I've got a range here: mostly U60 running "in anger", a U80, E4500,
U10s, a U1, plus some museum pieces I can't find an OS for. I'm also one
of very few people who've got an SS1000E running Linux SMP, but that's
not a recent distro and because of library versions (**) I'm not sure
what if any version of FPC I could get running on it.
** When a program is built, the (Linux) linker puts the actual filenames
of the .so files it expects to find in the binary- not the names of any
symlinks. That means that once you've built a binary using standard
parameters, that binary /requires/ the same collection of .so versions
that was on the development system... I managed to get around that to
backport FPC from Solaris 10 to 8 but in general I think it's better to
start off with a version that runs and work forwards.
I wholeheartedly agree that power, and in the Summer heat, is a massive
problem. There's only so much we can afford, and even with substantial
air conditioning things can get pretty unpleasant in my workroom and the
adjacent machineroom. That's why I'm only able to offer U10s as
always-up systems, Vincent used one of those for Lazarus two or three
years ago and I've tried to test both FPC and Lazarus on Linux and
Solaris fairly regularly since.

You might find it useful to go to the Mantis bug tracker and look at the
SPARC-related bugs I've reported- use "View Issues", expand "Search",
select "Mark Morgan Lloyd" from "Reporter" then "Use Filter". You might
in particular need http://mantis.freepascal.org/view.php?id=18271 when
getting your initial FPC binary installed on Solaris 10.
When you get to compiling, you might find it necessary to use a command
line like this:
make NOGDB=1 OPT='-O- -gl'
What that does is tell it to not try to use the optional libgdb in the
fp text-mode IDE, and it disables optimisation in the compiler binary
(/not/ the compiler's ability to apply optimisation) so that if
something goes wrong you can get a useful backtrace.
On Debian, you'll need [checks] build-essential, gdb, libgpmg1-dev, and
some combination of libncurses5-dev and libncursesw5-dev. If you get as
far as building Lazarus use trunk (on SPARC) and treat libgtk2.0-dev and
possibly libqt4pas-dev as prerequisites, if those aren't available (e.g.
on Slackware) I suggest we continue on the Lazarus mailing list.
