c++ - 操作系统 : Symbols not found for architecture i386

Question

我有以下使用 C++ 和 OpenGL 的生成文件。它正在编译，所以我添加了 -m32 行以尝试让它在 x86_64 中编译。现在我遇到了同样的错误，但它说的是 i386。

我该怎么做才能编译这个程序？

我正在运行 OSX 10.8，以防万一。

谢谢大家

您正在为 MacOS X 编译，所以不要使用 X11，而是使用 native OpenGL 框架；编译器/链接器选项是 -framework OpenGL。

你的错误源于你可能使用了预编译库文件，甚至没有为你的特定版本的 MacOS X 编译，甚至根本没有编译。没有编译器开关可以帮助您。
