[Kde-bindings] Re: Notes on building on Mac OS X

[Adam Higuera]

If there's still interest, in order to get Smoke to work right with the
frameworks, I put the following into the file "generatorpreprocessor.cpp".
 It's an ugly kludge, but it might save you some irritation.

    // skip limits.h - rpp::pp gets stuck in a endless loop, probably
because of
    // #include_next <limits.h> in the file and no proper header guard.
    if ((fileName == "limits.h" || fileName == "stdarg.h") && type ==
rpp::Preprocessor::IncludeGlobal)
        return 0;

QRegExp rx("(Qt\\w+)/([\\w\\.]+)");
if(rx.indexIn(fileName) != -1) {
  fileName = "/Library/Frameworks/" + rx.cap(1)
+ ".framework/Headers/" + rx.cap(2);
}
