[libvirt] [PATCH] compile: fix undefined reference to gnutls_x509_crt_get_dn with gcc-4.6.1

From: soulxu <soulxu(a)soulxu-ThinkPad-T410.(none)&gt; When I compile libvirt with gcc-4.6.1 in ubuntu 11.10, got error as below: CCLD libvirtd /usr/bin/ld: ../src/.libs/libvirt_driver_qemu.a(libvirt_driver_qemu_la-qemu_migration.o): undefined reference to symbol 'gnutls_x509_crt_get_dn@@GNUTLS_1_4' /usr/bin/ld: note: 'gnutls_x509_crt_get_dn@@GNUTLS_1_4' is defined in DSO /usr/lib/x86_64-linux-gnu/libgnutls.so so try adding it to the linker command line /usr/lib/x86_64-linux-gnu/libgnutls.so: could not read symbols: Invalid operation collect2: ld returned 1 exit status make[3]: *** [libvirtd] Error 1 It can compile with gcc-4.5.2 in ubuntu 11.04, but it can not compile with gcc-4.6.1 in ubuntu 11.10. I didn't find reason. Does Anyone know the reason or the different between gcc-4.5.2 and gcc-4.6.1? I still provide a patch for this. Just make it is working now.
