I finally managed to get to matrix3. However, there is a problem so far.
After the build completed successfully, I cannot run mrview.
mrview mrview: [WARNING] unable to determine OpenGL version - operation may be unstable if actual version is less than 3.3 mrview: [ERROR] GLSL log [vertex shader]: ERROR: 0:1: '' : version '330' is not supported ERROR: 0:1: '' : syntax error #version ERROR: 0:2: 'layout' : syntax error syntax error mrview: [ERROR] error compiling OpenGL vertex shader ID 1 QWidget: Must construct a QApplication before a QPaintDevice Abort trap: 6
However it is not true that I have OpenGL less than 3.3.
My OpenGL extension Viewer 4.4 let the test pass for OpenGL 4.0 but not higher.
I have MacOSX 10.9.5 and a graphic card AMD Radeon HD 6750M 1024 MB.
Here https://support.apple.com/en-us/HT202823 it says that this graphic card should even support openGL 4.1.
Xcode installed is version 6.2 which should correspond to OSX 10.9.5.
What should I do?
Thanks for any help!
