I've recently been trying to install the Gnu Radio system on a new machine using the build-gnuradio script.
I guess you are referring to the script `build-gnuradio`[1] recommended by the gnuradio wiki[2]. This script fetches the master of gr-osmosdr from the upstream osmocom git repo but the master of rtl-sdr form a fork by patchvonbraun[3].
The script is failing with an error in the gr-osmo[sdr] build phase, and I've been able to verify this with a separate attempt to build.
gr-osmosdr depends on rtl-sdr and since commit 3c7d3f16 gr-osmosdr requires patches in rtl-sdr which introduced bias-tee support (for respective hardware). Those patches are applied in the latest master in the upstream git repo of rtl-sdr, but not in the fork by patchvonbraun. Thus the build fails.
I recommend to modify the build-gnuradio script in a way to use the upstream repository of rtl-sdr[4], or to pull the latest changes from upstream into the fork by patchvonbraun.
Sincerely, Fabian P. Schmidt / kerel
