mono - 无法在 OS X 中的 MonoDevelop 3.0 上构建任何 MonoMac 示例

Question

我刚刚在 OS X (10.7.2) 中全新安装了 MonoDevelop 3.0，然后对 MonoMac 进行了 Git check out 。 .我无法构建 MonoMac 存储库中包含的任何示例，每次在输出显示构建成功后我都会收到相同的错误:

Build failed. Object reference not set to an instance of an object

完整示例构建输出:

我在这里做错了什么？

这是一个已知问题。问题是 MonoDevelop 在您的系统上找不到 MacOSX sdk(可能您使用的 Xcode 版本早于 4.3？)。

我正在为 MonoDevelop 3.0.2 修复这个问题
