@dalexsoto @rolfbjarne ?

This is strange, every invocation of clang crashes.

Does this also happen if you try with a new project created from a template?

[Abhirasmanu-Trimble]

Hello, I was able to reproduce the problem with template project also. I have attached the build log BuildLogs.zip. Build is started using dotnet build command from command line like this: dotnet build /p:IsPublishing=true;ArchiveOnBuild=true iOSApp1.csproj -c:Release -f:net8.0-ios -p:RuntimeIdentifier=ios-arm64 /p:ServerUser=server-user /p:ServerAddress=server-ip-address -bl:build.binlog -fl -flp:logfile=build.log;verbosity=diagnostic

When building the same project from visual studio I get a different error complaining about missing install_name_tool. Attached the build log from vs visual_studio_build_log.zip install_name_tool name is installed and available in path. When I "type install_name_tool" I get "install_name_tool is /usr/bin/install_name_tool" in the OSX terminal.

@Abhirasmanu-Trimble do you have this file on your Mac:

~/Library/Preferences/Xamarin/Settings.plist

and if you do, can you try deleting it to see if that fixes the problem?

[Abhirasmanu-Trimble]

Hello @rolfbjarne,

I do not have this file on my mac.

[rolfbjarne]

@Abhirasmanu-Trimble can you run the following in a terminal on your Mac, and paste the output here:

xcode-select -p
sudo xcode-select -s /Applications/Xcode.app

and then try again?

[Abhirasmanu-Trimble]

Hi @rolfbjarne, FYI ~ % xcode-select -p (Result)->/Applications/Xcode.app/Contents/Developer

I still get the same clang error in build

[rolfbjarne]

@Abhirasmanu-Trimble does the project build if you build it from the command line on the Mac? If not, can you attach the corresponding binlog?

[Abhirasmanu-Trimble]

@rolfbjarne , the build does work when directly built form mac command line (ssh also works). I could not create binlog or daignostic log since the the parameters are not recognized. Detailed log is seems to be generated automatically (no idea why). I have attached the default msubild.log here.msbuild.zip This was command I ran from the command line. dotnet publish -r:ios-arm64 /p:BuildIpa=true -c:Release -f:net8.0-ios -fl -flp:loggile=build.log;verbosity=diagnostic -bl:build.binlog

@Abhirasmanu-Trimble does it still fail from Windows if you try with a new project from a template?
