TTCN-3 Execution Error [message #1785522]

Hi All

I am trying to execute 3GPP IRAT test cases.

My compilation and build for LTE_IRAT_Testsuite is successful. I get unexpected error "ttcn3_start: error: Something went wrong..." while executing test case from the suit.

I have titan core 5.5.0
Following is last portion of log where error happens

"Initializing module IMS_Procedures_Common.
Initializing module IMS_IP_Config.
Initialization of module IMS_IP_Config finished.
Initialization of module IMS_Procedures_Common finished.

my .cfg configuration as follows

Hi peeyush,
based on the little information you provide it's impossible to tell what could be the problem.

Please try to start your executable not with the start script ttcn3_start, but step by step , as described in
https://www.eclipse.org/forums/index.php/t/1068004/

I general I'd recommend you start with something simple and get familiar with the tool first.

Best regards
Elemer

Hi Elemer

I will try step by step procedure once, thanks for advice.

Hi Elemer

I tried step procedure.

On Main Controller Terminal I got Following Log

Using configuration file: SSNITZ_Testsuite_2.cfg
MC@svp3glinux-Samsung-DeskTop-System: Unix server socket created successfully.
MC@svp3glinux-Samsung-DeskTop-System: Listening on IP address 127.0.0.1 and TCP port 10752.
MC2> cmtc
Waiting for HC to connect...
Error: HC connection from localhost [127.0.0.1] was refused because of incorrect version.

And on other Terminal I got following log

:~/TTCN3/LTE_IRAT_IWD_16wk49$ ./LTE_IRAT_Testsuite 127.0.0.1 10752
TTCN-3 Host Controller (parallel mode), version CRL 113 200/5 R5A
The address of MC was set to a local IP address. This may cause incorrect behavior if a HC from a remote host also connects to MC.

Please the above command line output and suggest.

Thanks for all help

Hi Peeyush,

OK that makes it clearer: the binary execution ends up in a segmentation fault. The reasons can be manifold: compiler fault, external C++ code, configuration issues.

Please upload your code, including Makefile and configuration file and we will take a look.

Best regards
Elemer
