Hi, I'm trying to learn to write a GUI app using the book "C++ GUI Programming with Qt 3", which of course is not written with Trinity in mind, but hopefully will be enough to get me started. I've already figured out that I need to substitute 'tqmake' for 'qmake', but I can't get the simple 'helloworld' project to actually compile the c++ code. I've got the project generated, and I see the code in its src/ directory, but when I try to build it (the book says to use 'make') it says "make: Nothing to be done for 'first'."
Take a look at the QT3 tutorial here https://www.trinitydesktop.org/docs/qt3/tutorial.html Should be able to get you started with TQt ;-) Cheers Michele
Okay, I tried that and got exactly the same results. The tutorial you cited even has the same mistaken instruction to use qmake instead of tqmake.

I tried tutorial 1: copied the code to a .cpp file, followed the exact instructions (except replacing qmake with tqmake as you already pointed out). Works perfectly on my system. This is a pretty basic tutorial ofcourse, no TDE stuff there, no tqtinterface. Try to give it a second try :-) Cheers Michele
Okay, I removed all files from my Tutorial1 directory, and started over. Here's what I get:

So, different, but still not working. I searched for qapplication.h and found it in /usr/include/tqt/QT/, but adding -I/usr/include/tqt/QT/ to the Makefile INCPATH made no difference.
