We use shaders in hildon-desktop. Maybe looking at those helps with the syntax: http://maemo.gitorious.org/fremantle-hildon-desktop/hildon-desktop/blobs/master/src/tidy/tidy-blur-group.c Notice that the GLES shader specification allows the implementation to slack at times when it comes to precisions. http://www.khronos.org/registry/gles/specs/2.0/GLSL_ES_Specification_1.0.17.pdf -Kimmo > > /Jonny > > > On Thu, 25 Feb 2010, Kimmo Hämäläinen wrote: > > > On Wed, 2010-02-24 at 22:37 +0100, ext Jonny Karlsson wrote: > >> I have successfully compiled an OpenGL ES 2.0 program on scratchbox for > >> the FREMANTILE_ARMEL plattform.
