尝试在Mac上编译GLFW时GLFW上的链接器错误

Linker error on GLFW when trying to compile GLFW on Mac

我正在尝试在带有xcode的Mac上使用glfw 2.7.5,但是出现以下错误:

我已经阅读了使用 GLFW 和 XCode 的问题:无法编译和互联网上的其他几个链接,但我找不到解决方案。

我已经设置了Cocoa框架,OpenGL框架和libglfw.a(我使用"sudo make cocoa-install"编译),在我设置的链接器标志中-lgflw,我正在为32位英特尔构建。起初我正在为 64 位构建,但我认为 GLFW 在 Mac 上还不支持它(我收到操纵杆文件错误),当我编译为 32 位时错误会发生变化,它找不到我正在使用的功能。知道我能做些什么来解决这个问题吗?

很可能您已经为 64 位构建了 libglfw.a,因此当您尝试在 32 位应用程序中使用它时会出现链接错误。您可以重建 32 位的 libglfw.a(或作为"胖"32 位和 64 位库),也可以将应用程序构建为 64 位。

请注意,在最新版本的 Mac OS X 和 Xcode 中,gcc 默认构建 64 位代码,因此您需要在命令行上指定-m32以获取 32 位代码。在实践中如何执行此操作取决于 libglfw.a 的 makefile - 很可能有一个 ARCH 或其他符号,您可以在命令行上指定它们来强制 32 位构建。
