Catalina MacOS 上的 mono 运行时异常

Question

I have an application that is made by .NET and i use mono 6.4.0.198 (i use the newest mono so the app is compatible with Catalina MacOS ) to run it on the Mac machine, on my machine the mono is installed so the app works很好，但是当我在其他 Mac 上运行该应用程序时，它返回以下异常

clearly its a missing dll libmono-native-compat.dylib i added this dll at the application resources alongside other dlls but the app still returning the same missing dll exception, how i can direct mono to dll so i would fix this problem

Answer 1

在我决定授予我的 /private/tmp 文件夹权限之前，我在安装 macOS Catalina 时遇到了很多错误。 似乎所有应用程序现在都可以正常工作。 我不知道这是不是你的情况，但以防万一试试这个：

sudo chmod 777 /private/tmp

Answer 2

我解决了这个问题

创建一个名为fix.config的文件，它包含以下 XML

<configuration>
    <dllmap dll="System.Native" target="libmono-native-compat.dylib" os="!windows" />
    <dllmap dll="System.Net.Security.Native" target="libmono-native-compat.dylib" os="!windows" />
    <dllmap dll="System.Security.Cryptography.Native.Apple" target="libmono-native-compat.dylib" os="osx" />
</configuration>

我将 XML 中提到的三个 dylib 复制到路径Application/MyApp.app/Contents/lib

然后在构建脚本中，我将以下命令添加到工具mkbundle

--config $SETUP_DIR/fix.config和设置路径是我创建我的.pkg文件的路径

注意：我使用的是 mono 版本6.4.0.198
