How to make Ubuntu not notice one lib?

Question

ubuntu

Hello. I have Ubuntu 14.04 x64. There is one application of the 9*th year, written for x32 and used to calculate neutron characteristics, but that's not the point. It didn't run because there wasn't a certain Fortran lib. When I installed the lib, the application swore that it was 64, but I needed 32. I manually installed the lib for x32, the application counts everything correctly, but now I have a brick in the corner, and when I install something through the apt-get install, the terminal issues:
sudo apt-get install artha
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
artha : Depends: wordnet but it is not going to be installed
Recommendations: wordnet-sense-index but it is not going to be installed
libg2c0:i386 : Depends: gcc-3.4-base:i386 (= 3.4.6-6ubuntu5) but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
How can I make Linux not notice the lib I need, but at the same time the application works properly?

Answer 1

I think it's worth digging towards using LD_LIBRARY_PATH .
For example, copy the old lib somewhere in /usr/local/my_lib, update the system so that it does not swear, and call my_program through a similar script:

#!/bin/sh
export LD_LIBRARY_PATH=/usr/local/my_lib:$LD_LIBRARY_PATH
exec /usr/bin/my_program $*

PS If you also indicate Linux in the tags, you can affect a larger audience.

If you need this lib for a specific application, then, as an option, remove the lib from the system, build it separately and run the specific application beforehand by doing export LD_LIBRARY_PATH.
