The UIQ v2.1 SDK for Codewarrior contains an annoying bug that prevents to compile any project imported through its MMP file. Unfortunately, UIQ has decided not to release any SDK update.... Shame on them.

This issue is rather easy to fix however and here is how to get rid of it:
 locate the ide_cw.pm file, located in the c:\Symbian\uiq_21\epoc32\tools directory (if you have installed the SDK in its default location).
 make a backup copy of it
 open it in your favorite text editor
 locate the following line (should be line 471):

        &textSetting($accesspath, "Recursive", "true");

 change the "true" value into "false":

        &textSetting($accesspath, "Recursive", "false");

 save the file

That’s all. You should now be able to import and compile your project without tweaking its settings three time a day.
