Hi,

on a Pi 3B+ under Stretch I did this:

~ $ mkdir lazarus-2a
sudo chmod a+w lazarus-2a
svn co https://svn.freepascal.org/svn/lazarus/trunk lazarus-2a cd lazarus-2a
make clean all

I get this error message:
...
Compiling fcllaz
home/pi/lazarus-2a/packager/registration/fcllaz.pas(11,3)  Fatal: (10022) Can't find unit db used by fcllaz
Fatal: (1018) Compilation aborted

What's wrong?
BTW: fpc -iW returns "3.0.4".

Have you tried "make OPT=-vt" to see why fpc can't find unit db?

Check that your /etc/fpc.cfg contains the right -Fu paths.

/etc/fpc.cfg -> /etc/alternatives/fpc.cfg -> /etc/fpc-3.0.0.cfg

It seems, something is wrong with upgrading from fpc 3.0.0 to fpc 3.04. What's the official method to do this? I did sudo apt-get upgrade.

cat /etc/fpc-3.0.0.cfg (first for of 278 lines):

Debian supports installing multiple fpc versions.
Create a /etc/fpc-3.0.4.cfg and change the
symlink /etc/alternatives/fpc.cfg

Mattias

Joe,

Either your fpc config environment is wrong or you are running out of memory. First read this message from the mailing lists:

http://lists.lazarus.freepascal.org/pipermail/lazarus/2016-April/162928.html

To change GPU memory run "sudo raspi-config" and go to Advanced Options then Memory Split. Set the value to 64 or 32 then reboot and try to recompile.

If you still have problems compiling, let me know and I'll post a proper raspberry build script.

Yes, Anthony, please send this script (very appreciated). To the GPU 64 MB are assigned.

I made this cfg file with fpcmkcfg and changed the symlink with ln -sf /etc/fpc-3.0.4.cfg /etc/alternatives/fpc.cfg,
but 'make clean bigide' still fails with message "Can't find unit db used by fcllac".

Does this 'make' work on your Raspi 3B+?

I'll post a build script in a little while. I have to reconfigure another SD raspbian image because my current one is dedicated to another project. Hang in there.

Do you refer to the content of the cfg file? I created the cfg file automagically with "fpcmkcfg -o /etc/fpc-3.0.4.cfg", but have no idea about its content and did not change anything in it.

In the meantime, to be sure fpc 3.0.4 is ok, I updated its sources (to revision 41293) and did "make build" and "sudo make install". No errors.

But when trying again to make lazarus, still the same error message pops up. How does it work on your  Raspberry Pi 3B+?

Regards --  Joe

Okay Joe, I've create a version of Lazarus 2.0 and it's available here:

https://www.getlazarus.org/setup/?download#raspberry_pi

Please see this mailing list message titled "Raspbian FPC 3.3.1 and Lazarus 2.0 Available" for the notes.

I made this a precompiled bundle rather than an svn build script because it takes MUCH longer to download and build sources on a Raspberry Pi, and also I've reduced the storage footprint by at least 1.5GB, which is a lot given the typical space people have available on their Raspbian SD card.

Let me know if you have any questions or problems. -------------- next part --------------

Hi, Anthony,

unfortunately this script fails on a Pi3B+ with  a fresh installed Stretch (Version Nov 2018).
I have created a bug report with enclosed screen shot and tried to send it to you, but got this answer:

Your mail to 'lazarus' with the subject

Re: [Lazarus] Raspbian FPC 3.3.1 and Lazarus 2.0 Available/Bug Report

Is being held until the list moderator can review it for approval.

The reason it is being held:

Message body is too big: 161273 bytes with a limit of 100 KB

I am going to make the screen shot smaller and to try again.

Regards -- Joe

I have created a script file to use for installing fpc + lazarus on RPi platforms including the dependencies and build tools. I have used it many times on pristine RPi builds and it always worked fine for FPC 3.0.0 to 3.0.4 and Lazarus 1.6 to 1.8.x
I have put the script on my website for simplicity (so I can wget it into a new RPi easily).

After reading this post I puilled out an RPi3 unit I had used for other stuff so there was no old fpc/lazarus files on it and it was running stretch too.

So this is what I did:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

Then I manually created the user bin dir at /home/pi/bin since this is where my script deposits the binaries. I also logged out and back in to make sure this bin dir was recognized as the user's bin and was on path.

I then created a ~/dev dir for my tools and downloaded my build script into it using wget and configured the script regarding versions so that fpc 3.0.4 and lazarus 2.0.0 would be the targets for installation.

What happened when I ran the script is that it seemed to go OK as far as all dependencies, subversion etc being installed and fpc 3.0.4 compiled and set up for use.
But the last steps where lazarus was to be installed ended after 37 minutes total with this message:

(9009) Assembling sourceeditor
sourceeditor.pp(11384) Error: (9008) Can't call the assembler, error -1 switching to external assembling
sourceeditor.pp(11384) Fatal: (10026) There were 2 errors compiling module, stopping

make: *** [idebig] Error 2
install_lazfpc_local_pi.sh: 174: Cannot make Lazarus bigide! Aborting

I wonder at what step you are getting the missing db error?

And of course I wonder what was the reason for my failure?

I found the problem!
Swap size had not been increased on this RPi3 image! After changing to 1024M swap I ran my lazarus-only install script (it is a cut-down version of the original script) and it finished OK after 13 min and the Stretch menu was updated to include Lazarus 2.0.0 in its Programming section.

All is well and good, so I am not able to help the OP with any other advice but making sure his swap is set to 1024 MB.

Bo,

Buliding Lazarus pushes the limits of the hardware and default settings for Raspbian. The 1GB of RAM on the Pi is often not sufficient to build Lazarus. Typically you need to create modify the swap to be 512MB or 1GB. I recommend 1GB.
