Unable to compile Lazarus on raspberry pi

[Johan]

Hi

I am trying to compile Lazarus on my raspberry pi. I have the raspian image installed and updated. I have installed fpc 2.6.0 from the repositories, but the repo only has lazarus 0.9.30. I want to compile Lazarus 1.0.2 but the compile fails near the end with the following message:

Free Pascal Compiler version 2.6.0-6+rpi1 [2012/11/16] for arm

I can compile normal (non - gui) freepascal apps without issues.

Any ideas ?

I think you are using the Debian repo, so it is so old.
Have you ever tried with the latest svn trunk?
You can follow the following page.

Thanks.

I am using fpc 2.6.0 which is the current stable version. I also downloaded Lazarus 1.0.2  source and tried to compile that. I have in the meantime managed to compile a Lazarus project and it runs. I just cannot seem to compile the IDE.

hi i have same problem you must install binutils-dev

Code: [Select]

sudo apt-get install binutils-dev

[chrnobel]

Code: [Select]

sudo apt-get install binutils-dev

I am also facing the same problem, and installing binutils-dev does not make any difference.

The reason for me to compile the ide is only at I want to install the Zeos package - anyone having any ideas?

I used to increase swap file and then managed to compile Lazarus 1.0.2 from the source (latest SVN at the time) on my old 256MB Pi. I am not sure, but I think I have increased swap to 512MB. I can check when I get home if anyone is interested. X was not started. I used FPC 2.6.0 from repository.

Combining lazarus with a debian version( wheezy raspbian) of linux on a raspberry pi provides a huge number of opportunities for a bad outcome. The raspberry pi folks have addressed this with pre validated packages. So if  using these packages has value to you ....here are the steps.
 
1) get ready to update the pi OS

The following commands can take about 2 hrs to complete
 
  sudo apt-get update              //// gets latest version of pi OS
  sudo apt-get upgrade             //// upgrades to the latest version
2)
  get ready to install fpc

  sudo apt-get install fpc         //// this often fails
3)
  If 2) fails
  sudo apt_get update
  sudo apt-get install fpc        /// should now work

4)
 Get ready to install lazarus
 
  sudo apt-get install lazarus

At this point the lazarus IDE should run.
Now the raspberry pi OS distro is for a 2gb SD card. ( even an 8gb card will only get a 2gb partition) Use Win32DiskImager.exe( to R/w linux image) and a partition manager to expand the linux partition space...I run lazarus on a 8gb sd card pi is 512MB rev B

@picstart.

Which is exactly what I have done.

And there is no problem in installing FPC + Lazarus.

BUT, the problem comes when one wants to install additional packages (eg. Zeos), which requires the IDE to be rebuild  - then the compilation fails.

[picstart]

I did install bgracontrols and other components that I wrote myself and the IDE did recompile without error but it was slow ( several minutes). Now you may have a dependency issue between the zeos and the version of lazarus it will run on....further the version of lazarus that will run zeos may not run on the pi. Opportunities to encounter issues like this exist with every new version of lazarus or the linux pi OS. Fortunately these opportunities are free opportunities.

Ok, then lets turn it the other way - does anyone have any luck in installing Zeos on the Pi, and if so, how do one have to do?

[gigi0ne]

first sorry for my english..

try this:

insert a usb key (without data)

df

see key name (for me sda1)

umount sda1
mkswap /dev/sda
swapon /dev/sda

then recompile..
recompile perfect.. slow.. very slow.. but work

OK, to answer my own question.

There are some problems with recompiling the IDE on the RPi, as it simply requires to much memory, but I have found a way following this guide:

http://www.michellcomputing.co.uk/blog/2012/11/lazarus-on-the-raspberry-pi/

I reduced the size of GPU to 32M, and increased the swap file to 500M (running raspi-config).

Then it is possible to build the IDE from the console, before starting X - trying under X uses to much memory.

Then to install the Zeos package as I needed, do like this in CLI:

./lazbuild --build-ide= ~/(eventual subdir)/zeos701/packages/lazarus/zcomponent.lpk

Hi!
Chernobel

I am trying your message about compile Lazarus on Raspberry PI. I use the Mitchel guide and everything was fine , Lazarus run on my PI, but when I try to install Zeos uisng lazbuild --build-ide=component,
I get an error

TExternalToolList.Run : Error: Illegal parameter

U have any cluee?

I've lost half a day trying this tutorial and failed (error from the first post, then some errors while building Lazarus) I'm guessing that people who did it successfuly, did it not on the "fresh" system, but installed something additional before, what wasn't mentioned in the tutorial.

There's a link to my step-by-step no-nonsense guide on compiling and building both FPC and Lazarus on the RPi2 in this forum post: http://forum.lazarus.freepascal.org/index.php/topic,27257.0.html
