There has been an issue for some months now in the latest build of gnuradio from the AUR. It does not build, nor can run the WX/QT GUI modules. I have had to downgrade some packages to make an older version of GNR work. I need the instrumentation tools for testing things and cannot work without them in some applications. Has anyone come up with a parch or workaround? ---

Hi Jordan, Can you be more specific in the versions and problems you’re talking about? Downgraded from what to what? When you can’t build, what kinds of errors are you running into? What’s the problems that you wee with WX/QT GUI? Tom ---

Everyone is claiming different versions: 3.7.2, 3.7.2.1, 3.7.2.1-1, 3.7.2.1-2. And there’s no indication of what the error is when building. Just that wxgui is not found. No output from cmake that might explain why it’s not being found. The changes between 3.7.2 and 3.7.2.1 were not that profound. Only a few cmake fixes that shouldn’t affect this, and no changes to wxgui. In your followup email, you show some errors when trying to run a wxgui application, but I thought wxgui wasn’t getting installed? How could it possible run at that point? Please, please try and be clear and complete when explaining how things are going wrong. Tom
