Dear Gnuradio members, I am working on a port for GR-AIS to version 3.7. The initial version was for GN3.3, later it is merged to CMake.
The problem is that I am trying to compile Gnuradio with the gr-ais extension on a beaglebone black (bbb). I managed to compile 3.7 on the bbb, but the problem is that I don't have GRUEL available. On a x86 it is possible to pull (libgruel) from the package-manager. So I decided that the fastest to get everything running is to upgrade gr-ais to version 3.7. I managed to do this using the wiki<http://gnuradio.org/redmine/projects/gnuradio/wiki/Move_3-6_to_3-7> . I believe that the cpp is up and running, it compiles fine, but am running into some problems with CMake. I haven't worked with CMake before, so I haven't worked with the scripting earlier. The problem is CMake+SWIG. When Python tries to invoke Boost it gives an error. Traceback (most recent call last): File "/usr/local/bin/ais_rx.py", line 15, in <module> from gr_ais import * File "/usr/local/lib/python2.7/dist-packages/gr_ais/__init__.py", line 45, in <module> from gr_ais_swig import * File "/usr/local/lib/python2.7/dist-packages/gr_ais/gr_ais_swig.py", line 26, in <module> _gr_ais_swig = swig_import_helper() File "/usr/local/lib/python2.7/dist-packages/gr_ais/gr_ais_swig.py", line 22, in swig_import_helper _mod = imp.load_module('_gr_ais_swig', fp, pathname, description) ImportError: /usr/local/lib/python2.7/dist-packages/gr_ais/_gr_ais_swig.so: undefined symbol: _ZN5boost6system15system_categoryEv I have re-installed Ubuntu 13.10 and installed gnuradio with the latest git version. The make test succeeded. I have forked the gr-ais repository into a seperate public repo <https://github.com/Fokko/gr-ais>. If someone has any idea, please let me know! Kind regards, ing. Fokko Driesprong
