I use gentoo at home and have no difficulty keeping gnuradio up to date. At work we’re on a standalone network (no internet) so occasionally bring computers home to update them. Lately, I’ve been having trouble with pybombs. Using a freshly installed ubuntu 15.04, then doing an apt-get update apt-get upgrade [not sure the update was necessary] I first used apt-get install gnuradio Thinking better of it, I ran apt-get remove gnuradio apt-get autoremove Then went with pybombs git clone git://github.com/pybombs/pybombs cd pybombs ./pybombs config [use install path /usr/local/gnuradio] ./pybombs install gnuradio And after several tries continue to receive this error: […many lines of install…] Unpacking liblog4cpp5-dev (1.0-4) … Setting up liblog4cpp5-dev (1.0-4) … installation ok via: deb Installing from source: gnuradio Cloning into ‘gnuradio’… Checking connectivity… done.

Mike, When I ran into this problem, I had to reinstall pybombs. I think the problem lies in changing the installation prefix after installing pybombs. I’m sure there is another way to fix this, I just don’t know what it is. When I reinstalled pybombs, I defined the installation prefix when the several prompts are asked at the beginning.

Thanks, Nathan, and all who replied publicly and privately, The problem seems to be that I had installed Anaconda (from Continuum Analytics) which does not include Cheetah by default. It does exist, however, in the python tree installed by ubuntu, and that seemed to confuse things. I installed Cheetah within the anaconda tree and I believe all is well. I can say for sure when compiling completes!

Logan, For your case deleting inventory.dat would do the trick of effectively resetting pybombs state (and if your done with an install rm the prefix) Mike, Pybombs is hiding the true error. Cmake failed for either VOLK or GNU Radio. Try running pybombs again with -v -v ---

Thanks Nathan. Should I have to use sudo when using pybomb commands, now that the installation prefix is outside of my home directory(because I now I have to use sudo when using pybomb commands)?

You only have to use sudo with pybombs if you don’t have write permission to your prefix. In general it’s best to avoid using sudo and pybombs together if possible (with the exception of when pybombs asks you for sudo password when using apt-get install). You can either set the prefix to somewhere your user normally has write access to (typically your home directory), or alter permissions of your prefix. As an example, if you were setting your prefix to /opt/gnuradio/pybombs-v3.7.8 the least obtrusive way to do this is sudo mkdir -p /opt/gnuradio/pybombs-v3.7.8 # assuming your user doesn’t have write access to /opt/gnuradio you need sudo to mkdir sudo chown myusername:mygroupname /opt/gnuradio/pybombs-v3.7.8 ./pybombs install gnuradio In practice I usually make a group on my machines called ‘developer’ and add my user to it, then give the developer group ownership or write access (depends on what I feel like when I set up a new machine) to /opt. That lets me write whatever to /opt without sudo (don’t forget you need to login after adding your user to group for it to take effect). The same principle can be used with /usr/local or any other directory, but IMHO you should at least make your work an extra layer deep so you can just rm -rf the whole prefix (without root!) and not have much to worry about damaging.

So I changed the install prefix to /home/username/thesis/target and then deleted the inventory.dat file and removed the previous install prefix folder(this was usr/local, but it actually ended up in usr/local/share, I’m thinking this was a problem because I think there are lingering files). I’m having problems now, I can’t remove or update any packages, it states that there is not an inventory file so it creates an empty one and then states there is nothing to do. Is there a way to have it generate a new inventory file? I can’t install any packages because they seem to still be in the pybombs folder. Do you have any advice Nathan? My initial reasoning for changing the install prefix to usr/local/ was to enable me to create my own OOT modules and build the tutorial examples. When pybomb’s install prefix was in my home directory it kept throwing an error about the CMake files. I tried to change the install prefix locations within those CMake files but that didn’t seem to fix my problems. I’m really starting to learn that a little knowledge can be a pretty dangerous thing haha.

Hi Logan, Here is a full set of commands for installing in your own home directory via pybombs: git clone [GitHub - gnuradio/pybombs: PyBOMBS (Python Build Overlay Managed Bundle System) is the GNU Radio install management system for resolving dependencies and pulling in out-of-tree projects.](https://github.com/gnuradio/pybombs) cd pybombs ./pybombs config sudo rm -rf /home/gnuradio sudo mkdir /home/gnuradio sudo chown -R linux /home/gnuradio /home/linux/pybombs rm -rf inventory.dat src linux@Linux:~/pybombs$ ./pybombs install -v -v gnuradio add gnuradio and all apps you want, then change path to: source /home/gnuradio/setup\_env.sh linux@Linux:~$ sudo gedit .bashrc linux@Linux:~$ source ~/.bashrc Good luck! 🙂 BR, Iluta On Tue, Aug 4, 2015 at 5:25 PM, Washbourne, Logan \< ---

Thanks Iluta and Nathan, My problem was not being able to use the gr-tutorials examples if I didn’t have Gnuradio installed in /usr/local, but then I realized that the gr-tutorials was also a pybombs recipe so I used pybombs to install it and everything worked out great! Thank you both for helping me learn how to move my install prefix around and about proper folder locations. Logan Washbourne Electrical Engineering Graduate Student (Electromagnetics)
