Source code:

#include <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 */
        glClear(GL_COLOR_BUFFER_BIT);

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

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

    glfwTerminate();
    return 0;
}

Spaces in arguments matter!

Here:

-Wl, -BStatic

Try removing the extra space:

-Wl,-BStatic

The reason is that the part after -Wl, is the argument passed to the linker.

See questions like I don't understand -Wl,-rpath -Wl, and `-Wl,` prefix to compiler flag

OK, I tried deleting space but it didn't fix the problem. I was getting error:

c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: unrecognized option '-BStatic'
c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: use the --help option for usage information
collect2.exe: error: ld returned 1 exit status

I was going through the gcc and linker documentation, but while not knowing how it works, finally tried and it worked:

g++ -I<pathHeaderFolder> Application.cpp -Wl,<pathLibraryFolder>libglfw3.a -lglu32 -lopengl32 -lkernel32 -luser32 -lgdi32 -lws2_32

I don't really know why it worked, but I read in the linker documentation that if passing options to the linker it must be done through the -Wl

Also, adding "-L" before library path for linker

-Wl,-L<pathLibraryFolder>libglfw3.a

was giving me an error like I didn't link a library. I don't know why

But anyway it worked, so thanks a lot for help! I wouldn't come up that spaces in arguments matter
