Building for modern versions of Fedora (~ 37)

[hawkinsw]

Thank you for an impressive tool! DCE is exactly what we needed in our environment.

I am going to leave some tips/tricks here for how to compile/build DCE for Fedora (~) 37 (~beta). I am sure that there are certain parts of the process that I have overcomplicated and are not strictly necessary (e.g., (3), below) but I wanted to leave these notes here for my future self and possibly others who are interested:

1. Follow Tom's incredibly helpful recommended steps from: Ubuntu 20.04 support #110 (comment)
2. Change bakeconf.xml references from glibc-2.31 to glibc-2.36. (make sure that you [somehow] update bakefile.xml)
3. Use CXXFLAGS="-I/path/to/bake/source/ns-3-dce/ -Wno-return-type" INCLUDES_NS3_CORE="/path/to/bake/build/include/ns3.35/" additional environment variables. (Note: You should (obviously) change those /path/to/ for your environment).
4. Apply Move to Py_SET_TYPE from Assigning to Py_TYPE result gjcarneiro/pybindgen#54 to the pybindgen.
5. Apply changes to ns-3-dce for shims to the xstat family of functions that are no longer part of the libc API (PR forthcoming)
6. Apply changes to the ns-3-dce wscript for not building standalone pthread, rt or dl libraries (they are now part of the larger libc.so (PR forthcoming))

I cannot say thank you enough to @tomhenderson for all the work that he and @ParthPratim have done on this project. It's amazing!

In the future, I hope to contribute PRs for (5) and (6) and configure/distribute a Docker container with a build already generated.

Hello @hawkinsw thank you for these notes. Do you plan to provide PRs for 5) and 6) sometime soon? Also, are you a Python DCE user or just trying to get it to compile successfully?

Hello! Sorry for the late reply! Yes, I am planning on filing PRs. I am away from my desk for work travel but will followup as soon as possible! Sorry for the delay!
