问题
I was trying to build an opengl program on qt creator, installed on my mac, with osx 10.9. I got several warnings on glut functions about its deprecation in osx10.9, a sample error message is like:
'glutInit' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations] glutInit(&argc, &argv); ^
I wonder if GLUT.h is not usable anymore in osx10.9? According to some other posts, it is said that as long as we change "OS X Deployment Target" back to OSX10.8, then it works. How to do so in qtcreator? Thank you!
回答1:
You can still use it in 10.9. They're sending you a pretty strong signal that they want you to stop, though...
You can disable those warnings with the -Wno-deprecated-declarations compiler option.
There's also some difficulties including the right headers if you're trying to use GL3 level features, because you need to include gl3.h for that, while glut.h includes gl.h, which causes additional complaints about possible conflicts while building. The somewhat hacky workaround I found for this is to prevent glut.h from including gl.h by defining the header guard:
#include <OpenGL/gl3.h>
#define __gl_h_
#include <GLUT/glut.h>
Then, for using GL3+ level features, you need to specify that with an additional flag to glutInitDisplayMode():
glutInitDisplayMode(... | GLUT_3_2_CORE_PROFILE);
It looks like it's probably time to start using GLFW. I never used GLUT for anything serious, but it was always very convenient for small demos/tests.
