问题详情 #

1. 库编译适配错误：引用Ubuntu 22.04已弃用的libdl.so #

Windows环境测试正常，但在Azure Unix环境中启动时抛出以下错误：

System.DllNotFoundException: Unable to load shared library 'libdl.so' or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable: 
      /workspace/RestAPI/bin/Debug/net7.0/runtimes/linux/native/libdl.so.so: cannot open shared object file: No such file or directory
      /usr/share/dotnet/shared/Microsoft.NETCore.App/7.0.14/libdl.so.so: cannot open shared object file: No such file or directory
      /workspace/RestAPI/bin/Debug/net7.0/libdl.so.so: cannot open shared object file: No such file or directory

      /workspace/RestAPI/bin/Debug/net7.0/liblibdl.so: cannot open shared object file: No such file or directory

通过创建软链接临时解决，但并非理想方案：
sudo ln -s /usr/lib/aarch64-linux-gnu/libdl.so.2 /usr/lib/aarch64-linux-gnu/libdl.so

2. libmip_dotnet.so加载失败 #

解决上述问题后，出现新的加载错误：

System.ComponentModel.Win32Exception (0x80004005): LoadLibrary failed for: [/workspace/RestAPI/bin/Debug/net7.0/libmip_dotnet.so]
         at Microsoft.InformationProtection.Utils.SafeNativeMethods.LoadLibrary(String dllToLoad)
         at Microsoft.InformationProtection.Utils.Loader.LoadDlls(String dllFolder, String dllName, String[] dllDependencies)
         at Microsoft.InformationProtection.MIP.Initialize(MipComponent mipComponent, String path)
         at Microsoft.InformationProtection.MIP.CreateMipContext(MipConfiguration mipConfiguration)

尝试GitHub上建议的C代码片段排查，仍报错：

err = ./libmip_dotnet.so: cannot open shared object file: No such file or directory
