<br><font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">I was wondering if in <b>$PETSC_DIR/include/finclude/petscdef.h</b> :</font>
<br>
<br><font size=2 face="sans-serif"><b> 50 #if defined(PETSC_HAVE_MPIUNI)</b></font>
<br><font size=2 face="sans-serif"><b> 51 #define MPI_Comm PetscFortranInt</b></font>
<br><font size=2 face="sans-serif"><b> 52 #define PetscMPIInt PetscFortranInt</b></font>
<br><font size=2 face="sans-serif"><b> 53 #else</b></font>
<br><font size=2 face="sans-serif"><b> 54 #define MPI_Comm integer</b></font>
<br><font size=2 face="sans-serif"><b> 55 #define PetscMPIInt integer</b></font>
<br><font size=2 face="sans-serif"><b> 56 #endif</b></font>
<br>
<br><font size=2 face="sans-serif">the integer declaration should not be changed to something dependent on PETSC_SIZEOF_INT. </font>
<br>
<br><font size=2 face="sans-serif">Regards,</font>
