Note that the recommended way to obtain this information is via pkg-config, using something like $ pkg-config --cflags --libs libvirt If you get an error about libvirt not being found, you probably need to run $ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig or something along those lines beforehand. -- Andrea Bolognani / Red Hat / Virtualization
