[MPICH] mpif90 issues

[Rajeev Thakur]

I don't know what f90main.o is, but it is possible that it might have been
compiled with pgcc or requires some pgcc libraries. Just guessing.

I am thinking this might be a pgi 6.0 error?? I just used mpich2 on both a
32bit machine and 64bit machine and got this again

[wind at fcst3 mpich2-1.0.2p1]$ ./bin/mpif90 
/usr/local/pgi-6.0/linux86/6.0/lib/f90main.o(.text+0x77): In function
`main':
: undefined reference to `MAIN_'


I am just setting these enviroment vars

export F90="pgf90"  
export FC="pgf77"  
export F77="pgf77"

we don't have the license for the C pgi compiler

An analogous way like your old configure command is

<moich2-1.0.2p1_dir>/configure CC=pgcc CXX=pgCC F77=pgf77 F90=pgf90 ...

All the "environmental" variables can be specified as part of configure 
command.

PS. Advantages of putting the env. variables as part of configure
command are 1) the env variables won't corrupt your working environment,
so you can configure MPICH2 with different set of compilers in the same 
shell. 2) the exact configure command and options can be retrieved by a
grep on config.status, e.g.

grep -A 5 configured config.status

or

./config.status --recheck (hits control-c as soon as it runs).
