[mpich-discuss] mpich2&open64 shared object compilation bug&fix

[Evren Yurtesen IB]

I was trying to compile mpich2 1.4.1p1 using open64 and oddly it kept 
failing with the following configure options...

--enable-fast=O2 --enable-shared --enable-mpe --with-pmi=slurm 
--with-pm=none

I have googled this and found the following forum post:
http://devgurus.amd.com/thread/146210

Where the exact error message which I was getting was mentioned:
  make[4]: Entering directory 
`/home2/ach/soft/wrfipkd/mpich2-1.3.1/src/binding/f90'
   FC              mpi.f90
make[4]: *** [mpi.lo] Error 1


I have modified the configure script and managed to finish installation. 
(diff below). Can this fix be part of mpich2?
