[Discuss-gnuradio] Minimal install of GNU Radio without GUI, etc possible?

[Jason McHuff]

Hello, I am building a Linux server running ClearOS (a CentOS 7.2 derivative
https://www.clearos.com/ ) and, among other things, want to use it to decode
and record calls on a P25 trunking system.

I was able to successfully get trunk-recorder working with the GNU Radio
Live DVD (with great audio) and would like to get things permanently working
with Clear OS.  I am wondering if it is possible to do a minimal install of
GNU Radio without any GUI stuff (Clear OS doesn't have a desktop) and just
what trunk-recorder needs to decode P25 using a RTL SDR.

I'm guessing GNU Radio 3.7.5.1-2.el7 which is available in the Clear OS
repos is too old, and when I did try to install using PyBOMBS on it before I
ran into this issue with Apache Thrift
https://lists.gnu.org/archive/html/discuss-gnuradio/2016-06/msg00041.html
and the build-gnuradio script (I think) seemed to mess up the user database,
and overall wouldn't mind doing things manually on a fresh install.
