From 589cc10e54b95607d2728ee37e9387140bf5eb32 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Mon, 2 Mar 2015 01:32:49 +0000 Subject: [PATCH 05/12] 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 0b490d4..086e0d2 100644 --- a/gas/configure.tgt +++ b/gas/configure.tgt @@ -487,6 +487,12 @@ 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 -- 2.7.0
