Assuming that you've saved your MathGL program in a file named mgl_ex1.cpp, this is how you can build it: 1 g++ mgl_ex1.cpp -o mgl_ex1 -lmgl. The packages necessary for C/C++ compilation should be installed. Copy assimp.dll from build/code/Release to dlls folder of our Sample project. I mostly use GLUT/FreeGLUT, and each example project includes FreeGLUT header and library files in it for MinGW environment. In most Linux distributions the development files for OpenGL are contained in a dedicated package, that is usually a dependency for a desktop application development meta-package. As such, the part of your application that does rendering is platform independent . Lighthouse 3D offers direct links to their tutorials covering the spectrum from GLUT to GLSL, computer graphics math to stencil shadows. When you have successfully built Assimp binaries, you can do the following steps: Copy assimp.lib from build/code/Release to lib folder of our Sample project. "Hello Triangle" OpenGL 4 Up and Running Anton Gerdelan. It works like this: //Create a variable to store the handle int ObjectHandle; //Create the object GL.GenObjects (1, &ObjectHandle); //Then pass it to a function that uses it GL.SomeFunctionThatUsesThisObject (ObjectHandle); This little piece of code is a workflow you'll frequently see when working in OpenGL.
