Raspberry pi lazarus compile problem

[croc]

Hello,

I have question. I have raspberry pi version with 256mb and 16gb sd kaart. I installed lazarus and it boots up correctly in GUI. When I compile a simple example hello world I get the following error: lazarus error can't call the assembler, error -1 switching to external assembling.

I already change the memory split to 16mb with
sudo raspi-config option 8 memory split to 16mb.

What should be done to fix this problem ??

[croc]

I have now a different error.

Can not find unit interface used by Hello_World. check if package LCL is in the dependencies.

How could I fix this?

[croc]

I got the first problem back and again.

The version of lazarus is Lazarus IDE v1.2.4+dfsg-2+b1

Can somebody help me ??

Did you install Lazarus and fpc via sudo apt-get or did you compile the tools from source? Which Free Pascal version do you use?

[Paul Breneman]

I don't know what went wrong, but because of your "switching to external assembling" error you should probably install the binutils package.

[croc]

If I do sudo apt-get install binutils

I get the following message: binutils is already the newest version.

So I think this will not be a problem.

Can somebody still help me ?

I installed the version from jesse lazarus and fpc version from here: http://forum.lazarus.freepascal.org/index.php/topic,20481.msg141721.html#msg141721 .

it is the Lazarus IDE v1.2.4 +dfsg-2+b1

Free pascall is version is I think this one
When I ask: dpkg-query -W -f='${Status} ${Version}\n' fpc
the following answer:
Install ok installed 2.6.4+dfsg-4+rpil

When I ask: dpkg-query -W -f='${Status} ${Version}\n' binutils
the following answer:
Install on Installed 2.24.90.20141023-1

When I ask: dpkg-query -W -f='${Status} ${Version}\n' lazarus
the following answer:
Install ok Installed 1.2.4+dfsg-2

So I hoop this will help.

A while back I had problems using FPC 2.6.4 on ARM Linux:
http://forum.lazarus.freepascal.org/index.php/topic,23927.msg148329.html#msg148329

[croc]

I am now removing the fpc 2.6.4 with the following command:
sudo apt-get purge fpc 2.6.4.
this will take a time.

Than I will use
sudo apt-get update
sudo apt-get upgrade
hope this will work
sudo apt-get install fpc 2.6.2

And check if this will help or do you don't this will work Paul Breneman?

[Paul Breneman]

I would recommend not removing anything.  I was not using Lazarus in my project so I'm not sure how it would be affected.  Maybe someone who knows will jump in and let us both know?

[croc]

It looks like the raspberry pi install again the newest one after the command sudo apt-get install fpc 2.6.2.

is there way to resolve this to install only the 2.6.2 version ?

[croc]

Oke Paul.

I will wait than till it will be finished the install version 2.6.4 again.

Is it possible you have a image with the lazarus install the 1.2.4 version on raspberry pi for me ??

So I can already create some apps on it, till somebody will resolve this problem.

I see that I have some error in the package graph.

When I build IDE with: tools -> configure "build Lazarus".... -> 
LCL widget type = gtk (deprecated,
Target OS: = Linux,
Target CPU: arm
and only Clean up on = Automatically

and than build I get the following error:
Brokken dependency: One or more required packages were not found. See package graph for detials.

I get Package graph. see attachement

[croc]

I have a working version now

  sudo apt-get update             
  sudo apt-get upgrade   
  sudo apt-get -f install
  sudo apt-get update
  sudo apt-get upgrade         
  sudo apt-get install fpc     
  sudo apt-get install fpc-source
  sudo apt-get update
  sudo apt-get upgrade
  sudo apt-get install lazarus

don't forget to install sudo apt-get install fpc-source otherwise lazarus will complain source is missing.

# apt-get install subversion
# svn export http://svn.freepascal.org/svn/lazarus/trunk/components/leakview/leakview.lpk --revision 47172
# mv leakview.lpk /usr/lib/lazarus/1.2.4/components/leakview/
# svn export http://svn.freepascal.org/svn/lazarus/trunk/components/leakview/dbginforeader.pas --revision 47172
# mv dbginforeader.pas /usr/lib/lazarus/1.2.4/components/leakview/

Now Lazarus should work, but the IDE may complain about a broken ide/version.inc
In this case, just look at the title bar and edit /usr/lib/lazarus/1.2.4/ide/version.inc (I edited mine from '1.2.4+dfsg-1' to '1.2.4+dfsg-1+b1')
Restart Lazarus and everything should work!

The Raspberry Pi doesn't have enough memory to recompile the whole IDE, so you need to add a swap
Take an empty USB memory (at least 1GB) and insert it in the Raspberry Pi

$ df

Find which /dev it is (for me it was /dev/sda1)
WARNING: THIS WILL DELETE EVERY FILE ON YOUR USB MEMORY

$ sudo umount /dev/sda1
$ sudo mkswap /dev/sda1
$ sudo swapon /dev/sda1

Now you have a good amount of swap memory; you can check it with

$ cat /proc/swaps

Now start the IDE with root permissions

$ gksudo lazarus-ide

Uninstall package tachartfpvectorial 1.0 in lazarus when you see the IDE

for me this resolve the problem.

I still have package errors after uninstall when I try to rebuild the IDE maybe somebody can help me with this??

Till now this is better than nothing

If you have enough space on your sd-card you can also use the space that is on the sd-card.

instead to add the usb stick sda1 you can also do this.

sudo nano /etc/dphys-swapfile
change the value
CONF_SWAPSIZE=100 to CONF_SWAPSIZE=1024

the following steps is needed
sudo swapoff -a
sudo dphys-swapfile setup
sudo dphys-swapfile swapon
sudo swapon -a

you can check with sudo top command and next to KiB Swap: you will see the total swap space.
