Hi, the header file 'omp.h' belongs to the compiler, so if OpenMP is enabled by a specific compiler option (e.g. '-fopenmp' for GNU) the compiler should actually know where the header file is located. There is no need to install any additional OpenMP packages.
The header include at the indicated source line is surrounded by the following preprocessor condition: #ifdef _OPENMP # include <omp.h> #endif It seems to me that the preprocessor macro is defined although OpenMP is disabled or the compiler doesn't support OpenMP. Which compiler are you using? If the compiler supports OpenMP - where is the 'omp.h' located? If you have a suitable 'omp.h', could you please try to specify its path in the preprocessor flags: $ ./configure CPPFLAGS=-I<path-to-omp.h> ... To have a working OpenMPI 1.5.1 for now please perform the following steps: $ cd openmpi-1.5.1/ompi/contrib/vt/vt/extlib/otf/tools/otfprofile $ cat otfprofile.cpp | sed -e "s/_OPENMP/NEVER_DEFINED/" >tmp $ mv tmp otfprofile.cpp Matthias Jurenz > On Dec 16, 2010, at 6:49 AM, Jeff Squyres wrote: > > Hmm.
