[tde-users] Re: [users] TQt Tutorials

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?
