1 crashed and 3 skipped tests in my tests of ./test.py

[zhouy...@gmail.com]

Hi, I install ns-3.18 in the ubuntu 14.04, and I have worked step by step as tutorial says to install and test the ns-3. But when I test my ns-3 using ./test.py, it turned out to be wrong as follows: 

......

PASS: TestSuite ns3-tcp-state

SKIP: TestSuite nsc-tcp-loss

PASS: TestSuite ns3-tcp-loss

PASS: TestSuite lte-x2-handover

PASS: TestSuite lte-x2-handover-measures

159 of 163 tests passed (159 passed, 3 skipped, 0 failed, 1 crashed, 0 valgrind errors)

zhouys@zhouys-OptiPlex-9010:~/workspace_ns3.18/ns-allinone-3.18/ns-3.18$ 

I check 1 crashed and 3 skipped tests as follows

CRASH: TestSuite devices-mesh-dot11s-regression

SKIP: TestSuite ns3-tcp-cwnd

SKIP: TestSuite ns3-tcp-interoperability

SKIP: TestSuite nsc-tcp-loss

I want to install the OpenNet by using this ns-3.18 and mininet. So, I want to know how to solve this problem and whether this error is the reason affecting the OpenNet installation. Could you do me a favor? Thanks

The skipped tests are because you haven't installed the optional network
simulation cradle. This will not affect your OpenNet installation.

If you are not using mesh (likely not, if you are trying to use
OpenNet), then the crashing test suite can probably be ignored also.
There were some issues with gcc-4.8 and the mesh code that have only
recently been fixed, and some fixed last year.

If you would really like to get to the bottom of this crashing test, I
would ask you to run this command and let me know the output:

./waf --command-template="gdb %s" --run test-runner

and then at the gdb prompt (gdb), type:

r --suite=devices-mesh-dot11s-regression

and then post the output or backtrace.

However, it is likely something that has been fixed in the meantime;
ns-3.18 is over a year old now. We ought to see whether OpenNet can run
with a newer version of ns-3.
