Overview

These instructions cover cross compiling to Linux on ARM. See arm-wince for instructions on cross-compiling to Windows CE on ARM.

Cross compile with FPC for ARM (e.g. Zaurus)

  • First, setup a cross compilation environment; you can get more information about this here [1], here [2] and here [3].
  • Install the lastest native FPC from sourceforge
  • get an ARM FPC snapshot from the downloads page of FPC Qt Binding for Zaurus
  • Download it to somedir. The name of the tar file may be different of course:
cd somedir
tar zxvf arm-linux-fpc.i386-linux-20050217.tar.gz
  • you will find a 'lib/fpc/1.9.7/units/arm-linux/...' dir. The version may be '1.9.8' or higher.
  • create FPC library directory structure for FPC in a lib directory on your system
  • most systems use '/usr/local/lib', some use '/usr'
mkdir -p /usr/local/lib/fpc/1.9.7/units
cp -fr lib/fpc/1.9.7/units/arm-linux /usr/local/lib/fpc/1.9.7/units/
  • copy the FPC cross compiler to its default place
cp lib/fpc/1.9.7/ppcarm /usr/local/lib/fpc/1.9.7
  • set a soft link to it in a bin dir in your path
  • most distributions use '/usr/local/bin', some '/usr/bin'
ln -sf /usr/local/lib/fpc/1.9.7/ppcarm /usr/local/bin/ppcarm
  • verify you can call ppcarm; it should return something like '1.9.7' and not 'command not found'
ppcarm -iV

cd somedir
tar zxvf binutils.tar.gz
  • copy the 2 programs in the tar to a bin dir in your path
cp arm-linux-* /usr/local/bin
  • create a 'Hello World' program and compile it
echo "program hello; begin writeln('Hello World'); end." > hello.pas
ppcarm -XParm-linux- hello.pas
  • output should be something like this:
# ppcarm -XParm-linux- hello.pas
Free Pascal Compiler version 1.9.7 [2005/02/17] for arm

Assembling hello
Linking hello
1 Lines compiled, 0.2 sec
  • Copy it to the home directory of the user 'zaurus' on your zaurus device.
  • With an SSH setup this could be as simple as:
scp hello zaurus:/home/zaurus
  • Install terminal program on your Zaurus. For a Zaurus SL6000: see manual on CD.
  • Run the terminal program. On a SL6000 the console will default to user 'zaurus' in its home dir /home/zaurus
  • Run the program
./hello
  • Output should be something like:
Hello World
