted. The file ++'option-groups.defaults', at the top of the source tree, establishes ++default values for all variables; all option groups are enabled by ++default. ++ ++For example, the following 'option-groups.config' would omit locale ++data, but include mathematical functions, and everything else: ++ ++ OPTION_EGLIBC_LOCALES = n ++ OPTION_EGLIBC_LIBM = y ++ ++Like the Linux kernel, EGLIBC supports a similar set of '*config' make ++targets to make it easier to create 'option-groups.config', with all ++dependencies between option groups automatically satisfied. Run ++'make help' to see the list of supported make config targets. For ++example, 'make menuconfig' will update the current config utilising a ++menu based program. ++ ++The option group names and their type (boolean, int, hex, string), help ++description, and dependencies with other option groups, are described by ++'option-groups.def' at the top of the source tree, analogous to the ++'Kconfig' files in the Linux kernel. ++ ++In general, each option group variable controls whether a given set of ++object files in EGLIBC is compiled and included in the final ++libraries, or omitted from the build. ++ ++Each subdirectory's Makefile categorizes its routines, libraries, and ++executables by option group. For example, EGLIBC's 'math/Makefile' ++places the 'libm' library in the OPTION_EGLIBC_LIBM group as follows: ++ ++ extra-libs-$(OPTION_EGLIBC_LIBM) := libm ++ ++Finally, common code in 'Makerules' cites the value of the variable ++'extra-libs-y', selecting only those libraries that belong to enabled ++option groups to be built. ++ ++ ++Current Status and Future Directions ++ ++The EGLIBC component configuration system described here is still ++under development. ++ ++We have used the system to subset some portions of EGLIBC's ++Index: libc/configure.ac +Index: git/configure.ac +=================================================================== +--- git.orig/configure.ac 2014-08-27 07:24:41.196070587 +0000 ++++ git/configure.ac 2014-08-27 07:24:41.656070587 +0000 +@@ -127,6 +127,16 @@ + [sysheaders='']) + AC_SUBST(sysheaders) + ++AC_ARG_WITH([kconfig], ++ AC_HELP_STRING([--with-kconfig=PATH], ++ [location of kconfig tools to use (from Linux ++ kernel builds) to re-use for configuring EGLIBC ++ option groups]), ++ [KCONFIG_TOOLS=$withval], ++ [KCONFIG_TOOLS='']) ++AC_SUBST(KCONFIG_TOOLS) ++ ++ + AC_SUBST(use_default_link) + AC_ARG_WITH([default-link], + AC_HELP_STRING([--with-default-link], +Index: git/config.make.in +=================================================================== +--- git.orig/config.make.in 2014-08-27 07:24:37.560070587 +0000 ++++ git/config.make.in 2014-08-27 07:24:41.656070587 +0000 +@@ -46,6 +46,8 @@ + c++-sysincludes = @CXX_SYSINCLUDES@ + all-warnings = @all_warnings@ + ++kconfig_tools = @KCONFIG_TOOLS@ ++ + have-z-combreloc = @libc_cv_z_combreloc@ + have-z-execstack = @libc_cv_z_execstack@ + have-Bgroup = @libc_cv_Bgroup@ +Index: git/configure +=================================================================== +--- git.orig/configure 2014-08-27 07:24:41.192070587 +0000 ++++ git/configure 2014-08-27 07:24:41.660070587 +0000 +@@ -619,6 +619,7 @@ + PERL + BASH_SHELL + libc_cv_gcc_static_libgcc ++KCONFIG_TOOLS + CXX_SYSINCLUDES + SYSINCLUDES + AUTOCONF +@@ -733,6 +734,7 @@ + with_binutils + with_selinux + with_headers ++with_kconfig + with_default_link + enable_sanity_checks + enable_shared +@@ -1437,6 +1439,9 @@ + --with-selinux if building with SELinux support + --with-headers=PATH location of system headers to use (for example + /usr/src/linux/include) [default=compiler default] ++ --with-kconfig=PATH location of kconfig tools to use (from Linux kernel ++ builds) to re-use for configuring EGLIBC option ++ groups + --with-default-link do not use explicit linker scripts + --with-cpu=CPU select code for CPU variant + +@@ -3400,6 +3405,14 @@ + + + ++# Check whether --with-kconfig was given. ++if test "${with_kconfig+set}" = set;
