What errors are you getting from them ? I incrementally added them one by one, as I got DSO errors about libxml2 and dbus as below, in sequence: CCLD qemuxml2argvtest /usr/bin/ld: ../src/.libs/libvirt_driver_qemu_impl.a(libvirt_driver_qemu_impl_la-qemu_domain.o): undefined reference to symbol 'xmlXPathRegisterNs@(a)LIBXML2_2.4.30' /usr/bin/ld: note: 'xmlXPathRegisterNs@(a)LIBXML2_2.4.30' is defined in DSO /usr/lib/x86_64-linux-gnu/libxml2.so.2 so try adding it to the linker command line /usr/lib/x86_64-linux-gnu/libxml2.so.2: could not read symbols: Invalid operation collect2: error: ld returned 1 exit status [ and ] /usr/bin/ld: ../src/.libs/libvirt_driver_network_impl.a(libvirt_driver_network_impl_la-bridge_driver.o): undefined reference to symbol 'dbus_bus_add_match' /usr/bin/ld: note: 'dbus_bus_add_match' is defined in DSO /lib/x86_64-linux-gnu/libdbus-1.so.3 so try adding it to the linker command line /lib/x86_64-linux-gnu/libdbus-1.so.3: could not read symbols: Invalid operation collect2: error: ld returned 1 exit status
