Missing GL/gl.h

It should be in mesa-common-dev. I saw the same missing header on a system that I upgraded from Breezy to Dapper today, but not one that has been running Dapper for a while. "dpkg -r --force-depends mesa-common-dev" followed by "apt-get install mesa-common-dev" restored it on the system with problems, but I do not know what caused it.

The only clue I found is that "dpkg -L mesa-common-dev" for the problematic package was missing all the /usr/include/GL/*.h files, even though it listed the directory. The package with it showed gl.h, glext.h, gl_mangle.h and osmesa.h in that directory.

I had already copied the gl.h and gl_ext.h files from another pc running Breezy, so I don't know if this workaround worked. But it's still an upgrade bug, methinks.

Another package must have replaced those files and then removed them in a later version.

Had the same problem after an update from Breezy to Dapper, apt-get install --reinstall mesa-common-dev fixed it.

GL/xmesa.h is also missing.

Oh great. This is a bug in breezy that will be a pain try to work around. Basically, we have this in breezy:

libgl1-mesa-dev contains the headers
libgl1-mesa-dev has an unversioned Replaces on mesa-common-dev

And in dapper:

libgl1-mesa-dev depends on mesa-common-dev
mesa-common-dev ships the headers

So, on upgrade, mesa-common-dev is installed first, the forward Replaces lets libgl1-mesa-dev continue to own the files, then the new libgl1-mesa-dev is installed, which no longer contains the files.

I'll go ponder how to solve this sanely.

none of the various dpkg/apt related workarounds works for me right now.

I was wrong. Sorry. Bad use of locate betrayed me! The workarounds FIX it.

I'm running Dapper.

Not sure if this is related. I was missing GL/glu.h and ultimately found the correct package, libglu1-mesa-dev-6.4.1-0ubuntu8. This was on the distribution list, and what apt-get tried to install.

It had a dependency, libglu1-mesa-6.4.1-0ubuntu8, which is totally normal and expected. However, I had already installed libglu1-mesa-6.4.1-0ubuntu7 (note the last character difference). You might think an apt-get install libglu1-mesa would give me the latest, but it did not (yes, I did apt-get update). To fix, I downloaded *ubuntu8 from the web site, and dpkg -i'd it.

My sources file is pretty normal, I think from the regular ubuntu source. If it would help, I could find it for you, but that will have to wait a few hours.

Hi Bill, doing:

  sudo apt-get install libglu-dev

will install the development library for you. To make sure that 'apt' knows about the latest versions of each package available, you will need to do:

  sudo apt-get update

first.

Bill, completely different problem and not visible on my system. Please
do an apt-get update.

It is also a problem on edgy.

from Michael will fix it.
Hmm but what happened.

>> install mesa-common-dev"
this did not install gl.h, don't know why.

A solution can be to extract the nvidia driver and put all the headers
from include into the /usr/include/GL. After programms and programming
against opengl works fine.

Greetings Marc

Adam: maybe we can close this one now?

closing the bug, mesa-common-dev in Feisty has GL/gl.h.
