I am trying to test Lazarus 1.8 RC1 (and following versions) under Raspbian Jessie with PIXEL.
But unfortunately I could not find any instructions or scripts helping to install *this* RC.
Any hint?
Regards -Joe

You could try my script for installation of FPC + Lazarus on an RPi3. http://blog.boberglund.com/install_lazfpc_local_pi.sh

In order to get the version you need just edit the script before running it and replace the versions at the top of the file with the one you want.
It will install into the pi user space rather than make a global installation using sudo.

I have not tested with the more recent Lazarus 1.8, but it worked fine with 1.6RCx and 1.6 release.

Just to check the "standard way of doing it" in case there's any surprises, with FPC 3.0.2 installed:

svn co http://svn.freepascal.org/svn/lazarus/tags/lazarus_1_8_0_RC1 cd lazarus_1_8_0_RC1
make

That worked as expected.

make clean bigide

That also worked, except that there was a message about purist woult probably object that the
binary hadn't been added to the desktop environment's menu.

That's an up-to-date "full" Raspbian (i.e. not "lite").

I made the script in order to install "everything" on a bare bones RPi with Raspbian from the install image. So it therefore also installs FPC, then Lazarus. And it uses a start compiler I made myself since I could not find any 3.0.0 FPC for ARMHF on RPi at the time. It is downloaded as part of running the script.

My apologies, but since you hadn't tested it for the current RC I assumed you'd abandoned it.

No apology needed!

It's just that I have 6 RPi:s running at home for different purposes and those I use for FPC programming are working well as it is, so I have not even looked for new releases of Lazarus recently.

The script was done for this:
1) To simplify the initial installation on a brand new RPi
2) To make sure the install is done to the pi environment rather than global with sudo.

Noted. But I'd got one next to me earmarked for development onto which I could easily checkout the RC (using the original published URL) and where I could check the build using the basic commands that the developers expected and which are probably buried somewhere in the Wiki :-)

Bo,
unfortunately, this failed with error message something could not be found. Seems, I did not edit the script the right way. What lines are to be edited and exactly how for Lazarus 1.8.0 RC1? Thanx -- Joe

Mark,
I installed FPC 3.0.2 and then followed your proposal. But the compilation of Lazarus 1.8.0 RC1 was aborted with an error message saying FPC 3.0.0 was needed.
How to fix?
Regards -- Joe

What is the exact error message?

Mattias

Make sure that the ppcarm command points to the 3.0.2 binary. Here's what I've got in my /usr/local/bin:

lrwxrwxrwx 1 root staff 12 Mar 25 14:14 ppcarm -> ppcarm-3.0.2 lrwxrwxrwx 1 root staff 31 Mar 25 14:13 ppcarm-3.0.2 -> /usr/local/lib/fpc/3.0.2/ppcarm

The fpc -v command should give you version info:

$ fpc -v
Free Pascal Compiler version 3.0.2 [2017/03/02] for arm Copyright (c) 1993-2017 by Florian Klaempfl and others Fatal: No source file name in command line
Fatal: Compilation aborted
Error: /usr/local/bin/ppcarm returned an error exitcode

I have not used the scripts in a while, the last time was when I installed on a Raspbian Pixel RPi in January-February, and at that time the script worked for me.

One note though:
The script is for installing on a bare bones RPi Raspbian and it deals with both the FPC seed and release versions and then Lazarus.

So if you are only interested in Lazarus 1.8RCx but have no need to get a new FPC then this is probably not for you.
I might set up a new Pi soon for use at my vacation home over the summer and when I do I will check the script again...

I'm sure, this will be another very useful contribution from the famous 'Developer in Sweden'. Are you using the Pi Zero W?

Hi again!
I have now returned home and been able to check the script. I used a brand new Jessie PIXEL image and did this before starting the script:
- Created dir /home/pi/bin where the fpc binary will reside
- Logged off and back on again to put this dir into the PATH

Turns out that the fpc sourceinstall command on line #150 fails because there is no current path to the seed compiler ppcarm.... So I have added option FPC=<path to ppcarm> on that line and with that done the script runs OK to the end and Lazarus is available on the main Jessie menu below "Programming".

The corrected script is found here:
http://blog.boberglund.com/install_lazfpc_local_pi.sh

Regarding configuration, these lines need to be handled by editing the versions mainly (lines #32 and #43-46):

LAZDESK=/home/pi/.local/share/applications/lazarus_1.6.2.desktop FPCTAG=release_3_0_0
FPCVER=3.0.0
LAZTAG=lazarus_1_6_2
LAZVER=1.6.2

In your case change them to this:

LAZDESK=/home/pi/.local/share/applications/lazarus_1.8.RC1.desktop FPCTAG=release_3_0_2
FPCVER=3.0.2
LAZTAG=lazarus_1_8_0_RC1
LAZVER=1.8.RC1

No, I am buying the RPi3 now but have a number of earlier generation Pi running their tasks also. I want the most performance I can get out of them.

Bo, helps a lot. Very kind. Have a nice day.

On a Raspberry Pi Zero W, the script failes with this error:

(9009) Assembling buildprojectdlg
buildprojectdlg.pas(603) Error: (9008) Can't call the assembler, error -1 switching to external assembling
buildprojectdlg.pas603) Fatal: (10026) There were 2 errors compiling module, stopping

I had selected the option 'for all Pis'.
Could it be a swap file size problem? On the Pi Zero W, the default size is 100 MB.

Joe

Yes, assume you need at least 512Mb. Put a temporary swap partition onto an external USB stick or whatever.

.
.
I'll give it 1024 MBytes and a try.
Thanx -- Joe

Then, on a Pi Zero W, I prepared a brand new Jessie PIXEL image on a 32 GB card and
- Set Locale Settings to Germany and WiFi settings
- Created dir /home/pi/bin
- Logged off and back on again to put this dir into the PATH
- Enlarged the swap file size from 100 MB to 1024 MB, stopped and restarted swapfile

On Pi Zero W, using the ARMv6 option and De-de locale, i get this error message:

What does this say? How to fix?

It says it can't find the compiler binary. Hopefully Bo will be able to give you some direct help, but the classical way of fixing it would be by something like

make clean all PP=ppcXXX

.
Went to /home/pi/dev/fpc/3.02 and did make clean all PP=ppcarm. Got "An unhandled exception occurred at $000678A0". Maybe the ARMv6 CPU got some ARMv7 code?

You should probably use this instead:
make clean all PP=/home/pi/dev/fpc/ppcarm
because my script downloads the seed compiler (ppcarm ver 3.0.0) to the base fpc directory in which there are the version subdirs like 3.0.2 and the only files are supposed to be the relevant ppcarm compiler binary.
