Latest Emacs (28.0.50)

There has been much discussion in various Emacs fora about the speed increase brought about by the inclusion of nativecomp, that is the build option --with-native-compilation. This essentially means that support has been added for compiling EmacsLisp to native code using libgccjit. Now all Elisp packages shipped with Emacs are compiled to native code, providing a noticeable out-of-the-box performance improvement.

My previously installed version of 26.3 that is still current with the base install of Pop!_OS (and that available from the apt repositories) does not have this feature.

UPDATE 2021-10-10 recompiled without --with-gnutls=ifavailable \ becasue TLS is apparently deprecated. And that led to the following error:

     gnutls

So, put it back in and compile again AFTER getting gnutls:

apt-cache search 'libgnutls.*-dev'
#==> libgnutls28-dev - GNU TLS library - development files

sudo apt install libgnutls28-dev
