[petsc-users] error compiling on MPI_Win

[hbui]

Hi

When compiling a small petsc example, i got an error as such:

I search over the mailing list and see a post which related to this 
error but i didn't quite understand the answer and the user has also 
discontinued the thread.

I tried to trace back the definition of MPI_Win struct and see as below:

#ifndef PETSC_HAVE_MPI_WIN_CREATE
#define PETSC_HAVE_MPI_WIN_CREATE 1
#endif

#if !defined(PETSC_HAVE_MPI_WIN_CREATE) /* The intent here is to be able 
to compile even without a complete MPI. */
typedef struct MPI_Win_MISSING *MPI_Win;
#endif

For some reason the ./configure define PETSC_HAVE_MPI_WIN_CREATE and 
compiler skip the MPI_Win definition. However, i also don't know where 
the struct MPI_Win_MISSING is defined.

Please advise the method to resolve this compilation error.

My system is Ubuntu 12.04, Gcc 4.6.3.
