OMG. I still have to "cope with" (=fight against) historically grown usage of CVS weekly. The same with EMACS (seriously guys, how can anyone be using it as a mailreader/PIM suite etc too?), procmail (which is ok but cumbersome) and (albeit to a lesser degree) SVN (which tends to corrupt repositories if used multi-site).

I'm ok with makefiles, they are simple and clean. And when you lose the oversight/control of your build processes and the output seems a bit unpredictable, it doesn't matter what solution one uses anyway. But ant is a nice build environment too, hmm...

I am going to experiment with this. Let's see if I can use this to build Blender with OpenGL acceleration! (I know someone did three years ago or so, but the code never appeared.)

Is it possible to get OpenGL support by compiling MesaLib with --enable-gles1 and --enable-gles2 flags? I've compiled MesaLib 7.11.2 with these flags, on device with tanners gcc4-4.

Output from ./configure --enable-gles1 --enable-gles2

Code:

OpenGL:          yes (ES1: yes ES2: yes)

Output from glxgears:

Code:

Nokia-N900-40-4_PR_001:~/build/glx$ ./glxgears 
109 frames in 5.0 seconds = 21.714 FPS
158 frames in 5.0 seconds = 31.515 FPS
155 frames in 5.0 seconds = 30.957 FPS

* Window needs to be fullscreen to actually see the gears
rootsh wmctrl -i -r $(wmctrl -l | grep 'glxgears' | awk '{print $1}') -b add,fullscreen

Code:

Nokia-N900-40-4_PR_001:~/build/glx$ ./glxinfo | grep rende
direct rendering: Yes
OpenGL renderer string: Mesa X11

Full output of glxinfo -v
