Re: [Discuss-gnuradio] gr-osmocom make failing

Many thanks for your help Ron. I did a git checkout of cf954948

That resolved the rtl-sdr compiler error but introduced a blade rf compile error.

I then re-did the cmake with -DENABLE_BLADERF=OFF and

got a clean make and clean make install.

However now at runtime I get the error:

ImportError: libboost_date_time.so.1.54.0: cannot open shared object file: No such file or directory

I have boost 1.58 installed. Is boost 1.54 date_time something different that needs to be in addition to boost 1.58 ?

If so, how would one install just a part of the boost library from a previous version?

It's due to a mismatch between gr-osmosdr and the Ubuntu 16.04 rtlsdr library. There are a few different solutions to this problem.

1) If you're not using RTL-SDR dongles, then just purge the rtlsdr packages (librtlsdr-dev and librtlsdr0). Then rebuild gr-osmosdr and Osmocom RTLSDR should end up in the disabled components during the cmake phase.

2) Checkout a previous version of gr-osmosdr from before this change. git checkout cf954948 should work.

3) The correct solution is to build the rtl-sdr library from source and make sure gr-osmosdr links to that.

gnuradio runs fine.

The old version of Osmocom no longer runs (after some years), so

I started rebuild of gr-osmocom from scratch by cloning from git.osmocom.org/gr-osmosdr

my current appliation is to get rtl-sdr running using Osmocom.

Are there packages I must install to allow gr-osmocom to compile?

Running CMAKE succeeds, with some missing packages:
