Try to compile OpenGL 4 Helloworld in CLion + CMake + MinGW on Windows. & ldquo; undefined reference to `_imp____glewCreateShader '& rdquo; Errors

  • What is an undefined reference/unresolved external symbol error and how do I fix it? 27 answers

Googling aroung told me it was "wrong VS libraries" but when tried to use glew-1.5.4-mingw32 and libgluew32.a instead of glew32.lib (and same done to glut) nothing changed.

main.cpp got from project on VS2012, attaching same libs, so it may not be wrong.

Some files I use to make:


cmake_minimum_required(VERSION 2.8.4)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

add_executable(HelloGL main.cpp)

set(LIBS_DIR D:/libs)

set(GLEW_ROOT_DIR ${LIBS_DIR}/glew-1.5.4-mingw32 )
set(GLUT_ROOT_DIR ${LIBS_DIR}/glut-3.7.6-src/glut-3.7.6 )


set(GLEW_LIBRARY ${GLEW_ROOT_DIR}/lib/libglew32.a)
set(GLUT_LIBRARY ${GLUT_ROOT_DIR}/lib/glut/libglut32.a)

include_directories( ${GLEW_INCLUDE_DIRS} ${GLUT_INCLUDE_DIRS} )

target_link_libraries(HelloGL ${GLEW_LIBRARY} ${GLUT_LIBRARY} )

Try adding this line to your CMakeLists.txt:


It seems that you are trying to link GLEW statically but you didn't define GLEW_STATIC
