Hello, could you please help me solve this issue? I was trying to run the kiwisdr in gnuradio and encountered this error below. Not sure what to do. Thank you!

Hi @williamntv

the relevant error message is

AttributeError: 'module' object has no attribute 'kiwisdr'

and it means that the kiwisdr block is not available in python, i.e., it has not been build.

Have you installed doxygen? If not please install it, sudo apt install doxygen, and then run cmake and make again in a clean build directory.

Also make sure you have swig3.0 installed (sudo apt install swig3.0).

Thank you for your reply. Me and my lab partner, we managed to re-install all the required software packages and the block is now showing in gnuradio. However, we are now facing yet another issue. As soon as we tried to run script, it would crash to desktop right away. My lab partner found that the issue is with segmentation fault and we don't know what else to try. Maybe we will have to reinstall gnuradio and see if that will help. We are working on Seismograph project for a radio course at University of Victoria, by the way. Thank you for your support.

Have you run volk_profile ?

Can you start your flowgraph in the debugger and make a backtrace? i.e. generate top_block.py and then run gdb python and then in gdb run top_block.py. When it crashes you can then get a backtrace using bt.

Do you have any news on this issue?

williamntv commented 4 years ago

Hello Chris, thank you for reaching out to me. Unfortunately, we were short on time and weren't able to completely resolve the issue. We tried to clean and re-install GNURadio but to no avail. The program kept crashing on us whenever we tried to run it. Yes, my partner did try to debug it and the same message came up saying "segmentation fault". We had to give up and focus on the final exam. Very unfortunate because we came so close to getting it working. We felt that we were not very well equipped with knowledge in Python and programming so we just couldn't pull it off. Anyway, once again, thank you for your support.

Hello, I also had this issue. I compiled the maint-3.7 branch on ubuntu 18.04 and the packaged version of gnuradio (3.7.11-10). After reading this i installed swig3.0 and doxygen and completed a clean build again and the reported error went away :)

PS: I however received a different error, and I have logged #5 for that.

Good to hear that it was helpful.
