ns-3 example not working in optimized mode on Ubuntu 20.04 LTS #32

Closed temcdrm closed 1 year ago

temcdrm commented 3 years ago

The loadshed/runhpy.sh example works on Ubuntu 18.04 LTS, with ns-3 in either debug or optimized mode

On Ubuntu 20.04 LTS, a coredump occurs in optimized mode, but it runs in debug mode.

This example involves building loadshedCommNetwork with gcc9 on Ubuntu 20.04 LTS, against ns-3 built with gcc7 on Ubuntu 18.04 LTS. On Ubuntu 18.04 LTS, everything was built with the same gcc version and options.

For now, TESP ships with both debug and optimized builds of ns-3, and runhpy.sh configured to run in debug mode. The debug mode enables ns-3 to produce logging output, but the executables are larger and slower than in optimized mode.

@laurmarinovici, have you tried this with your updated loadshed example?

@d3j331; can you confirm if this is still an issue?

d3j331 commented 1 year ago

It works in 22.04 as optimized build using gcc11

Good enough for me; case closed.
