"libstdc++.so.6: cannot open shared object file: No such file or directory"

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

Or

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.

Solution 1:

You get the error message:

E: Unable to locate package libstdc++.so.6
E: Couldn't find any package by regex 'libstdc++.so.6'

because you tried to install a file libstdc++.so.6 that you can't install, because it is located in a debian package.

You can use apt-file to search for the package that contains that file. To install it, type:

sudo apt-get install apt-file

Then you have to update the index.

sudo apt-file update

After that, you can search for the package which contains the file libstdc++.so.6:

sudo apt-file find libstdc++.so.6

Then you find a lot packages that contains the searched file. In your case, the correct package is libstdc++6:

libstdc++6: /usr/lib/x86_64-linux-gnu/libstdc++.so.6

Then you can install the needed package:

sudo apt-get install libstdc++6

Solution 2:

I think Psychonauts is a 32bit application. You will need to install:

apt-get install lib32stdc++6
