I'm getting results from a package which differ from results that I got
a few weeks ago, and the only thing that I can think of that's changed
is the version of R (from 4.1.0 to 4.4.1).
So I wanted to install 4.1.0 and play around with that, to see if that
is indeed the explanation. (If that is so, a whole new set of
questions would be raised, but let's leave that for the moment.) I
downloaded the tarball and set about installing 4.1.0 from source. But
the configure step threw an error, as given in the subject line of
this message. The error went on:
> configure: error: libcurl >= 7.28.0 library and headers are required
> with support for https
A bit of web searching turned up the advice to re-install curl
sudo apt-get install curl
but when I did that I was informed that:
> curl is already the newest version (7.68.0-1ubuntu2.6).
Has anyone got any *useful* advice? If so, please present it
in very simple terms if you can. (I am a Bear of Very Little Brain,
and long words bother me.) A step-by-step recipe would be appreciated.
I'm running Ubuntu 20.04, with a Mate 1.24.0 desktop.
Grateful for any pearls of wisdom.
P.S. The config.log file seems to be full of stuff relating to errors
from "openssl.c" but this is *way* beyond my pay grade.
