The syntax looks OK now. The error message implies the the omp_get_num_procs program cannot be found in any of the standard locations, so you may need to provide the full path. As I said before, you will not get the correct answer from the call to system; see the man page for details. In order to get the correct number you need to connect the external command's stdout stream to your application, which you can then read and process as required.

[edit]
You need to re-read k5054's message above.
