The "./configure" part of the installation of sage advice this:
database_cremona_ellcurve-20190911: optional, use "./configure
--enable-database_cremona_ellcurve" to install
Therefore, if I were you, after updating the source tree with git let's
say, I would do:
make configure
./configure --enable-database_cremona_ellcurve
MAKE='make -j8' make
to compile sagemath in parallel such a way that it automatically installs
the desired optional packages in whatever ordering respecting the
dependencies which works.
You may also want more such "enable" as follows:
./configure \
--enable-experimental-packages \
--enable-download-from-upstream-url \
--enable-ccache \
--enable-database_cremona_ellcurve
You may consult the config.log file which lists a lot of them.
Sincerely,
Sébastien
