# Library Issues when trying to run blender game on different computers

I've made some games on my home computer (running Ubuntu) using blender (saving it using bpy.ops.wm.save_as_runtime()). When I try to run that file on my work computer (running CentOS) i get a load of library errors EG:

error while loading shared libraries: libpng16.so.16: cannot open shared object file: No such file or directory


I've just ran blender from the work computer and saved a game which then runs fine and there's no errors. Is the problem the different OS?

Because I have so many games which are created running various scripts, it's much much easier if I can just use the games created on the home computer (I don't have super user privileges at work).

Are my only two options to either install all the required libraries or create the games on the work computer? Or is there a nicer way of exporting games that will save me?

• I started doing this but there's quite a few and also I got stuck when one of the libraries required sudo for the make install command – A. Bollans Oct 24 '18 at 12:20
• You could also put all the needed libraries into e.g. a lib folder and then start with LD_LIBRARY_PATH=lib/ ./mygame. You can download e.g. libpng16 from packages.debian.org, select the desired architecture, download the deb packages, extract (don't install) it with an archive manager, and copy the libpng16.so.16 where you need it. Repeat that for the other dependencies. – Ignatiamus Oct 24 '18 at 12:21
