c# - 已编译的单声道缺少默认 .NET 库 - 未定义或导入 System.Object

Question

我已经按照位于此处的指南在 OS X Mavericks 上编译了单声道:http://www.mono-project.com/docs/compiling-mono/mac/

现在，当我使用 xbuild 编译我的应用程序时，出现以下错误:

当我在 OS X 上使用单声道安装程序时，我从未收到任何这些错误。

(我正在构建单声道，因为我正在向未完成的 .NET 框架添加功能)

运行 autogen.sh 的结果:https://gist.github.com/Geesu/149332f3f877c891d387运行 make 的结果:https://gist.github.com/Geesu/4296f7d4c6c368d6986d

如果有类似这样的警告:

/lib/mono/4.5/Microsoft.Common.targets:  warning : Unable to find framework corresponding to the target framework moniker '.NETFramework,Version=v2.0'. Framework assembly references will be resolved from the GAC, which might not be the intended behavior.

您可以在命令行上覆盖 .NET Framework:

xbuild /p:TargetFrameworkVersion="v4.0"

您可以更改您的解决方案:

<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
