Well, if you’re using Ubuntu 16.04 I can send you my working versions of the OsmoTRX and OsmoNITB.
Yes I am using 16.04, thank you
but that is not necessary at the moment.
My project (at the moment) need only basic functionality of osmo-trx…
Need just basic “pilot/beacon” signal kind of real base station emulation to provoke
any cell phone lost in countryside, with no regular network to try to communicate.
That signal I am ready to receive performing TDOA location (multilateration)
from 2 simultaneous positions. All within SAR task (Search and Rescue) in accordance
to ICAO Annex 12 recommendations.
At the moment I am using two sets combined of one limeSDR and one SDRPlay RSP1
with some antennas, LNA and PA in combinations. Tomorrow who knows, XTRX in
stack of 8 maybe 
Project is within my learning curve, non commercial… it is aviation and marine safety voluntary level.

Any ideas?
Ok, cool, good luck on getting your project working!
@zodiac-tiger tnx, I am far from that but still ready to learn 
@skyinlife
Soapy not properly installed…
Reinstall in accordance to @martywittrock instructions
When you have CubicSDR running with Lime than all with soapy is good.

Anyway.
Made a full reinstallation of soapy, rtl-sdr works very well, LimeSDR still does not work.

Some Alerts, some Errors, but it seems ok… or not
@Zack any recent firmware/gateware updates that could have broken support for applications such as OsmoTRX?
Hey, thanks for this. I created a fresh install of Ubuntu 16.04 in VMWare fusion and now OsmoTRX is communicating with OsmoNITB. Unfortunately, I’m also getting the errors reported below, but I’m on the right track now.
EDIT: Actually, despite the errors and warnings it appears to be working! Great!!
Second to that, on my side.
Cell phone can see my local G2 network,
connect
and
with *#100# able to get the number.
Later, sqliteDB checked, IMEI of my cell recorded ok

@andrewback @9a4db would you please share step by step installation guide of osmoTRX+osmoBTS on Raspberry PI, i am newbie and required help, i just watched https://www.crowdsupply.com/lime-micro/limesdr-mini/updates/gsm-base-station-demo,
Please use above set posted by IgnasJ
That one reporting some errors and warnings but working.
On my side I am able to connect on network,
request the cell number by typing *#100#
than SMS between each other, call goes too but sometimes
have timeout on them. Max number of 2 cell phones tested.
@IgnasJ thanks i’ll try this.
please help
Please do not post lengthy output such as this direct to the forum and instead use something like Pastebin and share a link to it.
Note that I didn’t use any of those configure flags you selected and in particular I’m not sure if –with-neon works on a Raspberry Pi. Try configure without any options, as per the script Ignas shared.
@andrewback i tried without options as per install.sh script but the same compiler loop.
Not sure what to suggest, other than trying to work out what the problem is by searching to see if others have encountered this. Failing which posting to the Osmocom mailing list.

I was able to successfully fire up a GSM900 (arfcn 975) with osmo-nitb, osmo-btx-trx, and osmo-trx. The downlink at 925.2 Mhz is visible in GQRX with RTL dongle. Looks great and terminal log messages appear to be clean. Cell phones discover it as “Test PLMN 1-1”.
Then I try to attach a cell phone to it ( I run it with “auth policy accept-all” ) and none of the phones I tried can connect to the network. I can see uplink bursts from cell phones on GQRX around 880.2Mhz, but no activity in terminals and then a message on the cell comes up “Cannot register with the network at this time…”. Does anyone know how to debug this issue? Do I need to run something else in addition to osmo-nitb, osmo-btx-trx, and osmo-trx to allow registration? thanks.
