Hello! I am having this compiler error “undefined reference to glActiveTexture
” and I have no idea why this is happening. I should start of with saying that I am new to opengl, but it appears that every other function I have tried works just fine, I have been able to create a context and draw multiple images using functions such as “SDL_GL_CreateContext
”, “glBindTexture
”, “glTexCoord2f
” etc.
these are my includes:
#include <GL/gl.h>
#include <GL/glext.h>
My CMakeLists.txt
looks pretty much like this:
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_FLAGS "-DGL_GLEXT_PROTOTYPES -std=c++11")
set(SDL2_INC_DIR "C:/SDL2_64/include")
set(SDL2_LIB_DIR "-LC:/SDL2_64/lib")
set(SDL2_LIBS "-lSDL2main -lSDL2 -lSDL2_image -lSDL2_mixer")
set(GL_LIBS "-lglu32 -lopengl32")
include_directories(.)
include_directories(src)
include_directories(untitled ${GL_INC_DIR} ${SDL2_INC_DIR})
target_link_libraries(untitled -lmingw32 ${SDL2_LIBS} ${SDL2_LIB_DIR} ${GL_LIBS})
Any ideas?
