【问题描述】：

源代码：

#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;

编译器：

g++ (MinGW.org GCC Build-20200227-1) 9.2.0

我尝试过的命令和错误：

【参考方案1】：

参数中的空格很重要！

这里：

-Wl, -BStatic

尝试删除多余的空间：

-Wl,-BStatic

原因是-Wl,之后的部分是传递给链接器的参数。

查看I don't understand -Wl,-rpath -Wl, 和`-Wl,` prefix to compiler flag 等问题

【参考方案2】：

好的，我尝试删除空间，但没有解决问题。我收到错误：

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

我正在浏览 gcc 和链接器文档，但虽然不知道它是如何工作的，但最终尝试并它工作了：

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

我真的不知道它为什么起作用，但我在链接器文档中读到，如果将选项传递给链接器，则必须通过 -Wl 完成

另外，在链接器的库路径前添加“-L”

-Wl,-L<pathLibraryFolder>libglfw3.a

给了我一个错误，就像我没有链接库一样。不知道为什么

但无论如何它都有效，非常感谢您的帮助！我不会在争论中提出空格问题
