OS X: Exception in `CLWProgram::CreateFromSource` about "<angled> includes"

I get this error log:

Changing the angled includes in bvh.cl to:

#include "../FireRays/src/kernel/CL/common.cl"

fixes the error. This is the last issue I ran in to, the program runs now :-)

Hi ericwa,

What is your working directory? Demo app requires working directory to be SDKROOT/App

[ericwa]

Can you try using --embed_kernels premake option? (You'll have to revert angle brackets back to use it I guess). That's most likely due to incorrect handling of includes in Apple CL compiler.

OK, I tried:

• reverted to angle brackets
• ./Tools/premake/osx/premake5 xcode4 --embed_kernels
• working directory in Xcode set to SDKROOT/App

and everything worked. Running premake again without --embed_kernels, the OpenCL compile error about angle brackets returns.
