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
