ios - MonoTouch 第 3 方库适用于 4.2 但不适用于 5.0

Question

我有一个第三方库，我终于可以在我的 MonoTouch 应用程序中使用它了。但是，当我将 SDK 设置为 4.2 时，它只会为模拟器编译。如果我将它设置为 5.0，链接器将失败。它将编译为实际设备的 5.0。它要求的 gcc_s.10.5 是什么，它应该位于何处？

libgcc_s 可能 libGrabbaDriver.a 的依赖项，您正在将您的 MonoTouch 项目与之链接。

 ld: library not found for -lgcc_s.10.5

该库的名称​​可能已更改，即它在我的 iOS 5.1 系统上不相同。

 /Applications//Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/usr/lib/libgcc_s.1.dylib

从那里我假设你需要:

• 将您的应用程序与较新的库链接(希望没有内部更改)；

• 重建 native 库以将其与正确(较新)版本的 libgcc_s
