libusrp-3.4.2.so.0: cannot open shared object file: No such file or directory

The problem is that you system cannot find the needed library (libusrp-3.4.2.so.0 in this case). The way to remedy this is by adding the file location (/usr/local/lib for gnuradio) to the /etc/ld.so.conf file, as shown [ here]. Follow this by updating the ldcache: 

sudo ldconfig

virtual bool usrp_standard_tx::set_tx_freq(int, double): Assertion `dac_rate () == 128000000' failed.

This means you have the wrong version of gnuradio installed. Make sure you get a version > 3.3

bind() failed: Address already in use

This means there is a stray transceiver process. You'll need to kill it to free up the needed port. 

[dburgess@localhost apps]$ ps
  PID TTY          TIME CMD
23233 pts/1    00:00:00 bash
23342 pts/1    00:00:32 transceiver

USRPDevice.cpp:353: WARNING -- UNDERRUN in TRX->USRP interface

Problem: The software is not feeding transmitted data to the radio fast enough to keep up with real time. An occasion underrun is OK, but more than a few every few minutes will make your system unusable.

Solution(s):

  • Try running the transceiver and OpenBTS under nice to improve priority.
  • Kill other applications to free up CPU resources and reduce swapping.
  • Get a faster computer. A 1.6 GHz single-core Intel should be adequate, though.

Transceiver.cpp:519: RX failed to tune

TRXManager.cpp:357: RXTUNE failed with status 1

TRXManager.cpp:409: POWERON failed with status 1

TRXManager.cpp:422: SETPOWER failed with status 1

Problem: You may be running the wrong transceiver program for your USRP hardware. For a Range Networks radio, use TransceiverRAD1. For Ettus boxes (w/ 52mhz clock), use Transceiver52M. We no longer support 64 mhz (the default USRP1) clocks.

CENTOS Install Problem

Problem:

When building the subscriber registry on Centos 5.5 you get the error message: 

openbts/trunk/sqlite3/sqlite3util.cpp:20: undefined reference to `sqlite3_prepare_v2'
collect2: ld returned 1 exit status
make: *** [srmanager.cgi] Error 1

Workaround: The Centos version of libsqlite3.so.0.8.6 does not contain 'sqlite3_prepare_v2'. A work around is simply to use sqlite3_prepare instead. Change all function calls and the problem should go away. Currently it is only being called in openbts/trunk/sqlite3/sqlite3util.cpp.

OpenBTS exits without any output or error

Problem

After building OpenBTS application and running the main app/OpenBTS application as root the application exits without any output or error message.

Solution

A Likely cause is that the configuration files and directories have not been created or are not accessible. Try to create the /etc/OpenBTS directory with 777 permissions. And make sure you have the initialized OpenBTS.db configuration database in /etc/OpenBTS .
