I wrastled with the program according to the info in this question. Now it is installed but I can't figure out how to run it. A friend running the same version of Ubuntu had no problems getting it to start after installing it the same way.
This is what I've done:
$ ./Psychonauts ./Psychonauts: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
So I went ahead and:
$ sudo apt-get install libstdc++.so.6 Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libstdc++.so.6 E: Couldn't find any package by regex 'libstdc++.so.6'
It should be noted that I only started using Linux a few days ago.
Okay, so I did manage to install apt-file and apt-file update.
However then we hit another snag.
usagiyojimbo@Usagi:~$ sudo apt-file find libstdc++.so.6 [sudo] password for usagiyojimbo: E: The cache is empty. You need to run 'apt-file update' first.
I have done that, when I do it says:
File is up-to-date. Ignoring source without Contents File: a link they won't let me post
File is up-to-date. Downloading Index a link No Index available. Downloading complete file a link
I am still getting the same error when I try to run Psychonauts.
