[fpc-pascal] Cross-compiling

[Kevin Lyda]

tl;dr Is there a docker image(s) with an fpc compiler that supports a slew
of platforms?

For April Fools Day this year I released a command.com shell for Unix[0].
It included a version of the Turbo Pascal 3.0 "IDE" and it was released for
a slew of platforms. This is rather easy to accomplish with the go tool -
you just set some environment variables and it works.

I'm winding down my career and have a number of fun projects in mind. My
goal this year was to release one written in Pascal - one that would be
fun, but also hopefully useful. But I ran out of time so I did the simpler
Go one. Now that I've slipped the release date a year I'd like to make sure
I can release it just as polished as I did for the silly one I did this
year. And part of that involves releasing for all the mainstream OS's:
linux, freebsd, openbsd, netbsd, ilumos, aix and darwin.  And also all the
mainstream architectures: riscv64, arm64, ppc, i386 and amd64. Now, fpc
might not support all thes, but it likely supports many of them and I'd
ideally like to build them all in one runner. I can install the forgejo
runner on a slew of libvirt machines and configure them all, but that's a
rather heavy solution.

I'm working on building an fpc cross compiler[2] for a number of
architectures, but am I triodding well-trodden ground? Does something like
this already exist? I can't find anything, but maybe I'm not looking in the
right places. What I've built[3] supports:

fpc -Px86_64     -Tlinux
fpc -Paarch64    -Tlinux
fpc -Parm        -Tlinux
fpc -Pi386       -Tlinux
fpc -Ppowerpc64  -Tlinux
fpc -Pmipsel     -Tlinux
fpc -Px86_64     -Tfreebsd
fpc -Px86_64     -Tnetbsd
fpc -Px86_64     -Topenbsd

I think I'd need to do darwin on an actual Mac and not sure what other
architectures are supported for the *BSDs.  It's a large container as it is.

As an aside, if there's someone out there wanting to collaborate on a TUI
application that would have a filesystem focus, please reach out.  I'm not
close to that part, but I might be later in the year and I've honestly
never made one.  Alternatively, if folks could suggest good tview TUI
applications to read, that would be great.

Thanks,

Kevin
