Build error with gcc-11 about gr-iridium

[Sec42]

Python 3.x should be fine.

Can you try with gnuradio 3.9 and the maint-3.9 branch? To me it looks more like issues outside of our code/control.

Sorry for the delay... Now that Arch Linux officially upgraded gnuradio to 3.9.2.0, I tried compiling it again, this time getting this error:

CMake Error at swig/CMakeLists.txt:37 (include):
  include could not find requested file:

    GrSwig


CMake Error at swig/CMakeLists.txt:51 (GR_SWIG_MAKE):
  Unknown CMake command "GR_SWIG_MAKE".

And I'm getting the same erron on almost every gnuradio plugin I'm trying to (re)compile. It seems that gnuradio-3.9 dropped the use of swig in favor of pybind11, so very few older plugins work with 3.9 now. I think I have to go back to 3.8 for the time being to get a working system...

Yes, gnuradio modules have to be updated to work with 3.9 -- the gr-iridium has different branches for this exact reason. For use with gnuradio 3.9 please use the "maint-3.9" branch.

This should be solved now with 1329a6e. Solution is to use C++ lambdas as described here: https://wiki.gnuradio.org/index.php/GNU_Radio_3.9_OOT_Module_Porting_Guide#C.2B.2B_Modernization

Also fixed this for the maint-3.8 branch
