Hi all, I am new to all of this, so I’m looking for some guidance. I recently setup UHD and GNURadio using PyBOMBS on Ubuntu 14.04. I now want to do a git pull and update my stuff. I’m not sure what commands to execute after I do the git pull for each. For example, I found two different recommendations for updating gnuradio after a git pull First way: _git pull_ _rm -Rf build_ _mkdir build_ _cd build_ _cmake …/_ _make_ _sudo make install_ Second way: _git pull_ _cd build_ _make_ _sudo make install_ Is the removal of the existing build directory and cmake command necessary? After executing git pull, what directory do I need to go to and commands do I need to run for PyBOMBS and UHD? v/r, Rich ---

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: ./pybombs update …although I don’t think this will update pybombs itself. M ---

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 was in gnuradio. From the pybombs/src/uhd directory where do I need to be to execute make and sudo make install? 3. There is also no build directory in pybombs, where should I execute make and sudo make install?

Hm, I thought that’s what it would do. Maybe it just git pulls. > 1. There is no build directory in uhd, like there was in gnuradio.

It’s pure Python, and doesn’t get installed, so it just needs a build process. M ---

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 below to explanation of ./pybombs update. [http://gnuradio.org/redmine/projects/pybombs/wiki/Using](http://gnuradio.org/redmine/projects/pybombs/wiki/Using) Unfortunately, the wiki also recommends that we don’t update each recipe manually, because we could break a dependency. So at this point, I’m still not sure what I’m supposed to do to update my install when new versions of gnuradio or uhd come out. Can someone with experience in this flow chime in for me. Much appreciated. Rich On Wed, Oct 29, 2014 at 2:46 PM, Martin B. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Just reinstall it. No hassle 🙂 M ---

I’m still asking for help with this maintenance process. I tried the ‘./pybombs remove’ command to get rid of uhd and gnuradio as a test. I didn’t get any error or warnings and it completed. When I looked in the pybombs/src folder, both gnuradio and uhd folders still existed there. I deleted them by hand. I then tried the ‘./pybombs install uhd’ command to reinstall uhd, but pybombs seems to think it’s installed. I’m really at a loss as to how I’m supposed to do things here. I think in theory, pybombs would make all of this painless, but I’ve either done something terribly wrong and screwed pybombs up at this point, or it’s not working as intended. What should I do at this point to fresh install with pybombs? I checked the packages I have installed on my ubuntu and I don’t see gnuradio or uhd in the list, which is good. If I deleted the pybombs folder and start over from there, would you expect a clean installation at that point? Is that what Martin meant by “Just reinstall it”?

Try running Pybombs clean gnuradio Pybombs clean uhd And then installing -Tim
