RT-Tester 6.0-6.4.0 now available (new feature)

A maintenance release is now available for all supported platforms.
Consider updating if you are using Version 6.0-6.3.1 or older.

New Features

  1. Allow Signal Logging to Socket (implements #15208):
    • If configuration field SIGNAL_SOCKET (e.g. in project.rtp) is given, then
      this determines a UDP output port for signals/events in a simple line-based format;
      this output can be evaluated by arbitrary tools (including the simple rttsockcat)
    • Added a matching matplotlib-based python utility rtt-live-sigplot.py
      that continuously plots values received on a UDP socket graphically
      Note: recommended Python-2.7, matplotlib has to be installed
  2. RTTL timer feature (implements #6143):
    • new RTTL commands @startTimer, @elapsed, @timerValue
    • documentation in manual (including EBNF)
    • utility rtt-inspect-test now accepts option ‘--timers‘ to display the used timers
  3. Testbed Version identification (project.rtp):
    • allow new fields TESTBED_VERSION or alternatively TESTBED_VERSION_FILE
      (implements #15017)
    • this can be inspected by rtt-swi-info --testbed-info
    • Documentation rtt-doc-test includes this information in file astsversion.tex.


  1. Utility rttsockat:
    • New option --remote / -r, allows to listen to datagrams from
      remote machines
  2. License Management:
    • added deployment of minimal license server provision (RTT-LIC-SERVER.tgz)
    • in rt-tester-license-mgmt.pdf, explain how to set up a license server
      for Windows and Linux machines (implements #15228)
  3. RTTL code expansion (rtt_prep_rts):
    • for @rttGetPtr, use standard GNUC macro __typeof__, if appropriate
      (implements #15219)
  4. Enum pre-processing (rtt_prep_enum):
    • robustness: allow syntax typedef enum : <type> { ... }
      Note: objective C extension, used e.g., in /usr/include/sys/qos.h
  5. DEMO suite (rtt-create-project -u DEMO):
    • Included version V-1.2 supports live plotting of signals
    • Example for RTTL timers has been added (swi-tests/test-20)
    • Example use of new field TESTBED_VERSION_FILE


  1. Pre-Processing of character literals (rtt_prep_rts):
    • RTS pre-processing now treats '"' as alternative to '\"' as character literal, as many compilers do (implements #15196)
      Note: '"' is expanded to K&R standard '\"', so the compiler does not need to accept it.
