Re: [Discuss-gnuradio] Compiling QT C++ programs with GNU Radio

Maybe I'm just confused, then. You weren't clear about the problem you're experiencing, or what you've tried to resolve it. It sounded in your initial email like you just don't know how to build a CMake project (using "g++", for instance, is not how that works). Further leading me to think this was

Hello Nick, As I have mentioned in my previous email, I know how to use CMake as I have already made a lot of OOTs before. Please understand that I'm not trying to build an OOT. In the program, a top_block_sptr object (think of it as a C++ based flowgraph) object is initialized with signal generato

Hello Nick, Thanks for your email. I have created the OOTs already. What I'm trying to do it to integrate my OOTs in a QT C++ application (something akin to Gqrx). You could see what I'm trying to do from the example source code I attached. Regards, Moses. On Tue, Oct 8, 2019 at 8:56 PM Nick Fost

Hello all, I'm trying to implement an easy-to-use QT-based receiver in GNU Radio. As a starting point, I would like to compile a C++ example (attached) under /gnuradio/gr-qtgui/examples/c++ . This example program generates a noisy sine wave and displays on some qt gui qwidgets. I was able to compil

Hi Ali, I am trying to get an idea of what you really want to accomplish. If it is simply to get text input to your flowgraph, there are several choices, but all of them that I have found buffer a line at a time (ending with return / enter). I have had similar issues. Here are two choices:

Hi, I just tried a very simple example: file source(in ) -> File sink (/dev/stdout ) As long as I feed a few characters to the fifo, nothing happens on the flowgraph side. Finishing the cat command by ctrl-d or ctrl-c leads to attachthread[thread-per-block[0]: ]: fread error But if I write a
