I tried a compilation with clang-3.3-0.6.rc3.fc19.x86_64 here, using CC=clang ./autogen.sh --disable-introspection and hit some issues related to -fxxx -Wxxx flags clang did not like, but after disabling these (manually for now), compilation worked properly. I had errors with the .gir generation, hence the --disable-introspection, but the errors were not related to undefined __stack_chk_fail_local symbols. Can you give more details about your setup? Also, I assume the build tree was clean (ie there was no stray .o generated with gcc in it?) Christophe

Rereading that log more carefully, it's complaining about a missing symbol in the installed libvirt.so, not in one of the .so that was just built. Are other applications able to link against libvirt? Was libvirt compiled with clang or gcc? Christophe

Hmm, I don't see any warnings at all, compiling with CLang on Linux. Please let us know what you're seeing on BSD ? Daniel
