Gr-osmosdr compile problems

GNU Radio

Thank you for reading this.

I’ve progressed a little since I last wrote and have received my ezcap
USB dongle. Unfortunately, I’m still having problems.

Cmake produces the following, which seems to indicate that all is well:

– ######################################################
– # gr-osmosdr enabled components
– ######################################################
– * IQ File Source
– * Osmocom RTLSDR
– * RTLSDR TCP Client

– ######################################################
– # gr-osmosdr disabled components
– ######################################################
– * sysmocom OsmoSDR
– * FunCube Dongle
– * Ettus UHD

However, rtl library errors appear during the compiling stage as
follows:

Can someone tell what I’m missing?

I tried to build as well yesterday and failed for me too - as I recall
with the same error. I checked out the code again today and it fails
too but with a different error, so the code is changing at the moment.

You can go back to commit b2128bc86442148d87a7fe897a382c836baf8a67
which compiles fine for me, i.e.

git checkout b2128bc

Is this the correct git syntax?

[root@localhost src (master)]# git checkout b2128bc
git://git.osmocom.org/gr-osmosdr
error: pathspec ‘b2128bc’ did not match any file(s) known to git.

First you make a clone “git clone git:/git.osmocom.org/gr-osmosdr” (I
assumed you already had that), then you change into the gr-osmosdr
directory and do “git checkout b2128bc”

OK Alex, that worked. Now I need to discover why gnuradio compiles with
errors.
