`__stack_chk_fail' error in 926 and later revisions (i386)

[Eleni Maria Stea]

When I build mir trunk (revisions 926 and later revisions) I get the following error:

/usr/lib/i386-linux-gnu/libc_nonshared.a(stack_chk_fail_local.oS): In function `__stack_chk_fail_local':
(.text+0x10): undefined reference to `__stack_chk_fail'
collect2: error: ld returned 1 exit status
make[2]: *** [lib/libmirplatform.so] Error 1
make[1]: *** [src/platform/graphics/CMakeFiles/mirplatform.dir/all] Error 2

$ uname -a
Linux qubby 3.10.0-5-generic #15-Ubuntu SMP Wed Jul 24 19:44:23 UTC 2013 i686 i686 i686 GNU/Linux

The error seems to occur only in i386 systems

[Alexandros Frantzis (afrantzis)]

Confirmed in a i686 chroot.

Explicitly linking libmirplatform.so against libc (-lc) solves the problem, but it's not clear why this is needed (i.e. why libc is not used by default).

[Daniel van Vugt (vanvugt)]

Looks like we've mixed up shared and non-shared copies of libc. We should ensure all libraries (including static ones) are linking to the dynamic libc.

FWIW another workaround is:

And a further workaround is to use clang++ instead of g++
