Getting UnauthorizedAccessException on output directory

[JordyDew]

While executing the following command, I get an UnauthorizedAccessException for the output directory (-o flag): D:\Users\jordy\Downloads\liblouisutdml-2.10.0-win32\include\liblouis> ClangSharpPInvokeGenerator -f .\liblouis.h -n DewSystems.LibLouis -o .\test

The stack trace is the flowing:

                            
Unhandled exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

I tried executing this command in a normal command prompt and a shell with elevated rights (administrator rights). Twice the same result.

Could you please try specifying an output file and not simply a directory?

The generator looks to be in single file mode, in which case I believe -o is required to be a file path. It works as a directory for -c multi-file (where you get a type per file).

I will look at improving the handling or error message here to improve the experience.

The handling here is done by System.CommandLine now.
