different errors using XCode and make. similar issues with computeShaderTextureExample macos 13.6.4, XCode 15.2, apple silicon

d@zen computeShaderParticlesExample % make RunRelease

Well compute shader is openGL4.3, and macOS is stuck at 4.1... for that reason it's removed from the releases: https://github.com/openframeworks/openFrameworks/blob/c11edeffb5dbd6a19d88eb4687e8ddd03e7820ca/scripts/dev/create_package.sh#L312-L316 Do you mean a better error should be issued if openGL > 4.1 is requested on macOS? or should setupShaderFromFile() alarm if GL_COMPUTE_SHADER when #ifdef OF_TARGET_MAC?

what would be the ideal behaviour?

Yes, thanks for the reminder @artificiel. Definetly it can be handled better, at least ofLogError but maybe std::exit with a message if the requested openGL version is higher than the system can provide. edit: in ofCreateWindow
