[osg-users] [build] Problem with building OSG for Android GLES2.0

[Marc Sticksen]

Hi,

I´m trying to build OSG for Android with GLES2.0.

My cmake line looks like this:

Code:
cmake .. -DOSG_BUILD_PLATFORM_ANDROID=ON -DDYNAMIC_OPENTHREADS=OFF -DDYNAMIC_OPENSCENEGRAPH=OFF -DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF -DOSG_GL_MATRICES_AVAILABLE=ON -DOSG_GL_VERTEX_FUNCS_AVAILABLE=ON -DOSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE=ON -DOSG_GL_FIXED_FUNCTION_AVAILABLE=OFF -DOSG_CPP_EXCEPTIONS_AVAILABLE=OFF -DOSG_GL1_AVAILABLE=OFF -DOSG_GL2_AVAILABLE=OFF -DOSG_GL3_AVAILABLE=OFF -DOSG_GLES1_AVAILABLE=OFF -DOSG_GLES2_AVAILABLE=ON -Dj=2

This seems to be good I guess, fixed function is off and only GLES2 is turned on. Now when I run make, following errors appear:

If I turn off everything but GLES2 and the BUILD_PLATFORM, it compiles...why is there a problem with the matrices and vertex arrays etc?

Thanks for helping...

Hi Marc,

Take a look at this wiki page to see how to configure OSG for OpenGL ES 2 : http://www.openscenegraph.org/projects/osg/wiki/Community/OpenGL-ES

OSG_GL_VERTEX_FUNCS_AVAILABLE and OSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE should be disabled.

Cheers,

Mourad

Quoting the wiki page:

If you don't know how to set GLES1/2 please read OpenGL-ES in OSG wiki.

Aditionally I seriosly suggest that you should read the GLES 2 spec document in Kronos ARB

uhhh...shame on me, I just missed that little link! There´s just too much compressed information on this page. Thanks!

Cheers,
