[mvapich-discuss] Re: mpif90 wrapper compile error when mpif.h is needed

[Brian Curtis]

Giri,


Depending on the platform/compiler, you can link with libg2c (Linux  
F77), U77 (HPUX), or PEPCF90 (Intel ifc).  MVAPICH2 contains some  
intelligence during configuration that resolves this issue for many  
(if not all) supported platforms that we will look at backporting.   
Can you provide a simple test program so that we can replicate this  
issue with MVAPICH?
