[Tutorial] Cross Compile for arm-linux (Finally it works!)

[Marcovaldo]

Add -XParm-linux-

That worked!

Thank you very much for your fast help!!!

Kind greetings from Vienna,

Hello fpc-Arm-Linux-guys,

is there anyone out there, who tried do run the crosscompiler-script in the recent days? It seems that some links in Kjooows script are broken, especially the file

ftp.freepascal.org/pub/fpc/dist/2.5.1/i386-linux/rpm/fpc-2.5.1-1.i686.rpm

is not available. I will try to do the job manually with the related fpc.zip.

Some other issues concerning this theme:

Now i did the job manually along the wiki. Even here i detected some error:

Compiling the fpc2.5.1 from sources needs Version > FPC2.4.0, indicated 2.2.0 gives the message: use fpc version > 2.4.0.

Furthermore crosscompiling fpc2.5.1 for arm stopps with an error.

BTW: Trying CodeTyphons solution results in some errors, too and does not produce a usable cross-compiler for arm-linux.

In respect to some other problems, i.e the unreliable compatibility to the libraries of the linux-targets i wonder, wether it would be better to port our (30.000 line) project to such an unbeloved target as wince.

Compiling the fpc2.5.1 from sources needs Version > FPC2.4.0, indicated 2.2.0 gives the message: use fpc version > 2.4.0.

It's mentioned in the docs that you should always use the previous stable version to compile the compiler from sources. So for (cross-) compiling 2.5.1 svn you should use fpc 2.4.2.

Furthermore crosscompiling fpc2.5.1 for arm stopps with an error.

Yes, I had the same problem about a week ago cross-compiling for arm-wince. It does happen occasionnally that it gets broken but is generally fixed fairly quickly.

Gr.
Dirk.

Hello,

I've set up my crosscompiling environment on ubuntu. I've used the script lazarus_first_time.
I can successfully compile a helloworld.pas program. I've copied the binary file to the following ARM platform: http://opengear.com/product-acm5000.html
But i can't run it. the error message is segmentation fault.

After that, I've installed the CDK from Opengear
pls. see: http://community.pachube.com/node/690

I'm able to compile and link a c program. I can run the c program on the Target Device.
The Dev Kit from Opengear installs a different version of binutils
(Linker Assembler ...) but these tools are incompatible with FPC. (FPC can not use them, if I compile helloworld.pas)

The Dev Kit from Opengear can not work with the FPC Binutils.

So I'm in a trap. How to solve that problem ?

Thanks,
SF

Hi

I try to use the script lazarus_first_time on a new (virtual) machine.

The directory  /home/$NAME/fpc_tools/binutils/binutils-2.20.1/  is renamed to /home/$NAME/fpc_tools/ and later there is a cd and commands into the old directory name. This can't work...

I do not know what is right...

Code: [Select]

[b]mv /home/$NAME/fpc_tools/binutils/binutils-2.20.1/ /home/$NAME/fpc_tools/[/b]

cd /home/$NAME/
#swap --> Please, use one of these combinations: "FPC 2.4.2 + Lazarus 0.9.30 -> fixes" OR "FPC 2.5.1 + Lazarus 0.9.31 -> trunk"
svn co http://svn.freepascal.org/svn/lazarus/trunk lazarus
#svn co http://svn.freepascal.org/svn/lazarus/branches/fixes_0_9_30/ lazarus
cd /home/$NAME/lazarus/
svn up

cd /home/$NAME/lazarus/components/
svn co https://glscene.svn.sourceforge.net/svnroot/glscene/trunk glscene

echo "Install & Configure Binutils"
[b]cd /home/$NAME/fpc_tools/binutils-2.20.1[/b]
./configure --target=arm-linux --disable-werror
make
sudo make install
By the way, it would be useful to update 0.9.30 to 0.9.30.2 since the last one is the last stable release.

I have made small improvements in the script :

1) to avoid changes in 3 different places
2) to include a debug mode to be able to see error messages

If you are interested it is attached.

I made two scripts that download svn sources and zip needed to build and configure your Ubuntu (x86) box with Lazarus AND FPC (both are enabled to compile for i386-linux and cross compile for arm-linux).

Do not run these scripts, they complete messed-up my Lazarus and FPC configuration and it took me half a day to clean up and re-install everything.

[tintinux]

Do not run these scripts

True, I had the same issue and I had to reinstall Lazarus from scratch.

When trying such things, it is advisable to use a VirtualBox as I did the second time (and found reported errors).

I got it finnaly i was able to compile a simple form for ARM Youpi and thanks for the help.
After pass 30 min to rename a buch of so.0.2 -> .so everything is ok now

My main application is a shop barcode scanner using overo air (wireless & bluetooth)
This application need to connect to a mysql5 database on my locale network so i'm using a TMySQL50Connection , ect  this application only have a few button and this compoment. when i try to compile it i got this

registersqldb.pas(45,3) Fatal: Can't find unit propedits used by registersqldb

Can someone give me a tpis on how using mysql database and arm ?

Many Thanks again for the help

I'm glad to know that it works now.

The component that you use for mysql, works well con i386-linux compiling?
If yes, try to recompile LCL and Package registration:
http://wiki.lazarus.freepascal.org/Setup_Cross_Compile_For_ARM#Configure_Lazarus_for_cross_Compile
(paragraph "Configure Lazarus for cross Compile" only)

hi !I got it finnaly and  thanks for the Setup_Cross_Compile_For_ARM.
 ;)My main application need The component ¨Lnet ¨,i try to recompile LCL and Package registration:Configure Lazarus for cross Compile,but ¨/home/user/lazarus/fpc/inet0.6.6/lib/lcommon.pp(537) Error: Assembler /home/user/lazarus/fpc/binutils/as not found, switching to external assembling¨,
plc tall me how can i use the  component ¨Lnet ¨

Error: Assembler /home/user/lazarus/fpc/binutils/as

Do you have cross arm binutils installed? If yes, how are they named? If it's something like i386-linux-<name>, probably you need to adjust the fpc.cfg to have -XP$FPCTARGET- so the compiler would look for, for example the assembler, as i386-linux-as instead of just plain as.

Hello, I'm having the same problem, follow the step by step of http://wiki.lazarus.freepascal.org/Setup_Cross_Compile_For_ARM.

I'm trying to build lazarus and I get the error: /home/mint/lazarus/packager/registration/lazaruspackageintf.pas(104) Error: Assembler arm-linuxas not found, switching to external assembling

Could anyone help me?

[Diego]

Fix it, adding -XParm-linux- in lazarus, following Tools -> Configure Build Lazarus -> Options. The last dash (-) is very important, without it I believe the fpc concatenates the assembly (arm-linuxas), which should be arm-linux-as.

Now I am getting the below error, someone could explain why? I'm using 64bit linux.

If you see my reply to kc87654321, you won't experience this.

Check your binutils. If it's already 64-bit, I don't think it accepts --64 parameter. Not sure though, better consult binutils documentation.

Hello Leledumbo, thanks for replying.

I have found no way to correct this error, so I installed a new linux 32bit in a VM, but after arriving in step "Configure Lazarus for cross Compile" tutorial http://wiki.lazarus.freepascal.org/Setup_Cross_Compile_For_ARM still get the error, but now with '--32'

Erro:

I believe that the problem is not on the platform. : /

The strange thing is that at no time do not add the option '--32' and do not know where and at what time this command is inserted.

Would you assist me?
