I need to download a Fortran 77 compiler to run a .f file for a school project on OPENSUSE.

I have the latest version of opensuse (12.2).

I have installed every last fortran related rpm from the repository: gcc-fortran, gcc33-fortran, gcc47-fortran, and still can't compile and execute the simple .f file.

From my research on the net i understand the gcc no longer hosts f77 compiler on any versions greater the 4.0.As well they no longer have the gcc-g77 compiler either. Why they would do this, i do not know because it seems to me that a number of people has had the same issue.

I have also tried to download the compat-g77 rpm, but have ran into dependency issues.

I am a newbi at opensuse, i know a few command lines to get me around the terminal but that is it. I have tried to download earlier versions of gcc but i don't know how to handle the file. There are alot of .h, .c and other files that i don't know what to do with.

Could someone could please guide me from scratch ( spoon feed me if you will) on how to set up a fortran 77 compiler on Opensuse 12.2 to run these .f files

Thank you

Welcome to LQ.

# zypper in gcc33-fortran

The package provides /usr/bin/g77-3.3

I have already Zyppered gcc33-fortran and installed it, and i still cannot compile the .f files. Maybe i'm doing something wrong or i'm not using the gcc33-fortran correctly, i don't know. All i know is that when i use the g77 or f77 command the terminal does not recognize either.

Can you explain to me how i can go about using gcc33-fortran to compile the .f files.

Ok, i see that i have g77-3.3 in the root/usr/bin. Now, how do i get this to work, or how do i use this to compile my .f file? what is the command line used operate this g77 to compile the .f files?

Because when i use "g77 -c filename.f" the terminal is telling me g77 is a typo.

Ok, i have it! I figured it out and now i look like a fool. No matter though. For any one else that is experiencing the same problem here is the solution.

Zypper/install the gcc33-fortran package, it does host g77-3.3 package for Fortran 77. Now, instead of using the conventional "g77" command to compile and run the program as i did, use "g77-3.3" in your command as it is saved under that title.

Thank you

Or : $ cd /usr/bin/

# ln -s g77-3.3 g77
# ln -s g77-3.3 f77

... Then you will have the *77 for programs looking for g77 or f77.

If you did need an alternate, I believe OpenWatcom have a FORTRAN 77 compiler available still.
