Title: Re: [Oscar-devel] SUSE Linux gcc-fortran or compat-g77
As long as we all agree on which compiler to use, it does not matter to me.
 
I believe compat-g77 will be around (at least in SUSE land) for the next little while, it is available also in 10.1.
 
I took a quick look at the official LAM/MPI and MPICH SUSE RPMs, LAM/MPI was built with gfortran but MPICH was built with g77.
 
I had trouble building our LAM/MPI (7.1.2) with g77.
 
I'll wait for Erich to pitch in regarding this issue, since he built most of the original parallel libraries for SUSE.
 
Also, how do we go about requiring the user have either gcc-fortran or compat-g77 installed?  Should we put that in the "base" prereq?
 
Cheers,
 
Bernard

Personally, as an occasional fortran user, I would suggest the g77 libs.
That is what I use anyway.
