How to use IDE to run and debug

[Siwei Li]

Hello,

I have downloaded ns-allinone-3.44 and built with build.py, and it seems different with the procedure in tutorial (skip building with IDEs).

Now how can i use IDE like VSCode to run and debug my code (both c++ and python) without restart downloading ns-3-dev and building.

Build.py is meant for command-line usage.
For IDE usage, follow the tutorial guides.
Configuration, build and debugging with IDEs are the whole reason I spent time porting ns-3 to CMake :D

Thank you for your reply!

So if i want to use IDEs, i have to download ns-3-dev from github by command-line "git clone" and build with Cmake Extension in VScode right?
Another question is, could you provide more detailed guidance or an accurate link for IDE usage.
