C++ 使用代码块将GLEW链接到SFML项目时出现的问题

因此，我正在尝试编写着色器，并将它们合并到我的OpenGL程序中（我使用SFML 1.6创建有效的OpenGL环境，而不是使用GLUT；我的IDE是代码块；我的卡支持OpenGL 3.1和GLSL 1.3）。然而，我遇到了一个障碍；看起来我需要GLEW来帮助将GLSL着色器合并到我的程序中。因此，我找到了GLEW的源代码，并按照最后一条评论的说明，使用代码块将其编译为静态库（我在c.文件中添加了

#define GLEW_static

，因为我不清楚应该在哪里添加它），因此我现在有四个.a文件：

libglew32.a、libglew32d.a、libglew32mx.a、libglew32mxd.a

我已经告诉我的编译器在哪里可以找到头文件（glew.h、glxew.h、wglew.h），并且我已经告诉链接器在哪里可以找到库（如上），方法是将相关目录添加到设置->编译器和调试器…->搜索目录。在我的项目中，在“构建选项->链接器设置->链接库”下，我还链接了上面四个

执行上述所有操作时，我在尝试调用glewInit（）时遇到以下错误：

对“\u imp\u\u glewInit”的未定义引用

有人告诉我，我需要在包含之前添加

#define GLEW_STATIC

，所以我这样做了，现在我得到了大量未定义的引用”wglGetProcAddress@4“错误（我的程序中唯一一行GLEW代码是

glewInit（）；

）：

我不知所措；所有这些（链接/编译/等等）的技术方面对我来说仍然是新的和令人困惑的

---

为了让GLEW正常工作，我需要做什么，以便将GLSL着色器合并到我的SFML OpenGL项目中？（或者，如果没有GLEW或任何其他外部库，我可以更轻松地实现这一点吗？这太棒了！）

您还需要链接opengl32.lib。链接器抱怨缺少的那些函数是opengl32.dll的一部分，要访问它，需要针对它进行链接。不是在静态库中，而是在最终程序中。从技术上讲，静态库与目标文件的归档不同，即编译阶段的结果。链接到DLL需要在可执行二进制文件的上下文中进行
