Thanks! Installed libvirt-devel and I don't get 'No package 'libvirt' found '. But now it fails with 'No package 'libcmpiutil' found'. I worked aorund the problem by setting the following environment variables LIBCU_CFLAGS=-I/usr/include/ LIBCU_LIBS="-L/usr/lib -lcmpiutil -lz -lm" and successfully built libvirt-cim. Thats probably not the correct way of solving this problem, I guess, is it? (Sorry for my ignorance I am more of Ant/Maven build person, and hasn't done lot of make builds :- ( ) I have downloaded libcmpiutil source tar from ftp://libvirt.org/libvirt/CIM/libcmpiutil-0.4.tar.gz and built it and installed. What is the correct way of solving the above mentioned problem? Is there a libcmpiutil-devel package that I should install? Thanks Gopal.
