安装ndn-traffic-generator遇Waf脚本与库版本不匹配问题求助

Hey there, that Waf version mismatch is a super common gotcha when setting up NDN tools like ndn-traffic-generator—these projects rely on specific Waf versions to play nice with ndn-cxx. Let’s fix this step by step:

• Uninstall your system’s default Waf
  The Waf installed via your package manager is almost certainly the wrong version here. For Debian/Ubuntu systems, run:

  sudo apt remove --purge waf
  

  Adjust the command for your distro (e.g., sudo dnf remove waf for Fedora, brew uninstall waf for macOS).

• Install the exact Waf version the script expects (2.0.6)
  You’ll need to grab Waf 2.0.6 directly and install it globally:

  # Download the 2.0.6 release
  wget https://waf.io/waf-2.0.6.tar.bz2
  tar xjf waf-2.0.6.tar.bz2
  cd waf-2.0.6
  # Install it system-wide
  sudo ./waf-light install
  

  Verify it worked with waf --version—it should output 2.0.6.

• Clean up and reconfigure ndn-traffic-generator
  Head back to your ndn-traffic-generator directory, delete any old build files, and re-run the configure step:

  rm -rf build
  ./waf configure
  

  This should now use the correct Waf version that matches the script included with the tool.

• Fallback: Use ndn-cxx’s bundled Waf
  If the above doesn’t work, ndn-cxx usually includes a compatible Waf version in its source tree. Find where you built or installed ndn-cxx, then run the ndn-traffic-generator configure command using that Waf binary directly:

  /path/to/your/ndn-cxx/source/waf configure
  

  Just replace /path/to/your/ndn-cxx/source with the actual path to your ndn-cxx source directory.

• Double-check ndn-cxx compatibility
  Make sure your ndn-cxx version is supported by the ndn-traffic-generator you’re using. Check the project’s README or INSTALL.rst for version requirements—mismatched ndn-cxx versions can also trigger weird Waf-related errors.
