I need help trying to compile a simple example for GLFW with MinGW

问题


I am trying to compile an example from GLFW's documentation.

My folder structure for the libraries and source files are:

C:\cpp\

glfw3.dll glfw3dll.a libglfw3.a test.cpp

include\

GLFW\

glfw3.h glfw3native.h

#include <GLFW/glfw3.h>

int main(void)
{
    GLFWwindow* window;

    /* Initialize the library */
    if (!glfwInit())
        return -1;

    /* Create a windowed mode window and its OpenGL context */
    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    /* Make the window's context current */
    glfwMakeContextCurrent(window);

    /* Loop until the user closes the window */
    while (!glfwWindowShouldClose(window))
    {
        /* Render here */

        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

I'm trying to compile it with this command

c:\cpp>x86_64-w64-mingw32-g++ -lglfw3  -Iinclude test.cpp -o test

but I get this error:

c:/users/username/gcc/bin/../lib/gcc/x86_64-w64-mingw32/4.7.2/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lglfw3 collect2.exe: error: ld returned 1 exit status

-v outputs:

回答1:


The order the library as it appears in the command line is important for gcc as well as the library search paths to look in. Try moving -lglfw3 to the end and add the current directory to the search path using -L.

eg.

g++ -Iinclude test.cpp -o test.exe -L . -lglfw3

Edit1: From looking at the verbose status output, it seems libglfw3.a that you have isn't compatible with the mingw gcc you're using. Luckily, the ld linker can work with dll files directly. See if the following works:

g++ -Iinclude test.cpp -o test.exe .\glfw3.dll

The alternative would be to create an import library from glfw3.dll using mingw gcc that you have. This is a bit more involved since you'd need create a .def file followed with a call to dlltool.

Edit2: The mingw gcc you're using is a 64-bit windows compiler. Make sure you're using the correct glfw3 64-bit library and not the 32-bit version. GLFW download section.

I think you have a naming problem. It seems Mingw32 compiler is looking for the library files glfw3.dll, glfw3.a and glfw3.h. The problem is that your library file is named libglfw3.a. Now you need to rename it to glfw3.a so that it can find it. If that still does not work then, you need to rename glfw3dll.a to glfw3.dll.a
