I am working on a network management application with Qt and I chose to use Wt for UI, because with it I will not have to deal with any of web parts (PHP, AJAX, HTML\/CSS) and it’ll be usable on all platforms.<\/p>\n

I successfully managed to compile and run examples using cmake. Although I am used to QtCreator IDE and qmake I would rather use that for development and compiling.<\/p>\n

I got stuck trying to compile “wtwithqt” example in QtCreator(qmake).<\/strong> I’ve been searching everywhere for some guide how to compile it with qmake. However I found nothing helpful.<\/p>\n

Here is my .pro file.<\/p>\n

    Your makefile is pretty much sound, but I think you’ve forgotten to link the wtwitqt<\/code> interop layer. Add -lwtwithqt<\/code> to the LIBS<\/code> line,<\/p>\n<\/li>\n<\/ol>\n
