Hi all,

I'm a newbie about cross compiling, but I need to develop some applications for arm-linux architecture. There are many days that I search on web tutorials, guide and simple sparse bit of knowledge about how to to... but no references to tutorials I found are very old and partially not working.

So I hope that you can help me to write a generic step by step tutorial, starting from "generic" sources; I mean what to download, what to write in terminal, etc...

What I believe to know is that:
1) cross compiling for arm-linux is simplest from Linux X86
2) I need binutils ( I downloaded latest one:
http://ftp.gnu.org/gnu/binutils/binutils-2.20.tar.gz )
3) I need sources of fpc and lazarus. I downloaded:
- latest official fpc: fpcbuild-2.2.4.zip
- Lazarus snapshots: e.g. today's lazarus-0.9.29-22952-20091204-src.tar.bz2

Now knowledge is even more darkness... I tried to install binutils:

cd ~/temp/buinutils
./configure
make
sudo make install

My experience with linux is not very deep, so I don't know if it is installed right.

After this, do I need to compile fpc and than lazarus? How?

I became crazy... I think I will never develop for arm-linux without your step by step help...

Thank you very much in advance!

2009/12/4 :

This will give you the binutils for your architecture and that's probably not what you want. You need to cross compile the binutils first, so you need to make distclean in your binutils directory, then ./configure --target=arm-linux. You probably also want to use --prefix to control where the files get installed (I think /usr/local is the default).

That's just the beginning, though, and if you need to use libc (like with lazarus), you need to cross build that, too.

So, it's a lot easier to get the cross tools for the specific distribution your arm board is using. Some distributions have a "master makefile" that auto automatically build the cross compilers and binutils. If you've bought an arm development kit, the vendor usually supplies this for you. See if you can find this before you attempt to build fpc. Also note what c library your arm system is using (e.g. glibc, uclibc).

I've used fpc on arm-linux, but never lazarus, since I've never seen an embedded board with gtk libs on. Some of them have qt, though, but ymmv. As far as graphics go, I've managed to use fpgui, since it talks to the x libraries directly and is very light weight.

2009/12/4 Henry Vermaak :

Ok, thank you!
I tried to do:

make distclean
./configure --target=arm-linux
make

but I get some errors:

~/arm/binutils$ make

make[1]: Leaving directory `/home/kjow/arm/binutils' make: *** [all] Error 2

I need to develop for Maemo platform (Nokia N900), it is a GNU/Linux distribution based on Debian (arm) with X11 and all other things of desktop version. There is a specific development kit, but it can run any arm-linux compiled program (I read that in past versions, some people have cross compiled for it)
I would to have a lazarus configured like for arm-wince, so multiplatform will be fantastic!

Thank you!

The makefiles of GNU binutils are broken: if you compile for another target, distclean is not enough, just delete the whole binutils source dir and unpack it again.

Ok, I deleted binutils directory and re-unpacked it, then I did again:

./configure --target=arm-linux
make

It started to make a lot of compilation rows, until these last rows:

I think that are not very comfortable these errors... what's wrong?

Odd, it seems to work for me, but I'm on 2.19.

Note this.

You can probably fix this with passing --disable-werror to ./configure.

I think that are not very comfortable these errors... what's wrong?

I'm still not sure why you are messing around with binutils. You need to build for maemo, so just download the maemo sdk, read the manual, then try and cross compile fpc and lazarus. Relevant links are:

http://www.forum.nokia.com/Tools_Docs_and_Code/Tools/Platforms/Maemo/ http://maemo-sdk.garage.maemo.org/user-guide.html

Henry

2009/12/5 Henry Vermaak :

Perfect!

./configure --target=arm-linux --disable-werror
make
sudo make install

and now I have:

/usr/local/bin/arm-linux-as
/usr/local/bin/arm-linux-ld

So, I think that binutils are compiled right!

Because Maemo runs "pure" arm-linux programs and I know that Lazarus/fpc can compile "pure" arm-linux programs... What I know (docs are very few) is that to compile for arm-linux I need to use binutils that make utilities to generate arm-code... I know that I'm a lot confusing... but docs are very few...

e.g. here: http://wiki.lazarus.freepascal.org/Setup_Cross_Compile_For_ARM

It starts from arm-linux-fpc and than ARM-binutils, but everything is very old and there isn't any precompiled package (such as arm-wince) so I must do all myself, but there isn't tutorials or explicative/step by step documents...

Thank you!

2009/12/6 Kjow :

It's true that fpc does not need any of the gcc tools, but since you want to use lazarus, you'll need cross compiled libs of the widget set and libc. If you use the sdk, you get these for free. The way you are going now, you'll eventually need to cross compile those libraries, too.

Henry

2009/12/6 Henry Vermaak :

At moment I don't need particular feature of maemo/N900... I simply need to develop multiplatform applications for arm-linux, arm-wince and possibly a port to x86 platforms, so at now I would to create simplest "hello world" with lazarus targeted on arm-linux/wince. For example, here ( http://talk.maemo.org/showthread.php?t=1846 ) there is a comment that explicate what I would to do (ok, it is only fpc oriented, but step two will be fpc+lazarus). In that thread is mentioned the tutorial I linked at first (
http://wiki.lazarus.freepascal.org/Setup_Cross_Compile_For_ARM )...

So, in first place I would make able fpc to cross compile for generic arm-linux and than "enable" Lazarus to do that.

As you can see, I'm not expert about all this things... for this reason I need step by step help in everything, even worse english is not my main language so I have some difficulties to understand perfectly all suggestions, the sparse informations and outdated guides in the web about cross compiling with lazarus/fpc.

Thank you.

Hi :)
I don't know if it will help, but back in 2007, I started a website:

http://fpc4gp2x.eonclash.com/

which allows one to make programs for an arm-linux handheld, the gp2x.

It has a freepascal cross-compiler that works under Windows 32, and generates arm-linux binaries :)

I know it is over 2 years old now, but perhaps it may still help?

cheers,
Paul

2009/12/7 Paul Nicholls :

Hi!
Thanks for reply!

I read the site, but I found a pre-compiled "FPC_win32_arm-linux" with all cross compiling files already builded (e.g. ppccrossarm.exe).

I need to know how to build my own "FPC_win32_arm-linux" starting from a generic/latest "fpcscr.zip" :)

e.g. CodeTyphon make it from latest svn/cvs snapshot of fpc and lazarus, but at the linking time, after compile, there is an error with link of X11 (-lX11). I tried to see what their program do to build fpc/lazarus arm-linux compatible, but I can't understand all. CodeTyphon have some hidden procedure (not visible script), so I can view only output commands...

Please, help me to make a generic script/tutorial to make fpc/lazarus arm-linux "compatible"!

Thank you!

I have this script to compile FPC from svn:

make crossinstall CPU_TARGET=arm OS_TARGET=linux

there are two folders with toolchain

Ok, probably this is the mistake. Thank you!
I was trying to compile from fpcscr (current dir) where I had not root access (I didn't know that it save file in current dir, I thought that it save in destination dir).
In few hours I think I can try, I had to reinstall my ubuntu 9.10 (fortunately it is a vm) and recompile fpc/lazarus from sources...

Hi again,

I re-compiled all (fpc+lazarus+binutils) on a fresh Ubuntu 9.10 x86 VM (virtualbox) and it seems to be ok.

Lazarus compile x86 code.

Now I'm trying again to make fpc/lazarus compatible with arm, but there are other problems.

I compiled the ppcrossarm:
~$ ~/lazarus/fpc/2.5.1/lib/fpc/2.5.1/ppcrossarm -iV 2.5.1

But when I try to compile a simple "TestARM.pas" program:

~/TestARM$ cat TestARM.pas
program hello;
 begin
   writeln ('Hello!');
 end.

I get this error:

~/TestARM$ ~/lazarus/fpc/2.5.1/lib/fpc/2.5.1/ppcrossarm -XParm-linux- TestARM.pas

Some suggestions?

Furthermore, if I set in Lazarus->Project->Compiler Options->Code:

There is this error:

"The project uses target OS=Error: ppcarm can't be executed, error message: Failed to execute "ppcarm", error code: 127. The system.ppu for this target was not found in the FPC binary directories. Make sure fpc is installed correctly for this target and fpc.cfg contains the right directories."

Hi all,
I'm writing a tutorial to cross compile for arm-linux, but there are some problems yet.
Here first revision:
http://forum.lazarus.freepascal.org/index.php/topic,8084.0.html

I don't know if all steps are right, infact FPC compile simplest code and my arm-linux device runs that, but I can't get Lazarus cross compiling... it returns: "/tmp/project1.lpr(1,1) Fatal: Can't find unit system used by Project1"

For command line FPC compiling I tried more complex program, with other units than default, but it give error. I tried the example program linked here:

I have all libraries incompatible... how make it compatible? (or where to find these...)

Thanks

This puts all ppu files to /usr/lib/fpc/2.5.1/units/arm-linux/. Normally every project/package has it's own directory for its ppu files. But now you have mixed them all up, which means all documentation don't work for you. You can proceed if you know what you are doing, or remove all files in this directory and restart.

You forgot to install the X11 libraries for arm.
LCL applications also needs the gtk2 libraries.

The gtk2 must be written small (LCL_PLATFORM=gtk2).

You should have done in the first place instead of the above with the -FU option.
But since you have already compiled the lcl and put its ppu files into a global directory you are out of luck.

I don't know.

2009/12/12 Mattias Gaertner :

Ummm... sincerely I don't know very well what I'm doing... there are very few examples in web, so I tried some things that I find in similar threads.
However ok, I'm going to remove and re-unpack all sources, but what is the command I need to do to preserve "every project/package in its own directory for its ppu files"?

You forgot to install the X11 libraries for arm. LCL applications also needs the gtk2 libraries.

Umm... I can't find in synaptic/repository/other (maybe, do I need to compile by fpc?)... now I'm trying to grab these libs from my arm device.

So, in a new/clear installation, after I have FPC that cross compile for arm-linux and before to compile first time Lazarus from sources, what do I need to do?

What I understand:

1) Compile Lazarus for the host.
2) /lazarus$ make lcl LCL_PLATFORM=gtk2 PP=ppcarm CPU_TARGET=arm OS_TARGET=linux
3) /lazarus/packager/registration/$ make PP=ppcarm CPU_TARGET=arm OS_TARGET=linux
4) ?

Thank you!

Kjow

PS I'm sorry if I don't understand, but I find just few examples in how to use these commands...

The linux arm support for FPC is quite new.

However ok, I'm going to remove and re-unpack all sources, but what is the command I need to do to preserve "every project/package in its own directory for its ppu files"?

This is automatically done by the IDE.
Just start the IDE in a terminal, compile a package normally and see what it does.

I wrote a few hints here:
http://wiki.lazarus.freepascal.org/Cross_compiling#Cross_compiling_the_LCL

No. gtk2 and X11 are written in C.
So if there are no cross compiled packages for arm, you may have to cross compile them yourself. See the gtk website of how to do that.

Lazarus is the IDE, LCL and a bunch of components. You only need the LCL and a few components.

2) /lazarus$ make lcl LCL_PLATFORM=gtk2 PP=ppcarm CPU_TARGET=arm OS_TARGET=linux 3) /lazarus/packager/registration/$ make PP=ppcarm CPU_TARGET=arm OS_TARGET=linux

Yes.
You can do that via the IDE.

4) ?

Install the cross compiled libraries for arm. I never did that so I can't give any hints here.

PS I'm sorry if I don't understand, but I find just few examples in how to use these commands...

Cross compiling is an advanced topic.

2009/12/12 Mattias Gaertner :

Thank you very much, Mattias. You are very gentle.

Well, FPC compile right for my device:

Nokia-N900-42-11:/home/opt/KjowProject/Test01# ./test DATE 2009/12/12
FPCTARGET arm
FPCTARGETCPU arm
FPCTARGETOS Linux
FPCVERSION 2.5.1
Nokia-N900-42-11:/home/opt/KjowProject/Test01#

But Lazarus Projects still have some problems. I'm restarted from a new fresh ubuntu installation, so I reinstalled fpc, binutils (both from latest source snaphot) and enabled fpc to cross compile for arm-linux. All ok.
Then compiled Lazarus with classic: ~/lazarus$ make clean all All ok.
Then I followed you wiki-instructions and compiled LCL+Package registration from Lazarus IDE. All OK.

I tried to build a simple form, but I got this error:

Probably you have somewhere an old ppu from your former experiments in the search path. Add options -vu -vt to find out where it is.

Open the IDE compiler options. You can see that the IDE passes some -Fu and other options. Simply copy those options if you want to compile at the command line.

No, I don't have any old ppu. I restarted from a fresh ubuntu installation (it is a virtual machine, so I just overwrite the hard disk image).
But I don't know where to put -vu -vt options in Lazarus IDE... I tried in Project->Compiler Options->Compilation->Show Options and added to the end.

See below for:
1) Lazarus IDE compiling errors
2) command line compiling errors

Do you mean these Project->Compiler Options->Compilation->Show Options ?

/home/kjow/lazarus/fpc/binutils/ld: skipping incompatible /usr/lib/libX11.so when searching for -lX11
/home/kjow/lazarus/fpc/binutils/ld: skipping incompatible /usr/lib/libX11.a when searching for -lX11
/home/kjow/lazarus/fpc/binutils/ld: cannot find -lX11 LAzARM.lpr(22) Error: Error while linking
LAzARM.lpr(22) Fatal: There were 1 errors compiling module, stopping

So I need to find arm-linux compiled libraries.

I grabbed someone like:

libX11.so.6
libX11.so.6.2.0

and I put these files here: /home/kjow/lazarus/fpc/libcross

Now, how can I tell to linker to search in this path?

An other question; compiling from terminal the same project above, I still have this problem:

~/dev/TestARM/LazARM$ fpc -Tlinux -Parm LAzARM.lpr Free Pascal Compiler version 2.5.1 [2009/12/12] for arm Copyright (c) 1993-2009 by Florian Klaempfl
Target OS: Linux for ARM
Compiling LAzARM.lpr
Fatal: Can't find unit Interfaces used by LAzARM
Fatal: Compilation aborted
Error: /usr/local/bin/ppcarm returned an error exitcode (normal if you did not specify a source file to be compiled)

Thanks!
