MonoTouch第三方库与4.2但不是5.0兼容

Question

我有第三方库，我终于在我的MonoTouch应用程序中工作。但是，只有在将SDK设置为4.2时，才会为模拟器进行编译。如果我将它设置为5.0，链接器将失败。它将编译为5.0为实际设备。它要求的gcc_s.10.5是什么，它应该放在哪里？

Answer 1

的答案正确的（新）版本已经是联系在一起的。同样的问题也发生在不同的项目上。最后，我从Snow Leopard升级到Lion，升级到最新的xcode，现在它全部正常。

Answer 2

看起来您的系统处于不一致的状态。

MonoTouch不尝试链接libgcc_s，并且bitofgoogling显示它根本不与MonoTouch相关。

我会尝试卸载并重新安装的Xcode（您可能需要重新安装的MonoTouch过，因为Xcode中可能会在某些情况下将其删除）：

Answer 3

libgcc_s是可能其中你的libGrabbaDriver.a依赖将您的MonoTouch项目与。

ld: library not found for -lgcc_s.10.5 

该库威力的名称发生了变化，即它不是在相同的iOS我5.1的系统。

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

从那里，我会假设你需要：

• 与新的库链接您的应用程序（希望没有内部的变化）;

• 重建机库上面是对的方法与libgcc_s
