GLFW 未定义参考

Question

我正在尝试在项目上使用 GLFW，但是当我编译它时，我收到很多未定义的引用错误，而其中许多错误位于库文件（libglfw.a）中。 我尝试了两种方法，编译库并下载它，但没有成功。 我正在使用在 Windows 7 32 位上的 netbeans 上运行的 MinGW 和 MSYS。 GLFW版本是2.7.3；

这些是错误：

Answer 1

难道你不需要链接 OpenGL 库吗？我没有看到 libGL 或 libGLU。我知道 glClear 位于 libGL 或 libGLU 中。

Answer 2

在链接器中，在 Windows 中，MinGW： -lglew32 -lglfw3 -lopengl32 -lglu32 -lgdi32

将库和包含文件放入 MinGW 中，将 dll 和 exe 放入 Windows 系统文件夹中。

Answer 3

就我而言，问题有所不同。我正在链接 opengl32，但仍然收到错误。问题出在库顺序上：glfw 必须在 opengl32 之前链接。

在我的例子中，它位于 Code::Blocks IDE 的“链接库”列表框中，但在 NetBeans 或命令行中它会类似。

Answer 4

我得到的错误

undefined reference to `__imp_glfwInit'

在我更改为glfw-3.3.2.bin.WIN64（64位glfw）后解决了问题
