I used mpicc to compile it. I used ./bjam to compile and ./bjam install boost. Any help is appreciated.

My test program works well. #include <stdio.h>#include "mpi.h" int main(int argc, char* argv[]){ int rank, size; MPI_Init(0,0); MPI_Comm_size(MPI_COMM_WORLD, &size); MPI_Comm_rank(MPI_COMM_WORLD, &rank); printf("I am process %d out of total process \n\n ", rank, size ); MPI_Finalize(); return 0;} What may be the reason for the boost MPI install failure ? How do you compile this? And do you use the same compiler when building Boost?
