[Discuss-gnuradio] problems with redmine

I can't seem to make an account (it says my email is already registered and when I try to recover a lost password I get no such users). The issue is that python-zmq needs to be installed for the test t

Well, I can tell you that I deleted the gnuradio build directory and then executed ./pybombs update to see if it would start the build process. It did not. As of now I'm not really sure what ./pybombs update does. The wiki leads me to believe it's supposed to do the pull and build process, link bel

Thanks Martin, I dug out the S&C paper and think I'm clear on that, thanks. I have a currently uncoded system with superimposed QPSKs from multiple sources so it's pretty sensitive! its fine using the Octoclock, though giving 0 BER end-to-end. I also have 32 symbol packets; so fairly long. I've

Thanks Martin, but I'm still unsure of this process. 1) I tried using ./pybombs update, but it doesn't look like it initiated a build process on anything. Did you mean to imply it would do that, or just the git pull process for gnuradio and uhd? 2) There is no build directory in uhd, like there w

2014-10-29 Thread Martin Braun
Sometimes it's safer to clear the build dir, usually it's OK to leave in. If you have any cmake variables set, you'll need to reset them if you clear the dir. UHD is updated the same way. In all cases, it depends where you installed your stuff. pybombs can do all this for you, by the way: ./pybom

"Right" is whatever makes your life easy. You could only ever install out-of-tree modules into ~/.gnuradio. You could only ever use modules available in binary packages... Why not try pybombs instead? If you're careful about how you set up your sources, you can probably install everything from bina
