Hello to everyone involved with this worthwhile project.
As an I.T. professional and amateur radio operator who does a fair amount of satellite telemetry reception, I thought it would be interesting to purchase the patch antenna / LNA / SDR “DIY” kit to see if I could receive an L-Band signal.
Wanting to use existing computer resources, I found the “outernet-linux-lband” project on github and installed the various components.
Even though my location is not ideal (tree cover), I was pleased to get a signal lock with the “sudo demod-presets americas” command.
Unfortunately, when I run the “sudo decoder” command, the following error appears:
ondd: relocation error: ondd: symbol ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEC1EPKcRKS3, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference
Please note that the “alias decoder=‘sudo /usr/local/bin/decoder -o /srv/downloads -c /var/spool/ondd’” has been added to .bashrc.
… I have searched online but have not found a solution that made any difference. Not being a programmer, the exact meaning of this error is beyond my scope, but I am very experienced at locating solutions to issues such as this. However, I am not having any luck this time.
My system is Ubuntu 64-bit v14.04.01 with the following output from “uname -a”:
Linux k4kdr-linux 4.4.0-34-generic #53~14.04.1-Ubuntu SMP Wed Jul 27 16:56:40 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
My compiler-related app versions are:
gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4
GNU Make 3.81
install (GNU coreutils) 8.21
… I do believe that the use of existing computers for Outernet would increase the number of people participating and discussing the project which of course is a good thing. If the decoder app will not run on my particular OS, that’s fine but I did not want to give up without asking here.
Thanks and best of luck with the project.
