Have you configured Eclipse properly?
http://www.nsnam.org/wiki/HOWTO_configure_Eclipse_with_ns-3

If you run any other scenario (e.g. the tutorials), do they run?

[amelie...@gmail.com]

yes,other examples(e.g.first.cc) is successful.and if i exchange CLOCKS_PER_SEC for a numble(e.g.1000),the result is

Hi,

This is not an Eclipse issue. This is a compiler issue.

We need to know the OS you're using. And the compiler version (terminal, "gcc --version".

CLOCKS_PER_SEC is a macro defined in <ctime> (http://www.cplusplus.com/reference/ctime/CLOCKS_PER_SEC/).

As a consequence, it must be found.

The os is ubuntu 12.04,and the gcc 4:4.6.3-1ubuntu5.

Hi,

very strange. If you build ns-3 from command line you get errors ?

Moreover, what ns-3 version are you using? (sorry, forgot to ask before).

Hi,

a couple of things.

1) I'm quite sure you did modify the example. If you modify an example, copy it into the scratch directory. Also, mention that the issue is about a modified script, otherwise we'll think that it's a ns-3 bug.

2) If the program works on the command line and not in Eclipse, then it's an Eclipse configuration problem.

3) Attributes are case sensitive... "ReferenceDistance"

Let us know if it works
