I am working on NS3 and I am using the ./ns3 cmake wrapper to run my .cc files. The issue is that the ns3 builds all the dependencies every time i run a file, even when there are no code changes. Is this expected? This is really hogging my time and I see in the NS3 manual that it should not build every single time, and builds only what is necessary
The behavior you report should not be happening, especially if you are using the latest ns-3.36.1 release. If it is with that release or later, please file an issue with enough details for a maintainer to try to reproduce the issue. In any case, you can suppress even checking whether a new build is needed by passing the --no-build option to ./ns3 run command.
