Invalid argument when compiling GLFW code?

Question

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;
}

Compiler:

Answer 1

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
