General / OpenGl vbo, vertex arrays with sfml

« on: April 02, 2017, 12:50:05 am »

I'm fairly new to sfml and opengl. I'm stuck with creating vbo and vao with glGenBuffers(). Those functions are undefined until I include glew.h. I read that Sfml include glew by itself and it is not recommended to include it second time. I tried both ways - it is either undefined or linking errors. All examples I found use glBegin, glEnd blocks. Can someone point me at the right direction where I can learn about creating vbo, vao, shaders with Sfml? thank you.

General / Linking issue in VS

« on: March 30, 2017, 04:55:43 pm »

I am working on a large game project, and I chose to use sfml for this. I downloaded sdk, managed to build it using cmake and mingw. Then I tried to configure the project in VS community 2017 as instructed in your tutorials. And no matter witch dynamic or static libraries I use I get the same error. I tried releasing in 32 or 64 modes with the same result. I so do not want to use sdl2. Please help!
