So I have been given this code that is useful to my research. I have been reading forums upon forums, websites after websites, trying to get g77 to work and to get a gcc other than gcc-4 to run on my Ubuntu. The reason I have to use g77 compiler is because it is the only thing that works, crazy I know. I tried fort77, f77, gfortran and the code does not compile. My coworker uses g77 and it compiles beautifully. So I just got Ubuntu on my computer and trying to install gcc-3.2, even tried gcc-2.8.1. I follow the directions to the T and I think the problem lies in bootstrap. I type make bootstrap and I get errors back. So I have no clue what to do. Or is there a way I can get around this when I am using gcc to refer to the older version, without having to install an older version? Any information you can provide would be greatly appreciated.

what're errors in bootstrap.

you can disable bootstrap if you want to.

hmmm i check out somethings, and let you know

i think gcc 4.3 can't compile it and we need older gcc to compile it.

only cc and foltran 77 would be enought to compile a foltran 77 compiler.

It used to be : apt-get install g77 .
But in the latest three releases the g77 / gcc-3.4
packages are omitted.

The packages from Ubuntu 'Hardy-updates'
can be installed and work perfectly.
'g77' :
http://packages.ubuntu.com/hardy-updates/g77
i386 : http://de.archive.ubuntu.com/ubuntu/...untu6_i386.deb
> > g77_3.4.6-31ubuntu6_i386.deb

Dependencies :
g77-3.4, gcc-3.4, gcc-3.4-base, libg2c0-dev, libg2c0

Download the six packages, move them to a new empty
folder and install the packages with the command :
sudo dpkg -i *.deb
.....

You can have as many compilers installed at the same
time, as you want, as long as you use the ones build
for Ubuntu.
.....
.....

Do not expect gcc-3.2 to compile on a modern system.
