MPI compilation problems with mpicc.bat and mpifc.bat

[Ian_Chivers]

I've found some issues with the batch files

mpicc.bat

and

mpifc.bat

when trying to compile a C++ mpi program.

the batch files contain

echo.

statements which are illegal on windows.

I've had this issue in the past with mpi Fortran code, but not C++ code.

Hi,

Thanks for posting in the Intel forums.

>>> "I've found some issues with the batch files"

Could you please elaborate more on this issue?

Could you please let us know the version of Intel MPI you have been using?

>>>" when trying to compile a C++ mpi program"

Could you please provide us with the sample reproducer and steps to reproduce the issue at our end?

Thanks & Regards

Shivani

I did a grep on the above batch files looking for "^echo"

and found that mpicc.bat and mpifc.bat both contains 

echo.

statements.

Hope this helps

I've installed the latest release and the problem no longer happens.
