[osg-users] [GL ES2] Compilation errors on master branch

[Robert Osfield]

HI Jean,

Others have been using GLES2 with OSG svn/trunk without problems so
there must be an issue relating to specific combination of headers.

How did you go about installing your GLES2 version?  What source is it from?

At what point do you get the compile errors you are reporting?

Robert.
