I'm trying to build gcc3-g77 package from AUR

Has anybody been able to build package lately?

Answer 1

The program I was trying to build was OMNITAB 80 from http://www.itl.nist.gov/div898/software/omnitab.html
I was getting so many errors about not referring to variables and missing libraries and improper options, I can't even remember, so I thought that was because the compiler I was using was just too obscure and that I needed one that was more like f77.  (kind of like compiling the Linux kernel in MS Visual C instead of gcc... it should be remotely possible but incredibly hard)
So I thought g77 was what I needed, but since you said gfortran and g77 are the same program, that made me try one last time. So I just spent the last 4 hours editing the source code, commenting stuff out, declaring things and making the .f files more gfortran friendly (completely winging it of course, a programming guru could have done it in minutes) and now finally omnitab will compile and run on my machine.
I'll go back and find all the changes I made with patch and diff and then release a PKGBUILD for anyone who wants to run a 1980s console spreadsheet.
Note: There are two optional parts of the program. One is calcomp support which I didn't compile because I don't have a calcomp. If I were to download the xf86-input-calcomp package, despite not having the device, I suppose I would be able to compile this feature but not test it. The other is X11 support. I really wanted to get this working but I need help. All of the source files are Fortran except x11src.c. I was getting errors about there being no "main" function so I just put everything after the include and define lines in one big function called main. It still wouldn't compile and talked about static and non static declarations, so I commented out some declarations and changed the order in which some functions were defined. Eventually compiling it into object code worked, but when the makefile went back and put all the object files together to make the executable it once again gave me tons of errors related to x11src.o. If anyone wants to help that would be great. If not, I'll try using a different C compiler that might not be as picky.
