Can't find GL/gl.h ¿where should it be?

[Román]

Hi all!

I'm trying to compile a program using OpenGL, but I don have installed the include file GL/gl.h which is needed to compile such aplications.

I don't know wich package (if any) provides this file, and I spent all afternoon triying to find it. ¿Where should it be??? :confused:

Thanks a lot in advance!

/usr/include/GL/gl.h is part of the package mesa-common-dev (mhttp://packages.ubuntu.com/dapper/devel/mesa-common-dev).

Thanks a lot!

Now the obvious following question is ¿Is there any way to find a file in a package without downloading every package?

Use apt-file;

sudo apt-get install apt-file
sudo apt-file update
apt-file search GL/gl.h

:)

Another option is to go to http://packages.ubuntu.com/
and use the "Search the contents of packages" search feature.

Use apt-file;:)

Great, thanks! I think I should investigate a little more on the many apt-* programs :-k

I had a similar problem, but more complicated. I think I may have actually encountered a bug in upgrading to dapper? Here are my notes and a fix;

I've seen this described on a few forums elsewhere as well, but no fix.

Missing GL/gl.h header file in Ubuntu Dapper Drake 6.06

In my Ubuntu Dapper Drake installation, distribution-upgraded
from Hoary 5.10, I was missing GL/gl.h. Note, I was NOT using NVIDIA
drivers on this machine, so that is not a factor for me.

GL/gl.h is provided by the mesa-common-dev package, but strangely that
package was already installed, and dpkg -L mesa-common-dev did not
list GL/gl.h.

apt-file confirmed that GL/gl.h SHOULD be provided by the
mesa-common-dev package.

FIX: apt-get --reinstall install mesa-common-dev

Is Mesa somehow reluctant to add GL/gl.h because it is so often provided by the nvidia drivers?

It is a known bug: https://launchpad.net/distros/ubuntu/+source/mesa/+bug/29435

Thanks hod139 and ifokkema, i didn't know how to search for files within packages, so that really helps me out big time! ubuntu's ease never ceases to amaze me :D

Thanks hod139 and ifokkema
Heh heh, you're welcome. Apt rules!
