I'm starting a c++ project using SDL 2 and GLEW 2.0 which I want to compile by using g++ in the command line (I'm trying to avoid IDE(s) like Visual Studio or Code::Block). I was able to create a basic opengl triangle in the GameEngine class but once I added the Sprite class, I'm getting the following error :

g++ ./src/main.cpp ./src/gameEngine/GameEngine.cpp ./src/gameEngine/Sprite.cpp ./src/gameEngine/Sprite.h ./src/gameEngine/GameEngine.h -I./lib/SDL2_32/include -I./lib/GLEW2_32/include -L./lib/SDL2_32/lib -L./lib/GLEW2_32/lib -w  -std=gnu++11 -lmingw32 -lSDL2main -lSDL2 -lOpenGL32 -lglew32 -o ./bin/main

It seems that there's a linking error so that Sprite cannot access glew's definitions. I tried every single solution posted online but most of them concerns Microsoft visual studio or Code::Block and not the commandline.. Please help!

  • Are you sure they are available in the lib you are linking against? Are you sure you are not missing a lib? – Ceros Sep 16 '16 at 20:45
  • It seems that the "-lglew32" flags had to be in front of the "-lOpenGL32" flag.. well it seems to be the answers because my program compiles and runs now – HEYIMFUZZ Sep 16 '16 at 21:19
