Any idea why the compiler might be failing with messages like these? I'm running v0.3.4 (with Gradle) under Wine. It used to work, with v0.3 I think.

looks like some Wine issue, hard to tell from this message

It turns out it was due to the linker not being happy with the interop definitions I had copied from the generated files earlier (to be able to pass numeric constants for a LPWSTR parameter).

What would be the best way to do that now that we have the platforms klibs?

E.g., some win32 functions that take a LPWSTR parameter cleverly allow you to pass either a pointer to a char array (i.e., a string) OR one of several predefined integer constant values; but cinterop treats it as a String parameter, so there is no way to pass the constants.

So I'd like to add an overloaded version that takes a LONG value instead (or ideally, in this particular case, a Short).

Maybe autoconverting from String should be disabled for this funtion in windows.def, in noStringConversion. Have you full list of problematic functions?

[tunedal]

Aha, thanks, I didn't know about noStringConversion.

The affected functions would be the ones that are used in conjunction with MAKEINTRESOURCE, I think. LoadIcon and LoadCursor are the ones I ran into.

However, reading my Petzold (I'm pretty new to win32), it seems you can actually pass the constants as strings! So it's actually fine in this case. 🙂
