Dear Kerry,
Thank you very much for your message.
I have tested the example in question and found couple typos there.
The shell command on page 396
qmake HelloCint.pro
must be
qmake MyQButton.pro
The ROOT commands there are
root[] gSystem->Load("libHelloCint.so")
root[] MyQButton knopka;
must be
root[] gSystem->Load("libMyQButton.so")
root[] TMyQButton knopka;
I did fix the problems and did test the example works as described with the "standard" ROOT distribution with no "extension"
Please, find the protocol of my Linux session uploaded:
http://root.bnl.gov/QtRoot/expert/19.04.2006/putty.log
All files there were "copy / paste" with the mouse directly from the ROOT Manual and executed "as is".
Please, indicate which version of ROOT you did try.
There were a few bug in the ROOT Qt project files (see $ROOTSYS/include/*.pri)
Thank you very much for your assistance with the ROOT Manual. That typo has to be fixed shortly.
Best Regards

Subject: [ROOT] ROOT Qt Manual Example
Dear ROOT team,
I am using ROOT 5.11.02 on CentOS (linux) compiled with gcc 3.4.4.
I have tried to duplicate the Qt example in the manual. The output of qmake and make are below.
[kerrylee_at_jsc-sf-2148872 MyQButtonEx]$ qmake MyQButton.pro
WARNING: Failure to find: Dict.cxx

make: *** [libMyQButton.so.1.0.0] Error 1
I can omit -lQtGui from the last command and there are no errors, but I cannot load the created library into root. I have also searched for the libQtGui and it does not exist despite Qt being installed correctly.
Any help is appreciated.
Thanks
Kerry
