codeblock为啥运行不了递归函数

参考技术A codeblock为什么运行不了递归函数
答案如下:因为codeblock运行不了递归函数，海是那样美那样静自然的美。

为啥 glut.h 会在 CodeBlocks 中弹出一堆未定义的引用？

【中文标题】为啥 glut.h 会在 CodeBlocks 中弹出一堆未定义的引用？

【英文标题】：Why does glut.h pop up with a bunch of undefined references in CodeBlocks?为什么 glut.h 会在 CodeBlocks 中弹出一堆未定义的引用？

【问题描述】：

我想在这里理解一些东西。如果我从 OpenGL 游戏编程构建第一个程序并在发布模式下运行它，一切正常。我在 OpenGL 窗口中渲染了立方体。但是，如果我在调试模式下编译和运行，就会弹出 glut.h，其中包含大量未定义的引用。我知道这里出了点问题，我不应该更改库文件，所以我想弄清楚这一点。以下是所有错误：

这里发生了一些奇怪的事情......我没有将 AllCode 链接到任何地方。我在链接器或搜索目录设置中没有任何内容。那么 AllCode 是如何被引用的呢？它从哪里获取这些信息以及如何更改它？

据我了解，我需要让这个东西在调试和发布模式下编译和运行，这样所有错误都得到解决。是我错了吗？

我的系统是 Windows 7 64 位。但是我正在运行 Code::Blocks 13.12 32 位。我已经安装了非 MinGW 版本，然后安装了 MinGW（也是 32 位）并将 Code::Blocks 链接到该版本。使用 MinGW GCC 编译器，g++ for c++，构建为 32 位。

在 MinGW\bin 目录中，我放置了 OpenGL32.dll 和其他 OpenGL dll。进入 MinGW\Include\GL 我已经复制了 OpenGL .h 文件。我在这里做错了吗？

我想了解如何正确设置，以便编译和运行任何 OpenGL 代码，即使它已有 20 年左右的历史。我不知道这样做的正确方法。我会很感激一些建议和帮助。

更新： 所以我找到了一个 libglut32win.a 文件，然后添加它，或者在编译器/链接器设置/其他链接器选项下输入 -lglut32win，阻止 glut 弹出错误。相反，我得到了这些：

那么这是什么意思呢？

【问题讨论】：

我现在忘记了它的确切细节，因为它是很久以前的事了。但是，当我第一次在 windows 下使用 C::B 尝试 Glut 时，我遇到了（我认为）类似的问题（可能也是 linux，我忘记了）我的解决方案是下载并使用 glut 替代品 freeglut。你可以在这里找到它：freeglut.sourceforge.net 编辑： 刚刚检查了 CodeBlocks\MinGW\lib 文件夹 - 没有文件名 libglut.a - 这就是我安装 freeglut 的原因 - glut 的 lib 文件不是t 可用于 C::B 安装。 （可能是 minGW 的事情）无论如何，freeglut 对我有用。不要忘记链接它！

【参考方案1】：

这些是您未链接到库时收到的标准错误。您的 Release 构建设置可能有一个链接到 glut 的条目，但 Debug 构建设置没有。如果您希望一个库在 Release 和 Debug 中都链接，您需要在项目级别而不是构建级别添加它。
