Error in getting packet trace and statistics( sat-dama-sim-tn9.cc)

[royabhishek353]

1. If I run it without passing the command line arguments:/waf --run "sat-dama-sim-tn9 I get default folder in sim folder where there is no packet trace is available.

2. I am trying to get packet trace and statistics of sat-dama-sim-tn9.cc.I ran it with following command: ./waf --run "sat-dama-sim-tn9 --utsPerBeam=10"

I am getting following error: aborted. msg="ConfigStore tried to read or write an XML file but XML is not supported.", file=../src/config-store/model/config-store.cc, line=107 terminate called without an active exception Command ['/home/raj/bake/source/ns-3.29/build/contrib/satellite/examples/ns3-dev-sat-dama-sim-tn9-debug', '--utsPerBeam=10'] terminated with signal SIGIOT. Run it under a debugger to get more information (./waf --run --command-template="gdb --args %s ").

Hi,

This looks like an XML error... Have you checked that libxml is correcly installed?

[royabhishek353]

I have checked it seems XML is correctly installed xmllint --version xmllint: using libxml version 20904 compiled with: Threads Tree Output Push Reader Patterns Writer SAXv1 FTP HTTP DTDValid HTML Legacy C14N Catalog XPath XPointer XInclude Iconv ICU ISO8859X Unicode Regexps Automata Expr Schemas Schematron Modules Debug Zlib Lzma

After running ./waf --run "sat-dama-http-sim-tn9 --utsPerBeam=2"

I got the following error: Waf: Leaving directory `/home/abhishek/Desktop/ns-allinone-3.29/ns-3.29/build' Build commands will be stored in build/compile_commands.json 'build' finished successfully (1m16.144s) aborted. msg="ConfigStore tried to read or write an XML file but XML is not supported.", file=../src/config-store/model/config-store.cc, line=107 terminate called without an active exception Command ['/home/abhishek/Desktop/ns-allinone-3.29/ns-3.29/build/contrib/satellite/examples/ns3.29-sat-dama-http-sim-tn9-optimized', '--utsPerBeam=2'] terminated with signal SIGIOT. Run it under a debugger to get more information (./waf --run --command-template="gdb --args %s ").

would any one help me out to solve this problem?

Reading your error log : "ConfigStore tried to read or write an XML file but XML is not supported." ns3 needs specific XML packages to read XML files. Please refer to : https://www.nsnam.org/wiki/Installation#Prerequisites

Even if libxml2 (2.9) is installed as suggested by manual.But still I am getting this error.Do any one help me out ?

Can you please print the output of your ./waf configure?

Try to restart the building & simulation, it should work now. If the issue persists, plase open a ticket at https://gitlab.com/nsnam/ns-3-dev as the issue with ConfigStore you encouter is not linked to SNS3 code.
