Thank you very much! I have read your code. It's helpful.
Actually, the problem I met is in here
https://lists.gnu.org/archive/html/discuss-gnuradio/2018-03/msg00004.html
when I use qt5's library to compile, it will exit code 139 (interrupt by signal
11: SIGSEGV). The error is showed in the last picture of that question. And I
also try to compile it by qt4 and it's normal except for some messy code.
I am very curious about why you not met the question when you compile program
by qt5 libraries.
Thanks again!

主题: Re: [Discuss-gnuradio] How to compile the example alone？
Hello ruiy!
The display_qt example is compiled when you compile GNU Radio with gr-qtgui. So
the executable should have the following path:
gnuradio/build/gr-qtgui/examples/c++/display_qt
If you want to rewrite CMakeLists.txt to compile it alone, I believe I can help
with that. :) I'm not an expert in CMake, but I can point you to a
CMakeLists.txt that I've used for the same purpose.
I have uploaded it at:

Hope this helps!
Best regards

I discover a example about how to compile the qtgui in c++. The example's path
is "gnuradio/gr-qtgui/examples/c++/display_qt.cc"(The website is
https://github.com/gnuradio/gnuradio/tree/master/gr-qtgui/examples/c%2B%2B).
But I don't know how to compile it singlely. I try to rewrite the
CMakeLists.txt. However, I fail...So if anyone know how to compile the
display_qt.cc or how to rewrite the CMakeLists.txt, please teach me. Thanks
very much!
