[Discuss-gnuradio] 回复： How to compile the example alone？

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!

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: https://gist.github.com/haakov/7561494f3eaf77d4259d5abea33c0c4e

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!
