[OE-core] meta-toolchain doesn't compile working binaries

[Björn Krombholz]

Hi,

I'm having trouble building a working toolchain (meta-toolchain) on yocto-1.4 release.

Buildsystem is x86_64, on current Debian Sid.

The problem seems to be with ld-linux[...].so, SDKMACHINE doesn't seem to matter (x86_64 and i686 produce broken binaries).

The effect is, that (almost) every binary in the toolchain segfaults when being run.


Example m4:
(in /usr/local/oecore-x86_64/sysroots/x86_64-angstromsdk-linux)

Host ld:
$ usr/bin/m4 --help
Segmentation fault

Explicitly using the toolchain ld:
$ lib/ld-linux-x86-64.so.2 usr/bin/m4 --help
Usage: usr/bin/m4 [OPTION]... [FILE]...
[...]


Comparing the build with a toolchain created on Jul 30th 2013 (which works fine) I see one major difference:

Old (working) toolchain:
$ ldd m4
        linux-vdso.so.1 (0x00007fffdae00000)
        libc.so.6 => /usr/local/oecore-x86_64.old_201307/sysroots/x86_64-angstromsdk-linux/usr/bin/./../../lib/libc.so.6 (0x00007f6a71ed0000)
        /usr/local/oecore-x86_64/sysroots/x86_64-angstromsdk-linux/lib/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2 (0x00007f6a72280000)


New (broken) toolchain:
$ ldd m4
        linux-vdso.so.1 (0x00007fff36e00000)
        libc.so.6 => /usr/local/oecore-x86_64/sysroots/x86_64-angstromsdk-linux/usr/bin/./../../lib/libc.so.6 (0x00007f00e7860000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f00e7c10000)


The internal toolchain (from tmp/build/) is working fine, though the ldd output looks similar to the broken built one:

[...]build/tmp-angstrom_v2013_06-eglibc/sysroots/x86_64-linux/usr/bin$ ldd m4 
        linux-vdso.so.1 (0x00007fff9fdc8000)                                                                                                                                                                                                                                   
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f481cda8000)                                                                                                                                                                                                      
        /lib64/ld-linux-x86-64.so.2 (0x00007f481d188000)

ATM, on Debian Sid /lib64/ld-linux-x86-64.so.2 is just a link /lib64/ld-linux-x86-64.so.2 -> /lib/x86_64-linux-gnu/ld-2.18.so

I'd appreciate if someone could give me a hint on this matter, or a point me in a direction, where the problem might be.
As mentioned I already tried changing the SDKMACHINE and a completely clean build folder with no effect.


Thanks
Björn
