I downloaded from the official website oglpg - 8 th - edition folder, add in VS2015 contain catalog oglpg - 8 th - edition \ include, also add library catalog oglpg - 8 th - edition \ lib, and then copy the OpenGL programming guide the eighth edition of the first chapter of triangles. The CPP, also add in the project LoadShaders. CPP,

Whether oglpg - 8 th - edition freeglut_static_2010. Lib and libcmtd lib have conflict? I use VS2010 libcmtd lib 2015, replacing the mistake turned out to be a 52. How to do?

If trouble you look at the great god, solves the problem, I will appreciate it very much! And I will put the specific configuration method writes his own blog, to those who use VS2015 for your reference,

CodePudding user response:

Try the libcmtd. Lib this library ignored

CodePudding user response:

Vs must use Windows console project, specify the library file directory, because of the glut, glew are many tags, the window header file can't disorderly, such as two glut. J h, death,
