Subject: [PATCH] [m4/libtool.m4] linker error for powerpc64le-unknown-linux-gnu
|
|
|
|
Hi all,
|
|
|
|
1) As we might know, Gentoo has powerpc64le-unknown-linux-gnu compiler
|
|
|
|
leno@localhost ~ $ powerpc64le-unknown-linux-gnu-gcc -v
|
|
|
|
Using built-in specs.
|
|
|
|
COLLECT_GCC=/usr/powerpc64le-unknown-linux-gnu/gcc-bin/5.3.0/powerpc64le-unknown-linux-gnu-gcc
|
|
|
|
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/powerpc64le-unknown-linux-gnu/5.3.0/lto-wrapper
|
|
|
|
Target: powerpc64le-unknown-linux-gnu
|
|
|
|
Configured with:
|
|
/var/tmp/portage/sys-devel/gcc-5.3.0/work/gcc-5.3.0/configure
|
|
--host=powerpc64le-unknown-linux-gnu --build=powerpc64le-unknown-linux-gnu
|
|
--prefix=/usr --bindir=/usr/powerpc64le-unknown-linux-gnu/gcc-bin/5.3.0

--enable-libgomp --disable-libmudflap --disable-libssp --disable-libcilkrts
|
|
--enable-lto --without-isl --enable-libsanitizer
|
|
|
|
Thread model: posix
|
|
|
|
gcc version 5.3.0 (Gentoo 5.3.0 p1.0, pie-0.6.5)
|
|
|
|
2) And the supported emulations
|
|
|
|
leno@localhost ~ $ powerpc64le-unknown-linux-gnu-ld -V
|
|
GNU ld (Gentoo 2.25.1 p1.1) 2.25.1
|
|
Supported emulations:
|
|
elf64lppc
|
|
elf32lppc
|
|
elf32lppclinux
|
|
elf32lppcsim
|
|
|
|
3) But when I set CHOST="powerpc64le-unkown-linux-gnu" in Gentoo and
|
|
execute aclocal, automake, libtoolize --copy --force, autoconf. When I
|
|
glance in the latest m4/libtool.m4 :
|
|
|
|
if AC_TRY_EVAL(ac_compile); then
|
|
case `/usr/bin/file conftest.o` in
|
|
*32-bit*)
|
|
case $host in
|
|
...
|
|
powerpc64le-*linux*)
|
|
LD="${LD-ld} -m elf32lppclinux"
|
|
;;
|
|
powerpc64-*linux*)
|
|
LD="${LD-ld} -m elf32ppclinux"
|
|
;;
|
|
...
|
|
*64-bit*)
|
|
case $host in
|
|
...
|
|
powerpcle-*linux*)
|
|
LD="${LD-ld} -m elf64lppc"
|
|
;;
|
|
powerpc-*linux*)
|
|
LD="${LD-ld} -m elf64ppc"
|
|
;;
|
|
...
|
|
|
|
seems linked to $LD='$LD-ld -m elf64ppc' and failed to compile packages.
|
|
|
|
4) Below is my workaround patch and works fine for this case. If this is
|
|
OK for you, Could this to be merged in upstream? Thanks
