Forgot to include the mailing list... ---------- Forwarded message ---------- From: Felix W. <wunsch.fe...@googlemail.com> Date: 2014-03-31 10:20 GMT+02:00 Subject: Re: [Discuss-gnuradio] gr-drm for GNU Radio 3.7 available To: Jordan Johnson <jwllmjohn...@gmail.com>
About the "no module named drm" error: Obviously the needed library is not found. Normally, a "sudo ldconfig" should solve this, but only if it can find it. So your library has to be placed somewhere in the standard paths like "usr/local/lib", where also the other GNU Radio libraries are located. Looking at the man page of "ldconfig" it seems that you can also give it a path to your shared library. Maybe that's already enough. Because you couldn't execute the hierarchical blocks the respective files were not generated and this is why they are missing when you open the transmitter flow graph. GRC is just telling you that the MLC blocks are missing and therefore it can't connect them to the adjacent blocks. To sum it up: Try to find out where the working GNU Radio files such as XML files and shared libraries are placed and install the DRM stuff there. Unfortunately, I'm not familiar with the differences between Arch and Ubuntu so I'm sorry that I can't give you more detailed instructions. Keep me posted about your progress! 2014-03-31 9:56 GMT+02:00 Jordan Johnson <jwllmjohn...@gmail.com>: Shoulda figured. Arch likes to put things in /usr/local/share as opposed to > /usr/local.
