This was relatively clear for a PC lazarus  to  winCE arm
download
lazarus-0.9.26.2-fpc-2.2.2-win32.exe
Lazarus-0.9.26-fpc-2.2.2-cross-arm-wince-win32.exe
write hello world for 386 PC and see it work
Project >compile options>path  LCL widget type ...wince(beta)
Project > compile options>code target os...WinCe
Project > compile options>code target cpu family ...arm
Project > compile options>code target processor... default
Project > compile options>Linking select only  .... strip symbols
Run build all
move project executable project1.exe to ce device and run  It worked!

Very confused for linux arm
For a pC running unbuntu and lazarus 0.9.26
 LCL widget type is dfault(gtk) target os and cpu are defaults
hello world compiles and runs on the PC
now for the confusion
the arm device is s2c2440  the gui is qt embedded 2.2.0
selecting
Project >compile options>path  LCL widget type ...qt(beta)
Project > compile options>code target os...Linux
Project > compile options>code target cpu family ...arm
Project > compile options>code target processor... default
Project > compile options>Linking select only  .... strip symbols
results in
system.ppu was not found in the FPC directories.
Make sure fpc is installed correctly and the fpc.cfg points to the
right directory

I downloaded fpc-2.2.2.arm-linux.tar but its very confusing as to how
to install this
correctly and even if installed I don't know if it will allow a
lazurus IDE cross compile as occurs with Wince. I am a newbie but was
very encouraged when the wince install didn't take me into the weeds.
I'm in the weeds with lazarus PC ubuntu and a cross compile to linux
arm qt gui

Quotesystem.ppu was not found in the FPC directories. You need to
rebuild the rtl for arm linux (or download one).
QuoteI downloaded fpc-2.2.2.arm-linux.tar but its very confusing as to
how to install this correctlyExtract and move the units directory into
your FPC's unit directory (so you should have i386-linux and arm-linux
under it).
Quoteand even if installed I don't know if it will allow a lazurus IDE
cross compile as occurs with WincePerhaps not. You need to build the
arm cross compiler (if you have ppcarm along with ppc386, then you
already have it). Search wiki or marco's buildfaq to find out how.

Yes, the linux arm installation is very confusing and there isn't
2.2.4 arm pakage version in the site.
In the Lazarus snapshot site there are all for Windows but not for
Linux
On Windows all works well and all is simple to do.
I think that che fpc I386 and arm version must be equals but on the
site there is only 2.3.1 arm fpc.

You are able to make it work?


Sorry for my bad english.
