The build is failing:

CSharpTypePrinter.cs(612,65): error CS1001: Identifier expected [/home/runner/work/CppSharp/CppSharp/src/Generator/CppSharp.Generator.csproj]

@tritao How would i regenerate the bindings for the cpp parser

[tritao]

Check https://github.com/mono/CppSharp/blob/main/src/CppParser/ParserGen/ParserGen.cs

And might want to extract https://github.com/mono/CppSharp/releases/download/CppSharp/headers.zip into your bin folder to generate for all supported platforms.

[kumja1]

@tritao strings are typically utf16 in native code correct? or are they different depending on the platform(like wchar_t is utf32 on linux)

[tritao]

Yes they can be different depending on the platform or program.

It can be set as an option: https://github.com/mono/CppSharp/blob/main/src/Generator/Options.cs#L189
