OSError: libGL.so: cannot open shared object file: No such file or directory

how to solve it?

[Anders Blom]

Which Linux? Please check

Code

ls -l /usr/lib/*GL*

If you are missing libGL.so there, you need to link it up manually. This is known to be the case on e.g. Ubuntu. If you post the output of the command above, we can provide the exact command you need to give to fix it.

Ubuntu

[Anders Blom]

Right, Ubuntu is for some reason missing a link "libGL.so" in their /usr/bin, so you have to create it yourself. Assuming your actual OpenGL is "libGL.so.1.2" (it might not be, hence the need for the check mentioned in my previous post), you need to do this:

Code

sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so

But first check that you have "libGL.so.1.2" in /usr/lib; you might have "libGL.so.1" or something else instead, depending on the video drivers.

So, the command in the previous is appropriate. Just execute it, and then try to start VNL again!

Dear all,
I tried the code: ls -l /usr/lib/*GL* for checking the LibGL then in the terminal window they notice that:

hien911@Famhieido:~$ ls -l /usr/lib/*GL*
lrwxrwxrwx 1 root root     16 2012-06-20 21:16 /usr/lib/libGLEW.so.1.5 -> libGLEW.so.1.5.0
-rw-r--r-- 1 root root 225068 2008-02-12 01:48 /usr/lib/libGLEW.so.1.5.0
lrwxrwxrwx 1 root root     12 2012-06-20 21:16 /usr/lib/libGL.so.1 -> libGL.so.1.2
-rw-r--r-- 1 root root 394924 2008-04-06 07:06 /usr/lib/libGL.so.1.2

-rw-r--r-- 1 root root 532568 2008-04-06 07:06 /usr/lib/libGLU.so.1.3.070002

so... how to execute it, and then  how try to start VNL again!
I don't know .... please help me!

[Anders Blom]

Right, and then as written above you do

Code

sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so

and you should be able to start VNL.
