Hi,
Forgot to mention your comments regarding build:
* I think we add SGSN_Tests.ttcn first explicitly because it is relevant for some reason I forgot. Maybe to generate correct binary file name?
* If you want to build the SGSN, simply run "make sgsn" from the topdir of the git repo and you should be done.
* Have a look at docker-playground.git in git.osmocom.org for already prepared containerized setup to run it (ttcn3-sgsn-tests/jenkins.sh).
