MonoTouch第三方庫與4.2但不是5.0兼容

Question

我有第三方庫，我終於在我的MonoTouch應用程序中工作。但是，只有在將SDK設置爲4.2時，纔會爲模擬器進行編譯。如果我將它設置爲5.0，鏈接器將失敗。它將編譯爲5.0爲實際設備。它要求的gcc_s.10.5是什麼，它應該放在哪裏？

Answer 1

的答案正確的（新）版本已經是聯繫在一起的。同樣的問題也發生在不同的項目上。最後，我從Snow Leopard升級到Lion，升級到最新的xcode，現在它全部正常。

Answer 2

看起來您的系統處於不一致的狀態。

MonoTouch不嘗試鏈接libgcc_s，並且bitofgoogling顯示它根本不與MonoTouch相關。

我會嘗試卸載並重新安裝的Xcode（您可能需要重新安裝的MonoTouch過，因爲Xcode中可能會在某些情況下將其刪除）：

Answer 3

libgcc_s是可能其中你的libGrabbaDriver.a依賴將您的MonoTouch項目與。

ld: library not found for -lgcc_s.10.5 

該庫威力的名稱發生了變化，即它不是在相同的iOS我5.1的系統。

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

從那裏，我會假設你需要：

• 與新的庫鏈接您的應用程序（希望沒有內部的變化）;

• 重建機庫上面是對的方法與libgcc_s
