Thought a status report might be useful here. Using Raspbian 4.1
"Jessie" dated 2015-11-21 from
https://www.raspberrypi.org/downloads/raspbian/ I find fpc_eabihf_3_0_1
from http://sourceforge.net/projects/mseide-msegui/files/fpcarm/
installs and runs with no further prerequisites, and is able to build
the standard 3.0.0 sources. There are some minor complaints that
Subversion is missing, but that can be trivially fixed.
The new Jessie "Lite" similarly runs 3.0.1 and builds 3.0.0, there are
no missing prerequisites so it is not necessary to start off at 2.6.x.
On "full fat" Jessie, Lazarus 1.4.4 compiles but requires libgtk2.0-dev
as a prerequisite. The result doesn't run reliably but this is a Jessie
issue which I believe is being addressed. Adding libqt4pas-dev and
building Lazarus for Qt results in something that works fine.
I have not tried building Lazarus on Jessie Lite, since I see it as
mainly being useful for embedded systems based on the original Rpi or
the new RPi Zero. I don't anticipate significant problems other than
caused by limited memory (Lazarus requires at least 512Mb RAM+swap to
build).
Using standard RPi2 Debian (i.e. not Raspbian) from
http://sjoerd.luon.net/posts/2015/02/debian-jessie-on-rpi2/ with the
addition of a fairly standard collection of packages using tasksel
followed by the build-essential, gdb and subversion packages runs 3.0.1
and builds 3.0.0 in essentially the same way as is described above.
On standard RPi2 Debian, FPC 3.0.0 fails to build Lazarus 1.4.4 with
errors like
paswstring.pas(425,46) Error: Incompatible types: got "procedure(PChar;var UnicodeString;LongInt);StdCall>" expected
"TUnicodeStringManager.procedure(PChar;Word;var UnicodeString;LongInt);StdCall>"
paswstring.pas(439) Fatal: There were 4 errors compiling module, stopping
Fatal: Compilation aborted
Makefile:2276: recipe for target 'lazutils.ppu' failed
I'm not intending to pursue this at the moment, since I've hacked a lot
of stuff onto the top of the supplied "lean and mean" distro ("Adde
parvum parvo magnus acervus erit") and my guess is that the Unicode
stuff is inadequately configured probably impacting on FPC. I mention it
here entirely as a "heads up" for anybody attempting a similar combination.
In all of the above cases, /etc/fpc.cfg should contain a line
-Fl/usr/lib/gcc/arm-linux-gnueabihf/4.9

An attempt to do an update/upgrade/dist-upgrade also failed, leaving it in a broken state with e.g. the display manager deinstalled and not installable. So I'm very grateful for Jonas's help and patience, when he could easily have told me to get lost and fix the system software. I anticipate that once I'm working from the current (2015-05-05) Raspbian that things will be much easier. However it looks as though the people who put the older version together left it in a state where the metadata was broken or inconsistent, which was possibly unavoidable taking into account that source.list and sources.list.d identify three distinct repositories (debian.net, qmh-project.org and raspberrypi.org). Incidentally (and I hope that the ML managers will excuse the digression), if anybody has a plugtop USB PSU badged "MW" with their Rpi I strongly suggest checking that it's robustly assembled: one of these came apart when I tried to unplug it and I found that it was held together only by silicone RTV sealant.

Re: [fpc-pascal] FPC 3.0.0-rc1 release
Not clear about rpi compilers for rc1. My testing on rpi 2 of Martin's 3.0.0 of 18th Aug (similar to rc1?) suggests that compilation works ok, but linking doesn't. So does this mean that 3.0.0 doesn't have a working fpc for rpi 2? What about rpi 1? I have both rpi 1 and 2 available, so let me know if I can help with more testing.

We don't need to mention the arm flavour, except in the details, any more than we mention the instruction set of i386 with all their variants.

Unfortunately, deadstore will be difficult to debug with the actual code

Since it shouldn't affect too much code, it would be worth a try to
compare the generated assembler with and without {$optimization

On Unix-like platforms, you have to use ./ppcarm to execute the ppcarm binary in the current directory instead of the one in the PATH. The reason is that many Unix systems are (or can be) multi-user and that e.g. the /tmp directory is writeable by everyone, so if someone would put a program called ls in /tmp that was malevolent, a lot of users would be caught by that.
