Re: [OMPI users] Windows CMake build problems ...

[Shiqing Fan]

Hi Charlie,
There is definitely something wrong in the cxx library for Windows, but 
it's still not very clear to me yet. We'll try to find the reason and 
fix it.

Thanks for reporting it.


Regards,
Shiqing

However, none of the extended or simple c++ examples work, they all 
die with the same link error.

For instance: mpi_gather.cc
______________________________________________

#include <stdio.h>
#include <mpi.h>
#include <math.h>

using namespace MPI;

int main(int argc, char* argv[]) {
  int rank;
  int recvcount,sendcount;
  int reap[8];
  int sow[2];

  Init(argc,argv);
  rank=COMM_WORLD.Get_rank();
  sendcount=2;
  sow[0]=rank; sow[1]=-rank;
  if(rank==1) {
    recvcount=2;
  }
  COMM_WORLD.Gather(sow,sendcount,INT,reap,recvcount,INT,1);
  if(rank==1) {
    printf("P:%d",rank);
    for(int i=0;i<8;++i) {
      printf(" %2d ",reap[i]);
    }
    printf("\n");
  }
  Finalize();
}

Every c++ dies with this link error.

    Yeah, that was it. Thanks.

        Hi Charlie ,

        Did you run the mpicc command in the Visual Studio Command
        Prompt? Is it
        possible for you to call cl.exe from there? Because it sounds
        like the
        VS compiler was not found.


        Regards,
        Shiqing
