Can you please run the nas_test manually and provide the console output?

alvasMan commented 4 years ago

There is an concurrency issue in the NAS test where you might try to stop the stack thread before you are finished starting it. That might be causing your issues.

Could you try the following:

diff --git a/srsue/test/upper/nas_test.cc b/srsue/test/upper/nas_test.cc

How to manually run the nas_test command?

In your build folder, run ./srsue/test/upper/nas_test

There is an concurrency issue in the NAS test where you might try to stop the stack thread before you are finished starting it. That might be causing your issues.

Could you try the following:

Can you elaborate, how will I execute my command.

What does it mean about the" apply the fix".

OK, I'm not sure if you applied the fix or not, so I'll just explain it very thoroughly, just in case you didn't understand.

1 - Open srsue/test/upper/nas_test.cc in you favorite text editor. 2 - Add the line that I told you previously, namely usleep(5000);, just after the stack.init(&nas) line. 3 - Re-compile srsLTE (make && sudo make install && sudo ldconfig) 4 - Run the tests again ctest -j8

If the tests are still failing, please send an e-mail to the mailing list and we will continue the discussion there.
