Problem using ida_srclang

I want to be able to parse type decls that can include template types. I stumbled upon ida_srclang as a potential way to do that, but I cannot get it to work - apparently, there is a lot more setup required than the documentation reveals. Here is what I am seeing on a simple example:

My host environment is Windows 11 and I have Visual Studio 2022 installed. If anyone can tell me what magic is needed to get this working, I’d appreciate it. Thanks.

I figured out the following will enable the parser to run:

ida_srclang.set_parser_argv(“clang”,“-x c++ -target x86_64-pc-win32”)

However, this doesn’t work like tinfo_t.parse - it expects a fully compiable c++ snippet, so it winds up being useless for my needs.
