Description Hemant 2011-08-01 04:42:20 EDT

Hi,

While following the installation and testing of NS3 as given in http://www.nsnam.org/wiki/index.php/Installation and http://www.nsnam.org/wiki/index.php/Troubleshooting, when I run ./test.py, I come across the following errors. Kindly help.

Waf: Entering directory `/home/lab/repos/ns-3-allinone/ns-3-dev/build'
Waf: Leaving directory `/home/lab/repos/ns-3-allinone/ns-3-dev/build'
object 'ns3-network--lib' was not found in uselib_local (required by 'bench-packets')
Waf died. Not running tests

Prior to running ./test.py, I executed 

./waf configure --enable-examples --enable-tests --enable-modules=core

and the output I had received is as follows:

That's because utils/wscript tries to build bench-packets along with the test-runner, and bench-packets requires the network module to be enabled.

Any particular reason you need to do a build with just 'core' enabled?

Comment 2 Hemant 2011-08-01 05:21:58 EDT

Thanks Suresh. If I execute ./waf configure --enable-examples --enable-tests instead of ./waf configure --enable-examples --enable-tests --enable-modules=core, then ./test.py does not give any problem. All 174 tests are passed successfully.

Thanks.

wscript says this:

    obj = bld.create_ns3_program('bench-packets', ['network'])
    obj.source = 'bench-packets.cc'

but build is failing on this program when only 'core' is enabled

I'm not really good with the build system stuff, but here's my hunch:

- In the top level wscript, the code block between line 727 and 734 is what decides whether a program should be built or not depending on whether the dependencies for that program have been built.
- Line 795 is where the utils/ folder is added to the build list, and no dependency checking is performed after that point.

I guess the reason this went unnoticed for so long is that no one really does a build with only 'core' enabled (and no 'network'). :)
