Question

I have Linux code and I want to port it to Windows. The code uses Glib::ustring, but I want to replace all the strings to std::wstring for testing purposes.

Is there a way to define all Glib::string to std::wstring without changing it in code? Something similar to typedef or #define?

Answer 1

What makes you think that Glib::ustring is interchangeable/interoperable with std::wstring? Most likely if you made that substitution you’d just get a bunch of compiler errors, or if you’re unlucky it would compile and run with different semantics.

I think you’re going to have to bite the bullet and convert your Linux code to use wstring first and then the Windows port should be a lot less complicated.

That said, assuming you don’t need Glib in the Windows version you could remove all references to that and then create your own fake type in a header:

namespace Glib
{
    typedef std::wstring ustring;
}
