I get the following error message when I compile openmpi V1.5.1:

  CXX    otfprofile-otfprofile.o
../../../../../../../../../openmpi-1.5.1-src/ompi/contrib/vt/vt/extlib/otf/tools/otfprofile/otfprofile.cpp:11:18: erreur: omp.h : Aucun fichier ou dossier de ce type

../../../../../../../../../openmpi-1.5.1-src/ompi/contrib/vt/vt/extlib/otf/tools/otfprofile/otfprofile.cpp:471: erreur: ‘omp_get_num_threads’ was not declared in this scope

The compiler doesn't find the omp.h file.
What happens ?

Best
