Had a little time to work on the TVRX again.
Have a build of gnuradio installed with pybombs in ~/gnuradio/src/prefix. Very happy to *finally* have a complete source tree and working compile environment to experiment with.
Modified two source files:
~/gnuradio/src/prefix/src/uhd/host/lib/usrp/usrp1/dboard_iface.cpp
~/gnuradio/src/prefix/src/uhd/host/lib/usrp/dboard/db_tvrx.cpp
Went into "~/gnuradio/src/prefix/src/uhd/host/build" and did a make. The files compile cleanly. "make test" works with 100% passing. Then "sudo make install".
The files are installed into
/home/napierm/gnuradio/src/prefix/bin.
uhd_usrp_probe now correctly finds and identifies the rev.1 TVRX board.
Try to run gnuradio and it can't find "liblog4cpp.so.5". And yes, I have run the ~/gnuradio/src/prefix/setup_env.sh first.
Well, this a virtual machine so I revert to a backup from a couple of days ago. Everything works. Change the two files, follow same steps. Broken the same way.
Anyone know the answer?
FWIW, I've attached the two files but since I have no way to test anything I doubt I have the return value right for the Rev. 1 board.
Does anyone have a good methodology to set up a machine with a working UHD/gnuradio build/run environment? I'm pretty frustrated at the amount of time I've wasted on this; there just has to be a better way.
Thanks in advance,
Mark Napier
