Bug 266172 – sys-libs/glibc-2.4-r4 headers fail with sys-devel/crossdev --target i586-pc-linux-gnu on amd64

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Nathan Phillip Brink (binki) (RETIRED) 2009-04-14 21:06:32 UTC]

I run:
crossdev --target i586-pc-linux-gnu
and then the crossdev process fails on glibc-headers.

It seems that glibc is incorrectly using my x86_64-pc-linux-gnu-gcc to test if the assembler supports TLS stuff. It uses ${CC-cc} to decide which computer to run in glibc-2.4/sysdeps/i386/elf/configure.in. It should, IMHO, directly call the i585-pc-linux-gnu-as from the already-installed cross binutils packages.

I'll attach the logs crossdev asked for, but I think the following output is most interesting:

An error in glibc's config.log:
configure:7: checking for i386 TLS support
configure:29: x86_64-pc-linux-gnu-gcc -c  -pipe -march=athlon64 -ggdb -O2 -fno-strict-aliasing conftest.s 1>&5
conftest.s: Assembler messages:

conftest.s:14: Error: @NTPOFF reloc is not supported with 64-bit output format
conftest.s:14: Error: junk `@NTPOFF' after expression

I tried compiling the excerpt found in glibc-2.4/sysdeps/i386/elf/configure.in with my system's x86_64-pc-linux-gnu-gcc and got the same error, but I got no error when specifying -m32.

I have no idea what should happen (i.e., what a patch would contain) :-(.

The following lines from this attachment look interesting:
``running configure fragment for sysdeps/i386/elf
checking for i386 TLS support... no
running configure fragment for nptl/sysdeps/pthread''

use glibc-2.9.  we just dont have the resources to support anything other than latest stable+ (which is glibc-2.8+).

Sorry, I didn't realize that crossdev was using a very old version of glibc
