[MPICH] linking problem with mpif77/mpicc/..

[Mark Roberts]

Hi, I have installed mpich2-1.0.2p1 and had no error messages during the
installation process.  mpd etc all work fine.  However, when I try and
compile a programme I get error messages like the following

[roberts at nelson ~]$ mpicc
/usr/lib/gcc/x86_64-redhat-linux/3.4.3/../../../../lib64/crt1.o(.text
+0x21): In function `_start':
: undefined reference to `main'
collect2: ld returned 1 exit status
[roberts at nelson ~]$ mpif77
/usr/lib/gcc/x86_64-redhat-linux/3.4.3/libfrtbegin.a(frtbegin.o)(.text
+0x1e): In function `main':
: undefined reference to `MAIN__'
collect2: ld returned 1 exit status
[roberts at nelson ~]$

Clearly something is not linked properly, but I am not sure what.  I had
the same problem trying to install the same version on another machine.
Has anyone experianced the same problem / can suggest how to fix it?

Thanks,
