Bug 443632 – cross-arm-hardfloat-linux-gnueabi/glibc-2.16.0: headers no longer works

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Andrej Gelenberg 2012-11-17 13:52:48 UTC]

I think due to not jet compiled gcc, configure script fail with:

 checking whether gcc implicitly enables -fstack-protector... arm-hardfloat-linux-gnueabi-nm: conftest.o: File format is ambiguous
 arm-hardfloat-linux-gnueabi-nm: Matching formats: elf64-little elf64-x86-64-nacl elf64-x86-64-sol2 elf64-x86-64

erleare in the configure output:
 checking for arm-hardfloat-linux-gnueabi-gcc... gcc


Reproducible: Always

Got compiled as following:
crossdev -t arm-hardfloat-linux-gnueabi -s1 --without-headers

and with this patch:
diff --git a/sys-libs/glibc/files/eblits/src_compile.eblit b/sys-libs/glibc/files/eblits/src_compile.eblit
index cb4cc0b..1bb3c96 100644

It seems, that this workaround don't work anymore.

eblit and ebuild patch

This pacth do the trick for me.
1. "CC=gcc"-trick don't needed anymore, if you build only header
2. don't ignore binutils and gcc dependencies on crosscompile_opts_headers-only
3. systemtap useflag don't work for arm jet

should be all set now in the tree; thanks for the report!

Please remove systemtap use flag for arm platform, it won't build with systemtap use flag.
