Hi<BR>><BR>> I have no problem to compile & run the sample fpi.f using
fmpich2s.lib. Actually, I have identified the culprit: MPI_SEND/RECV work find
with integer, but have problem with string.<BR>><BR>> The main reason I
beleive is that, in Fortran, different compiler treats the string arguments
differently: either add the string length as a invisible argument immediately
after the string pointer, or the string lengh is added as a invisible arguments
at the end of arguments list. So in my understanding MPI_SEND/RECV will have 28
byte of arguments for integer, but 32 byte of arguments for string because the
invisible string length argument.<BR>><BR>> It will cause crash if the
positions of the invisible string length arguments are different in the .obj
file and in fmpich2s.lib. The following program dimenstrate this<BR>><BR>>
