I'm trying to get a handle on writing an app for Trinity, starting with stuff
from the Wiki; but it's a struggle.
	I Followed
		Support =>
			Wiki =>
				Developers =>
					Tutorials and Documentation for QT and TQT
and hiding under the QT3 API Documentation link (which really points to
						TQt Reference Documentation (Open Source Edition)
I found the Getting Started section.  Following How To Learn TQt showed me C++
GUI Programming with TQt 3 (which I have ordered); many of the other links on
this page point to a now-deceased TrollTech website. :-(
	I moved on to Tutorial #1, and after figuring out that references to "qmake"
should really be to "tqmake", I tried compiling the fourteen example
programs.
	They all fail with the same error. Example #1 is typical:

|	$ make
|
g++ -c -O2 -g -m64 -fmessage-length=0 -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables -pipe -fvisibility=hidden -fvisibility-inlines-hidden -Wall -W -O2  -DQT_NO_DEBUG -I/usr/share/tqt3/mkspecs/default -I. -I. -I/usr/include -I/usr/include/tqt3 -o
main.o main.cpp
|	g++ -luuid -o hello
main.o    -L/usr/lib64 -L/usr/lib64 -L/usr/X11R6/lib64 -luuid -ltqt -lXext -lX11 -lm
|	/usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld:
main.o: undefined reference to
symbol '_ZN13TQApplication13setMainWidgetEP8TQWidget'
|	/usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: /usr/lib64/libtqt-mt.so.3:
error adding symbols: DSO missing from command line
|	collect2: error: ld returned 1 exit status
|	make: *** [Makefile:88: hello] Error 1

in which the loader seems to be complaining about setMainWidget, a method of
TQApplication.  It seems to be expecting to find it in
|	/usr/lib64/libtqt-mt.so.3
and I see on the web that adding
|	-ltqt-mt
will fix the problem, and several web responses say to use
|	./configure LIBS=-ltqt-mt
but how would I do that with tqmake?
