Xamarin.ios Monotouch应用程序无法使用iOS SDK 4.3与Mobclix SDK链接

我在我的应用程序中使用Mobclix做广告，并且我已经使用btouch创建了mono绑定，我已经成功使用了一段时间。我还向我的项目添加了额外的GCC标志，以便链接到Mobclix.a库

不幸的是，在升级到iOS SDK 4.3、MonoTouch 3.2.5和MonoDevelop 2.4.2之后，在构建iOS模拟器时，我无法再链接我的应用程序。我收到以下错误消息：

我理解的是，MaMclix库使用C++（特别是C++异常），而MyLoTou/MaunDeC++中的链接器步骤不与C++标准库链接，或者启用C++异常。我不明白为什么只有在为模拟器构建时才会发生这种情况，或者为什么在我更新MonoTouch和iOS SDK之前不会发生这种情况

有人知道怎么解决这个问题吗

我尝试将-fexceptions和-lstdc++添加到我的-gcc_标志中，但没有任何帮助。

新的MonoTouch Alpha 2有一个新的“额外参数”标志“-cxx”，它将强制链接到g++。试试看。

不幸的是，这没用。我可以看到它在链接时使用了g++，但我得到了相同的错误消息（未定义的符号“\uuu Unwind\u Resume”）。我通过在gcc_标志中添加-lgcc_eh成功地解决了这个问题。我是否使用-cxx并不重要。这也适用于稳定版本的MonoTouch。
