libg2c.so.0 and gcc-3.4 issues

Asked by david garcia

My system: uname -a
Linux Ubuntu-1004-lucid-64-minimal 2.6.32-35-server #78-Ubuntu SMP Tue Oct 11 16:26:12 UTC 2011 x86_64 GNU/Linux

Hello, i'm trying to execute a 32 bits binary in my 64bit ubuntu. When i try to run the binary (is a Fortan program, i think), i retrieve

"error while loading shared libraries: libg2c.so.0: cannot open shared object file: No such file or directory"

aptitude install libg2c0

I'm unable to install gcc-3.4 too

Here http://ubuntuforums.org/showthread.php?t=1487901 there is a link to download the libg2c0 deb package created for jaunty, but the link is broken http://packages.ubuntu.com/jaunty/libg2c0

Best regards.

gcc 3.4 is a very old version, that is no longer supported -- you should be using a newer version. Jaunty is also end-of-life, so the packages are not longer online.

According to

http://<email address hidden>/msg18043.html

libg2c was part of the g77 code, which has been deprecated some time ago. Do you have the source code for your fortran program?

No, is a binary and the source code is not available!
Thank you for your help, best regards.

Getting the proper .deb files, the problem is solved

dpkg -i gcc-3.4-base_3.4.6-9_amd64.deb
and finally
dpkg --force- -i libg2c0_3.4.6-6ubuntu5_amd64.deb

Best regards.

Be careful with the above solution -- it is technically not valid, but may appear to work

There is no guarantee that libc shipping with gcc-3.4 and gcc4 are the same -- part of the reason you had to force install.

Your application may provide incorrect results, or crash, as binary compatibility within your package hierarchy is almost certainly not present.
