[projectm-devel] Opengl es 2.0 and Nokia n900

[Daniel S. <ma...@sq...>]

Hi. Im am new to this list.

I am interested in getting projectm running on the n900. It is equipped with opengl es 2.0 gpu with 1.1 compatibility.

I have been reading up on the gl es 2 spec.

I have checked out the projectm 2.0.1 src and tweaked a few things to try and build it but thus far have not suceeded.

First off i disabled ftgl, enabled fbo and gles1 support in cmakelists.txt. I then deleted cmakecache.txt and did a cmake .

I had to alter many files to include GLES/gl.h rather than GL/gl.h
this leads me to the conclusion that although gles 1 support is apparently present it is not maintained.

i have given up for now at soil.o having built the following:

Nokia-N900-42-11:/home/user/projectM-2.0.1-Source# find -name *.o
./Renderer/CMakeFiles/Renderer.dir/Renderable.o
./Renderer/CMakeFiles/Renderer.dir/MilkdropWaveform.o
./Renderer/CMakeFiles/Renderer.dir/RenderItemMatcher.o
./Renderer/CMakeFiles/Renderer.dir/BeatDetect.o
./Renderer/CMakeFiles/Renderer.dir/VideoEcho.o
./Renderer/CMakeFiles/Renderer.dir/ShaderEngine.o
./Renderer/CMakeFiles/Renderer.dir/TextureManager.o
./Renderer/CMakeFiles/Renderer.dir/Waveform.o
./Renderer/CMakeFiles/Renderer.dir/RenderItemDistanceMetric.o
./Renderer/CMakeFiles/Renderer.dir/UserTexture.o
./Renderer/CMakeFiles/Renderer.dir/SOIL/image_helper.o
./Renderer/CMakeFiles/Renderer.dir/SOIL/image_DXT.o
./Renderer/CMakeFiles/Renderer.dir/Filters.o
./Renderer/CMakeFiles/Renderer.dir/FBO.o
./Renderer/CMakeFiles/Renderer.dir/Pipeline.o
./Renderer/CMakeFiles/Renderer.dir/PerlinNoise.o
./Renderer/CMakeFiles/Renderer.dir/Renderer.o
./Renderer/CMakeFiles/Renderer.dir/Shader.o
./Renderer/CMakeFiles/Renderer.dir/PerPixelMesh.o
./Renderer/CMakeFiles/Renderer.dir/PipelineContext.o


Can anybody tell me how long it has been if ever since a gles build has suceeded? Also how much work i can expect to have to put in to get it going?
I have done some work with opengl years ago but am aware that gles is quite different, and that gles 2 at least requires learning the glsl shader language.

I doubt i will find more than the odd one or two hrs a week to look at this and wonder if it is likely to be worth pursuing.

Thanks in advance for any comments.
