g77 

If for some reason you do not want to use gfortran to compile your 
fortran code, there is still g77.

g77 was an excellent fortran-77 compiler that was part of gcc prior to
gcc version 4.0. g77 had (and still does have) a reputation for being 
able to accept almost any fortran variant ever created.  

g77 binaries are still avaliable.  as is the source, since gcc/g77 is
licensed under the gpl.

Fedora Users

Running Fedora Linux ? g77 is easily available by: 
yum install compat-gcc-34-g77

Build It Yourself


The last release in the gcc3.4 series (3.4.6) was on March 6th, 2006.

Can you still build g77 from source code ?
Let's give it a try:

(USE THE BASH SHELL FOR BEST RESULTS !!!!)




wget http://gcc-uk.internet.bs/releases/gcc-3.4.6/gcc-3.4.6.tar.gz
tar xvzf gcc-3.4.6.tar.gz 
mkdir bin
mkdir run
cd bin
../gcc-3.4.6/configure --enable-languages=c,f77 --disable-checking --prefix=/home/bdavis/g77/run
make CC=/usr/bin/gcc
make install

bdavis@bdavis-desktop:~/g77$ cat a.f
      print*,'hello'
      end
bdavis@bdavis-desktop:~/g77$ /home/bdavis/g77/run/bin/g77 -static a.f
bdavis@bdavis-desktop:~/g77$ ./a.out
 hello


So, it looks like if you really want g77, you can make it yourself 2
years later.

UPDATE 06/01/2010.  Still works.  If you want g77, you can get it.

UPDATE 08/03/2010. A report from a Ubuntu linux user reports that the
above no longer works.

Here is a patchfile:

diff --recursive --context gcc-3.4.6/gcc/collect2.c /home/bdavis/g77_2/gcc-3.4.6/gcc/collect2.c
*** gcc-3.4.6/gcc/collect2.c	2005-01-10 09:25:23.000000000 -0600

Put this in a file in your g77 directory (probably ~/g77 if you followed the above
directions.  I stored it in a file named 'pfile'. Also note I am using my home directory,
which is /home/bdavis.  You will need to change the instructions to reflect where your home
directory is or where you want to build and install g77.

cd
mkdir g77
cd g77
wget http://gcc-uk.internet.bs/releases/gcc-3.4.6/gcc-3.4.6.tar.gz
# get the patchfile in this directory, like a cut and paste into vi
vi pfile
mkdir bin
mkdir run
gunzip gcc-3.4.6.tar
tar xf gcc-3.4.6.tar 
patch -p0  < pfile 
cd bin
../gcc-3.4.6/configure --enable-languages=c,f77  \
--prefix=/home/bdavis/g77/run \
--disable-checking
make
make install



g77 will be in /home/bdavis/g77/run/bin
