Missing OpenGL headers

[Matthew Dempsky]

I cannot find /usr/include/GL/gl.h in Dapper:

    shelly@muffin:~$ apt-file -l search /usr/include/GL/gl.h
    libgl1-mesa-dev
    mesa-common-dev
    shelly@muffin:~$ dpkg -L libgl1-mesa-dev mesa-common-dev | grep gl.h
    shelly@muffin:~$

This also applies to glext.h and possibly others.

Hi Matthew, thanks for you bug report.

The various header files are you after are in the following development packages:

$ dpkg -S /usr/include/GL/gl* | sort
libgl1-mesa-dev: /usr/include/GL/glxext.h
libgl1-mesa-dev: /usr/include/GL/glx.h
libgl1-mesa-dev: /usr/include/GL/glx_mangle.h
libglu1-mesa-dev: /usr/include/GL/glu.h
libglu1-mesa-dev: /usr/include/GL/glu_mangle.h
mesa-common-dev: /usr/include/GL/glext.h
mesa-common-dev: /usr/include/GL/gl.h
mesa-common-dev: /usr/include/GL/gl_mangle.h
x11proto-gl-dev: /usr/include/GL/glxint.h
x11proto-gl-dev: /usr/include/GL/glxmd.h
x11proto-gl-dev: /usr/include/GL/glxproto.h
x11proto-gl-dev: /usr/include/GL/glxtokens.h

These in turn have nice high-level Provides so that all you need to do is:

  sudo apt-get install libgl-dev libglu-dev

Hm, packages.ubuntu.com confirms that there's a gl.h file in mesa-common-dev, so closing this bug is fine.

(I know the headers went missing after upgrading because OpenGL programming assignments that compiled fine before could no longer find them, but I've since then had to give up on testing Dapper.)
