From f1703bcc7a5c507e471e2630b5a2de129100315a Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Mon, 2 Mar 2015 01:32:49 +0000 Subject: [PATCH 05/13] Explicitly link with libm on uclibc Description: We do not need to have the libtool patch anymore for binutils after libtool has been updated upstream it include support for it. However for building gas natively on uclibc systems we have to link it with -lm so that it picks up missing symbols. /local/build_area/BUILD/arm_v5t_le_uclibc/binutils-2.17.50/objdir/libiberty/pic/libiberty.a(floatformat.o): In function `floatformat_from_double': floatformat.c:(.text+0x1ec): undefined reference to `frexp' floatformat.c:(.text+0x2f8): undefined reference to `ldexp' /local/build_area/BUILD/arm_v5t_le_uclibc/binutils-2.17.50/objdir/libiberty/pic/libiberty.a(floatformat.o): In function `floatformat_to_double': floatformat.c:(.text+0x38a): undefined reference to `ldexp' floatformat.c:(.text+0x3d2): undefined reference to `ldexp' floatformat.c:(.text+0x43e): undefined reference to `ldexp' floatformat.c:(.text+0x4e2): undefined reference to `ldexp' collect2: ld returned 1 exit status make[4]: *** [as-new] Error 1 Upstream-Status: Pending Signed-off-by: Khem Raj --- gas/configure.tgt | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/gas/configure.tgt b/gas/configure.tgt index 9abc768..1d92f55 100644 --- a/gas/configure.tgt +++ b/gas/configure.tgt @@ -477,6 +477,12 @@ case ${generic_target} in *-*-netware) fmt=elf em=netware ;; esac +case ${generic_target} in + arm-*-*uclibc*) + need_libm=yes + ;; +esac + case ${cpu_type} in aarch64 | alpha | arm | i386 | ia64 | microblaze | mips | ns32k | or1k | or1knd | pdp11 | ppc | sparc | z80 | z8k) bfd_gas=yes -- 2.1.4
