Created attachment 3087 [details] Patch for the top level wscript Overview: If one of the dependencies in one of the wscripts of one of the modules contains a spelling error, "./waf build" will encounter an endless loop and run indefinitely. The attached bug fixes this. It Steps to Reproduce: 1) Go into the folder of one of the modules, e.g., mobility. 2) Open the wscript in that folder. 3) Introduce a spelling error in one of the dependencies. For example, if you chose the mobility module replace "mobility = bld.create_ns3_module('mobility', ['network'])" by "mobility = bld.create_ns3_module('mobility', ['networks'])". Note the additional 's' after 'network'. 4) Go back to the ns-3 root folder and call "./waf build" Actual Results: The system runs indefinitely. Expected Results: The system should detect the unresolvable dependency, stop and print an error message. This is what is done by the attached patch. Build Date & Hardware: ns-3.27 and ns-3.28 on Mac OS X. Additional Builds and Platforms: none tested. Additional Information: none.
