Likewise.

Your approach to a fix is correct, but I need to know whether to use
the patch as-is or whether we just need one library rather than two.


Yes, I get a second link error. When I just add GNUTLS_LIBS to there, I get another error, as below:

/usr/bin/ld: ../src/.libs/libvirt_driver_qemu.a(libvirt_driver_qemu_la-qemu_domain.o): undefined reference to symbol 'xmlXPathRegisterNs@@LIBXML2_2.4.30' /usr/bin/ld: note: 'xmlXPathRegisterNs@@LIBXML2_2.4.30' is defined in DSO /usr/lib/libxml2.so so try adding it to the linker command line

In which case, ACK and pushed.

Your original patch was (mistakenly) attributed to <soulxu soulxu-ThinkPad-T410 (none)>, which is not a valid address; you should probably fix your ~/.gitconfig settings on that computer. Hopefully I was correct in re-attributing authorship to the email you used for previous patches.

Thanks!
