I think that were _guard and something about stack_smashing. I worked around the problem by editing the apropriate file of libloader by putting in an #undef __SSP__ just before thos symbols are defined. With this xorg-x11 compiled through and works. (go into xc/programs/xfree/ whatever, search for libloader and grep for _guard, I don't have everything memorized...) So, what goes wrong in xorg-x11 configuration that it enables __SSP__ which glibc doesn't support? Reproducible: Always Steps to Reproduce: 1. 2. 3.

Commenting out echo "#define ProPoliceSupport YES" >> ${HOSTCONF} made it compile through. So we need some sort of detection for SSP.
Every glibc in the tree should support it, so I'm not really sure what's happening here.
Well, then this glibc build (installed a few days ago) obviously does something wrong. The fun began with tar, as this one was complaining about undefined reference to _guard in libc6.so. So I needed to get a binary (and got a win32 compile), compiled tar by hand, copied to /bin and reemerged tar...
what does this show on your system: $ readelf -s /lib/libc.so.6 | grep __guard
nothing
your glibc is broken then, re-emerge it
Ok, I now know what went wrong. My fault, but I had reason to do: I commented out glibc-2.3.5-propolice-guard-functions.patch, because glibs didn't want to compile using the gcc 3.4.4 as it doesn't know -fno-stack-protector. I don't know whther gcc has been updated to support it now? (I used official ebuil when I emerged gcc 3.4.4 when it was ~x86, iirc) Well, I'll reemerge gcc and try to compile glibc again. Sorry for the noise. (Nevertheless I still think a bit more auto detection wouldn't hurt.)
Ok, closing because of the above comment
