While building kdelibs using kdesrc-build I am encountering "undefined reference to `UdevQt::..........." Even after installing udev from the default ubuntu repositories I get the same error. How to resolve it?
This is the exact error: -------------------------- [ 43%] Building CXX object solid/solid/CMakeFiles/solid.dir/org_kde_solid_networking_client.o Linking CXX shared library ../../lib/libsolid.so
