[mpich-discuss] About using g95 to compile MPICH2 problem

[謝奇哲]

Dear Jayesh:
  I had trying to re-install MPICH2.
  And using the command
  ./configure F77=g95 FC=g95 FFLAGS=-fno-second-underscore
--prefix=/MPICH2/ 2>&1 | tee c.txt

  When I finished installing, I didn't find the mpif90 in bin file.
  What's problem with me?Can anyon give me some advices?

  Best regards,
  Chi-Che Hsieh
