Sorry, my bad, I never realized the code in the online tutorial and the offline one are different :-( I actually went through the same tutorial from the tqt3 local documents, found in /usr/share/tqt3/doc/html/tutorial1-01.html This is basically the same page as the online one, but there are small differences in the include files and Qt objects.
#include <ntqapplication.h> #include <ntqpushbutton.h>
int main( int argc, char **argv ) { TQApplication a( argc, argv );
TQPushButton hello( "Hello world!", 0 ); hello.resize( 100, 30 ); a.setMainWidget( &hello ); hello.show(); return a.exec();}
Please try again and let us know. Cheers Michele
Okay. Based on your reply and a response from Gregory Guy, I replaced the include path -I/usr/include/tqt/QT/ with -I/usr/include/tqt/ and got this:
| @10:30:57,leslie@pinto.sixys.site | ~/Documents/SourceCode/QT/Tutorial1 | $ make | g++ -c -O2 -g -m64 -fmessage-length=0 -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables -Wall -W -O2 -DQT_NO_DEBUG -I/usr/share/tqt3/mkspecs/default -I. -I. -I/usr/include -I/usr/include/tqt3 -I/usr/include/tqt/ -o main.o main.cpp | g++ -luuid -o Tutorial1 main.o -L/usr/lib64 -L/usr/lib64 -L/usr/X11R6/lib64 -luuid -ltqt -lXext -lX11 -lm | /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ld: main.o: undefined reference to symbol '_ZN7TQGListD0Ev' | /usr/lib64/libtqt-mt.so.3: error adding symbols: DSO missing from command line | collect2: error: ld returned 1 exit status | Makefile:88: recipe for target 'Tutorial1' failed | make: *** [Tutorial1] Error 1
So apparently I've satisfied the compiler, but not the loader. I see lots of files beginning with 'libtqt' in /usr/lib64, and a subdirectory called /usr/lib64/tqt3/plugins that looks like parts for a QT development tool. Is the fix as simple as adding "DSO" somewhere in the Makefile? Such fun...

DSO should stand for Dynamic Shared Object.
main.o does not seem to link with libtqt-mt.so.3 ( -ltqt-mt )
If your application does not link with, then you should add it in the "LIBS" part of the Makefile.
