#include <mpi.h>
#include <stdio.h>
int main(int argc, char *argv[])
{
printf("%d %d %d\n", OMPI_MAJOR_VERSION,
OMPI_MINOR_VERSION,OMPI_RELEASE_VERSION);
return 0;
}
returns:
test.cpp: In function ‘int main(int, char**)’:
test.cpp:11: error: ‘OMPI_MAJOR_VERSION’ was not declared in this scope
test.cpp:11: error: ‘OMPI_MINOR_VERSION’ was not declared in this scope
test.cpp:11: error: ‘OMPI_RELEASE_VERSION’ was not declared in this scope
So, I am definitely using another library (mpich).
Thanks one more time!!! I will try to fix it and come back with results.
