Hi Robert, I am using Ubuntu 14.04 64 bit. I was able to reproduce this issue by following those steps: git clone https://github.com/openscenegraph/osg.git cd osg mkdir build cd build cmake -DOSG_GL1_AVAILABLE=OFF -DOSG_GL2_AVAILABLE=OFF -DOSG_GL3_AVAILABLE=OFF -DOSG_GLES1_AVAILABLE=OFF -DOSG_GLES2_AVAILABLE=ON -DOPENGL_INCLUDE_DIR=/usr/include -DOPENGL_LIBRARY=/usr/lib/x86_64-linux-gnu/libGLESv2.so -DOPENGL_egl_LIBRARY=/usr/lib/x86_64-linux-gnu/libEGL.so -DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF -DOSG_GL_MATRICES_AVAILABLE=OFF -DOSG_GL_VERTEX_FUNCS_AVAILABLE=OFF -DOSG_GL_VERTEX_ARRAY_FUNCS_AVAILABLE=OFF -DOSG_GL_FIXED_FUNCTION_AVAILABLE=OFF -DOSG_CPP_EXCEPTIONS_AVAILABLE=OFF .. make > At what point do you get the compile errors you are reporting?
