Ok, so I'm crossposting and putting a Followup there (yes, I already
said it, but I want to be perfectly clear).

Yes, this will be strange on a phone, I tried to compile things
back in 1998, but it never worked at that time :)

Thank you very much for all this information, I will look into it.

That would be me. I did it as proof of concept, I prefer reading news
ssh'ed in somewhere else (so I always have the same .newsrc on or off
phone).

It wasn't dead simple, but it wasn't the hardest. Termux provides a
fairly full Linux shell, trn is designed to compile on anything Unix
like. It's a good match, but really some of the trickiest bits might be
solved by compiling a newer newsreader under Termux.

Two gotchas I remember: Termux has bash, which is a good replacment for
/bin/sh and it has a sh, but it does not have /bin/sh.

$ which sh
/data/data/com.termux/files/usr/bin/sh
$

Meanwhile trn is pretty determined to use /bin/sh for lots of things
during config, install, and runtime.

The other thing that I ran into was no /etc/passwd and no getent() for
passwd entries. This comes up when it's trying to figure out the
username or something. But the code has a workaround already, just a bug
preventing it from being reached. I edited in a return(-1) (or similar)
and it worked.

Then there were the usual issues of compiling legacy code on modern
compilers.

$ cc --version
clang version 15.0.1
Target: aarch64-unknown-linux-android24
Thread model: posix
InstalledDir: /data/data/com.termux/files/usr/bin
$

It was probably something like adding -std=c89 to options.

But Termux had all the libraries needed, and all the terminal support
required for trn4. There might be a precompiled newsreader already in
Termux packages, I didn't look hard. (There is lynx in packages, I don't
recall if I have ever tested news: links from it, but it works for web
browsing.)

I also didn't try to get a sendmail working for reply by email, but it's
feasible. I have heirloom-mailx (aka nail) working for reading / sending
email, but I mostly just read crap like "verify your email address" and
mostly just send stuff to myself. Google would probably flag my
self-hosted email stack as super-spammy.

FWIW (mainly to Eric), in my Cygwin environment, I use ssmtp to send
email from tin. ssmtp is a send-only sendmail emulator and is much
easier - and sufficient for this purpose - than full-blown sendmail.

So perhaps Eric can get a hold of - or build - ssmtp for/in Termux.

Well, maybe I can try this, but I don't understand all you say,
and this is not only because I'm French, so I will try to understand
and it may take some time :)

Anyway, thanks to you two, there are many things I can't figure
out in tin, for example searching an article with "L" always
fails, even if this is the one I'm replying to, maybe I don't
write it properly. So making it work on termux looks like a
good idea but maybe it's too much for me, only for the moment I hope.
