Is this the problem from Perl side

Yes. In order to call the functions in your DLL, you need to supply Win32::API with the name of the function to call--but it has to be the name as exported, not the internal C++ method name.

Because a single class can have multiple methods with the same name but different nos and/or types of parameters, the names have to be "mangled" for export. Encoded within those mangled names is the number and types of the parameters the functions (methods) expect.

See Name mangling for more info. It doesn't mean that calling C++ methods is impossible with Win32::API--just makes it sufficiently hard that no one will bother unless they absolutely have no choice. Eg. They have a C++ DLL that they must use, but no source.

You'd be better of investigating Inline::CPP.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
