who wants libstdc++.so.7 ? (Re: gcc10 with libstdc++.so.9 (Re: gcc 8 related (Re: (gnuradio-core) libstdc++.so.9 conflicts with libstdc++.so.7

[Makoto Fujiwara <makoto%ki.nu@localhost>]

- I have changed ham/gnuradio-core/Makefile.common wants gcc10
- pkg_delete gcc7 and gcc8
- install libstdc++.so.9 version of gcc10
  (as described in previous mail, make package-install)
- make package on ham/gnuradio-core

Still getting
