Description Nicola Baldo 2011-05-03 05:03:20 UTC

./waf distclean
./waf configure --enable-tests --enable-modules=spectrum
./waf

[snip]
Waf: Leaving directory `/home/nicola/locale/ns-3-dev/build'
Build failed: Missing node signature for [bld:///home/nicola/locale/ns-3-dev/ns3/point-to-point-module.h] (for implicit dependencies 
	{task: cxx config-store-file-bug.cc -> config-store-file-bug_2.o})

I guess this is a dependency problem, trying to sort it out

Comment 1 Nicola Baldo 2011-05-03 05:12:30 UTC

I checked the Spectrum code but I could not find any dependency on neither the point-to-point module nor the ConfigStore (both are mentioned in the error message). 

Maybe a bug in the modular build system?

Comment 2 Nicola Baldo 2011-05-03 05:25:38 UTC

works with the following:
./waf configure --enable-tests --enable-modules=spectrum,point-to-point

but I really can't find why spectrum should depend on the point-to-point module...

Comment 3 Nicola Baldo 2011-05-03 06:39:11 UTC

Created attachment 1103 [details]
workaround

this patch adds to the spectrum module a dependency on the point-to-point module.

Comment 4 Nicola Baldo 2011-05-03 06:41:48 UTC

raising to P1 since I think we should really fix it before the release.

Somebody please tell me if the workaround shall be pushed or something else should be done.

I can't reproduce this.  I just tried this on the tip of ns-3-dev 058f6ecace0c
./waf configure --enable-modules=spectrum --enable-tests

and I got:

Modules built:
applications              bridge                    config-store             
core                      internet                  mobility                 
mpi                       network                   propagation              
spectrum                  tools

but no point-to-point.

spectrum pulls in internet, propagation, applications

internet pulls in bridge, mpi, network, core

applications pulls in config-store and tools             

propagation pulls in mobility, so I think they are all accounted for.

I just repeated after a distclean.

Comment 6 Nicola Baldo 2011-05-03 13:00:40 UTC

sorry, my fault... I didn't realize I had a bogus file in scratch/
I confirm that it works correctly with 7124:058f6ecace0c
my apologies for the noise
