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

Leslie 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

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.
