Question

使用MinGW编译GLFW的一个简单示例，我需要帮助。

c++windowsg++mingwglfw

7

我正在尝试编译GLFW文档中的示例。

我的库和源文件的文件夹结构如下：

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;
}

我试图使用以下命令进行编译

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

但我收到了以下错误提示：

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输出：

我认为您遇到了命名问题。看起来Mingw32编译器正在寻找库文件glfw3.dll、glfw3.a和glfw3.h。问题在于您的库文件被命名为libglfw3.a。现在您需要将其重命名为glfw3.a，以便它能够找到它。如果仍然无法正常工作，则需要将glfw3dll.a重命名为glfw3.dll.a。

- Juniar

不，那完全是错误的。因为mingw只是gcc的一个移植版本，所以它的行为就像gcc一样。这意味着-l开关会自动在查找时添加前缀“lib”。libglfw3.a的命名是正确的。 - greatwolf

在命令行中库的顺序及其搜索路径对于gcc和库是非常重要的。尝试将-lglfw3移到最后，并使用-L将当前目录添加到搜索路径中。

例如：

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

编辑1：从冗长的状态输出中看，似乎你所拥有的 libglfw3.a 与你正在使用的 mingw gcc 不兼容。幸运的是，ld 链接器可以直接处理 dll 文件。试试以下方法：

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

另一种选择是使用您拥有的mingw gcc从glfw3.dll创建一个导入库。这需要更多的操作，因为您需要创建一个.def文件，然后调用dlltool。

编辑2: 您正在使用的是64位Windows编译器的mingw gcc。确保您使用的是正确的glfw3 64位库，而不是32位版本。GLFW下载页面。
