This I don't understand; you'll have to ask on the list what's happening there.

Note however that there's an error in the project's CMake files (references to non-existing files) and seems to be hardwired for MSWin, so this exercise won't help you very much.
It also doesn't help with the "Did you mean std::Foo" class error. 

BTW, I don't think that one happens because KDevelop does not see the class definitions, because it will happily take you to the std::Foo definition (e.g. std::AboutDialog is defined in AboutDialog.h, according to KDevelop).

I'm also seeing errors about std::wxString being an imcomplete type.

To me this suggests that somehow the KDevelop parser adds a "using std" or similar that makes the std the active namespace. Go figure out where that happens ...

What also is bound NOT to help is the fact that the project uses an explicit include header that is included via a compiler argument (`-include AudacityHeaders.h`). I think that this is not well supported by KDevelop.
 
---
I add 2 explicit header search paths to the standard Makefile-based project: the wxWidgets include directory (/opt/local/libexec/wxWidgets/3.1/include/wx-3.1 for me), and the corresponding gtk2-unicode directory (/opt/local/libexec/wxWidgets/3.1/lib/wx/include/gtk2-unicode-3.1). I also add 3 custom defines: WXUSINGDLL=1, _FILE_OFFSET_BITS=64 and __WXGTK__=1 .

With that, I get no parsing errors, and I cannot reproduce your crash on PlayableTrackControls.cpp either.
