Dear All,
I tried hard to get a free f90 compiler for linux on the net, also
saw plenty of discussion on this topic in a news group. I got the
following impressions from this exercise. Please correct me if
necessary.
1. VAST90 which used to be free has now become commercial (Indeed,
I used it because it had this nice feature of tolerating already
functional g77 code, and it was free! But it does not allow the
option of array bounds checking which would make debugging a lot
easier for me).
2. There is the "F" compiler from the Fortran company which is free.
However, this is not a true f90/95 compiler as it does not allow
compatibility with f77; e.g., common blocks are not allowed.
It does allow array bounds checking.
3. People talk about the Intel Fortran compiler as being free, but
that seems to be a myth. It is free only for evaluation and not
free for ever, if I understand correctly. After evaluation, I
guess one is expected to buy it.
4. The g95 project seems to be the only hope in this respect, but
it is not clear when it will be ready.
I would appreciate comments/further information.
Regards,
Mahesh Patil
