[Gnash] Gnash not finding GL/gl.h on Ubuntu Dapper.

[Richard Brooklyn]

Hi,

Tried to compile gnash again after a long time of not using it. Get the
following:

 g++ -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I. -I.. -I../server
-I/usr/include -I/usr/include/libxml2 -I/usr/include/SDL
-I/usr/include/SDL -DQT_THREAD_SUPPORT -D_REENTRANT -I.. -I. -I..
-I../server -I/usr/include -I/usr/include/libxml2 -I/usr/include/SDL
-I/usr/include/SDL -g -O2 -Wall -Wp,-MD,.deps/ogl.pp -c ogl.cpp  -fPIC
-DPIC -o .libs/ogl.o
In file included from ogl.h:12,
                 from ogl.cpp:10:
tu_opengl_includes.h:55:20: error: GL/gl.h: No such file or directory

Followed by a lot of 'not declared' errors. Obviously it's not able to
find the gl.h file it needs. On my system, this appears to be this file:

/opt/mesa/include/GL/gl.h

Doing:
sudo ln -s /opt/mesa/include/GL /usr/include/SDL/GL
Fixes the issue. But this is obviously a dirty DIRTY hack...

Just thought you'd want the heads up :-)
