One of the most common error messages when trying to start VNL/ATK is

Quote
'Not available', 'libg2c.so.0: cannot open shared object file: No such file or directory'

Quite obviously, this is because the library libg2c is missing. In many cases it is straightforward to install this library from the relevant package/software/update manager (look for libg2c, libf2c or g77), but one needs to pay some attention to which version to install, especially on 64-bit platforms, since VNL is a 32-bit application and therefore needs the corresponding 32-bit g2c library.

Some more detailed advice on specific platform will appear in further posts on this thread!

In general, a good resource for locating missing libraries to download is http://rpm.pbone.net/ (click "Search", then go to "Advanced Search" to be able to select distribution, otherwise you usually get way too many results in the search).

Either you can use the software manager to locate and install the needed package (search for libg2c.so), or you can download the needed packages manually:
Code: [Select]
rpm --install libf2c-3.4.6-11.i386.rpm

In Software Management mark the package "gcc-g77" for install (need Install CD1).

This will install the following 3 packages:
  • glibc-devel-2.3.3-98.32.i686.rpm
  • gcc-3.3.3-43.41.i586.rpm
  • gcc-g77-3.3.3-43.41.i586.rpm
and the problem should be resolved.

Install the GNU Fortran Compiler Runtime Library (containing libg2c.so) to fix the issue.

The library is not located on the installation CDs, so instead use http://rpm.pbone.net to locate a 32-bit version of the library.
Code: [Select]
rpm --install libg2c33-3.3.3-42.5.i586.rpm

Sometimes, after installing the library, you need to link VNL to it:

Go to the VNL lib directory and give the command
Code: [Select]
ln -s /usr/lib/libg2c.so.0.0.0 libg2c.so.0
(or the appropriate location of the lib2c.so.* files).

Missing libg2c.so.0 can be fixed by installing libg2c0 from the Synaptic Package Manager or

Code: [Select]
sudo apt-get install libg2c0

I have downloaded from the link above but computer tells me that the newer version is already installed.
./xtramp: error while loading shared libraries: libf2c.so.2: cannot open shared object file: No such file or directory
Still I get this when I try to run program.
What should I do?

I got an indirect alternative solution to this problem in ubuntu (jaunty)
I downloaded f2c-20000510-5.i386.rpm  (since i could not find the same 32-bit package in .deb) from rpm site then converted .rpm to .deb by alien, i.e
in the terminal type
alien -d f2c-20000510-5.i386.rpm
then execute your problem. It will fix the error.
