You error is that the flag that enables OpenMP handling in GCC is -fopenmp and not -openmp. With -fopenmp the path to omp.h is added automatically to the list of include paths.

As to where the actual omp.h file is located - it is usually located together with the other support files in the library folder. On RedHat-based distros it is in /usr/lib/gcc/<arch>-redhat-linux/<version>/include/omp.h where <arch> is the architecture (e.g. x86_64) and <version> is the GCC version (e.g. 4.4.4). Other distros may choose a different place.

One more thing - the option to specify the output executable is -o (small letter O). -O (capital letter O) enables some basic optimisations on the compiled code.
