问题
I have installed ns2. Now on terminal, ns gives % and nam gives this error. (It is supposed to pop up an animation window).
child killed: segmentation violation
Also, when I did the last step i.e., ./validate, I found this at the end.
validate overall report: some tests failed:
How do I solve this?
回答1:
The only nam version that causes 'Segmentation fault', is the nam package(s) you get from from Ubuntu or Debian : Bug report, March 2014 https://bugs.launchpad.net/ubuntu/+source/nam/+bug/1376970 .... The packages were never rebuilt / replaced.
Usable packages, see post #2 here .... .... http://www.linuxquestions.org/questions/linux-newbie-8/ns-stop-couldn't-execute-nam-permission-denied-while-executing-exec-nam-4175524760/#2
If Ubuntu, please download a package for your OS, click the package, and it will be installed.
About "validate, some tests failed" : Please ignore. Some tests will most often fail. And always with a 64bits OS. I have never seen any of those fails causing simulations to fail.
