Re: Compiling after f2c

Thanks Tim. It is true that I'm on my own, and I'm
also  kind of lost. All this is new for me.

I just followed the instructions in the f2c manual to
convert Fortran 77 code into C and then compile it. It
seems this is not enough or even right. For example,
there is no main_ line in any of .c files after
translation. I just don't know what are the f2c
main.o or the f2c link script.

I found the f2c RPM for Fedora 7 in x86-64 machines at
http://rpm.pbone.net/index.php3/stat/4/idpl/4706905/com/f2c-20031026-3.fc7_90.x86_64.rpm.html

I need the code in C to make some .mex files in
Octave. At this point I'm compiling to check if
executables are properly generated.

I look forward.
Thanks again
