From checking out the latest from trunk if I turn on via cmake building Nvidia :

BUILD_NVIDIA_OPENCL_DEMOS:BOOL=ON


I get the following result:

On a side note, I see I need to buy a newer system for the upcoming Bullet 3.x release. Thanks for that heads up.

I get the same error when building the nvidia opencl demos. I'm using cmake with 64-bit linux.

I get a different error when I enable the intel opencl demos. Looks like the build only works for windows.

[ 90%] Built target AppThreadingDemo
make[2]: *** No rule to make target `../Glut/glew32.lib', needed by `Demos/ParticlesOpenCL/Intel/AppParticlesOCL_Intel'. Stop.

Hopefully they'll address this in a configuration for CMake that if your GPGPU isn't OpenGL 4.x ready that they disable some of the configurations, if that is what it takes.

For the NVIDIA issue, did you install the latest NVIDIA CUDA SDK (4.x) and does the CMAKE build system detect its location properly?

We haven't done much testing on the Intel SDK yet, and wait until GPU OpenCL support is done (Ivy bridge)
We replaced glew32 by glew32s under Windows. For now, please do a comparison of the CMakeLists.txt with the AMD version?

Thanks,
Erwin

Same error here( Demos/SharedOpenCL/btOpenCLUtils.cpp:125:12: error: ‘CL_GL_CONTEXT_KHR’ was not declared in this scope)
on archlinux 64bit with Nvidia

I made it compiling by including "CL/cl_gl.h" (removing the #ifdef WIN32 in btOpenCLINclude.h)

cmake output for info:
