Re: Problem using wx headers in XCode

OK, thanks.

I’ve now included a recursive path that *should* find setup.h, but still no joy.

I’ve just found an article that describes similar issues, though some time ago, that suggests that I define a custom build parameter, USE_HEADERMAP, with a value of NO, so now I have to try and figure out where I can set this without having to tackle the Xcode UI (sigh).

Thanks for the assist.

Adding this path reports no errors relating to wx.h, so I’m assuming that the file is now being found. However, the build fails with too many errors relating to WX types and methods not being defined, so I’m assuming that other headers are still not being found. Making these changes in the Base.xcconfig and getting differing results gives me confidence that I’m editing the correct settings file.
