    The page you linked provides libraries for a lot of compilers including MinGW 32 and 64 bit.

    If you can't use any of them, the compile the library yourself.

    I right click on the project and add the whole GLFW folder.

    The Qt recognize the function so everything is good. I click on rebuilt all projects

    But when I try to built the program I get the following error:

    1.PNG

    And when I push the run button I get the a loads of errors

    2.PNG

    I use the code from link here.

      GLFW already provides a mean to build their library. Use it.

        And who to built it. I just find the way to use it in VS.

          Please, read the documentation of the libraries you want to use. It's explained right in their website.

            just another think link somebody says

            LIBS += -LC:\Qt\5.13.0\mingw73_64\lib\libQt5OpenGL.a -lopengl64
            

            It should work but it does not work for me

              Other thing is that at glfw\lib-mingw-w64 there is 3 files

              glfw3.dll
              libglfw3.a
              libglfw3dll.a

              these are libarys so I assume that I could include that so right click add external libary I add: libglfw3.a

              .pro file

              TEMPLATE = app
              CONFIG += console c++11
              CONFIG -= app_bundle
              CONFIG -= qt
              
              SOURCES += main.cpp
              
              
              INCLUDEPATH += C:\glfw\include
              
              win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../../glfw/lib-mingw-w64/ -lglfw3
              else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../../glfw/lib-mingw-w64/ -lglfw3d
              else:unix: LIBS += -L$$PWD/../../../../glfw/lib-mingw-w64/ -lglfw3
              
              INCLUDEPATH += $$PWD/../../../../glfw/lib-mingw-w64
              DEPENDPATH += $$PWD/../../../../glfw/lib-mingw-w64
              

              So it looks good but when I try to build the program I get errors

              :-1: error: cannot find -lglfw3d
              :-1: error: collect2.exe: error: ld returned 1 exit status

                @bence said in Qt GLFW and GLEW setup:

                error: cannot find -lglfw3d

                I don't know whether it would give rise to that error message, but I do not see either a .dll or a .a having that trailing d in its name. When using MSVC, debug libraries have a d on the end of their name, but I don't think that is the convention when using gcc/mingw. So are you using a linker line designed for MSVC with a build using MinGW?

                    @bence
                    The 3 unreferenceds you list come from WinGDI. You would need to link against something link Gdi32.lib for these, which I suspect you are not doing. Or, I don't know, those leading __imp_s might indicate you are still somehow trying to link against MSVC libraries.

                    In fact I even see a stackoverflow post covering this for GLFW MinGW link error, which you should read through and follow. It says MinGW has a library libgdi32.a for these.

                      The 3 unreferenceds you list come from WinGDI. You would need to link against something link Gdi32.lib for these, which I suspect you are not doing. Or, I don't know, those leading __imp_s might indicate you are still somehow trying to link against MSVC libraries.

                      In fact I even see a stackoverflow post covering this for GLFW MinGW link error, which you should read through and follow. It says MinGW has a library libgdi32.a for these.

                      @JonB But there is no Gdi32.lib file in the folder

                      And if I just use the following code

                      int main(void)
                      {
                          if (!glfwInit())
                              return -1;
                          return 0;
                      }
                      

                      It still not woriking

                          The only thing that I did is I add two file. I assume that I just have to do that.

                          .pro file

                          TEMPLATE = app
                          CONFIG += console c++11
                          CONFIG -= app_bundle
                          CONFIG -= qt
                          
                          INCLUDEPATH += C:\glfw\include
                          
                          SOURCES += main.cpp
                          
                          win32: LIBS += -L$$PWD/../../../../glfw/lib-mingw-w64/ -lglfw3
                          
                          INCLUDEPATH += $$PWD/../../../../glfw/lib-mingw-w64
                          DEPENDPATH += $$PWD/../../../../glfw/lib-mingw-w64
                          
                          
                          win32: LIBS += -L$$PWD/../../../../MinGW/lib/ -lgdi32
                          
                          INCLUDEPATH += $$PWD/../../../../MinGW/include
                          DEPENDPATH += $$PWD/../../../../MinGW/include
                          
                          win32: LIBS += -L$$PWD/../../../../MinGW/lib/ -lopengl32
                          
                          INCLUDEPATH += $$PWD/../../../../MinGW/include
                          DEPENDPATH += $$PWD/../../../../MinGW/include

                            It looks like you are mixing two different MinGW installations.
