Title: Cross Compile with FPC for ARM

New		Line
1	+	## Overview
2	+
3	+	These instructions cover cross compiling to Linux on ARM. See [[arm-wince]] for instructions on cross-compiling to Windows CE on ARM.
4	+
5	+	## Cross compile with FPC for ARM (e.g. Zaurus)
6	+
7	+	- First, setup a cross compilation environment; you can get more information about this here [1](http://www.cartel-securite.fr/pbiondi/zaurus/crosscompile.html), here [2](http://www.nautilus6.org/operation/doc/wide-memo-nautilus6-zaurus-ccenv-setup-00.txt) and here [3](http://projects.buici.com/arm/cross/).
8	+	- Install the lastest native FPC [from sourceforge](http://sourceforge.net/project/showfiles.php?group_id=89339)
9	+	- get an ARM FPC snapshot from the downloads page of [FPC Qt Binding for Zaurus](http://users.pandora.be/Jan.Van.hijfte/qtforfpc/qtedemo.html)
10	+	- Download it to somedir. The name of the tar file may be different of course:
11	+
12	+	``` bash
13	+	cd somedir
14	+	tar zxvf arm-linux-fpc.i386-linux-20050217.tar.gz
15	+	```
16	+
17	+	- you will find a 'lib/fpc/1.9.7/units/arm-linux/...' dir. The version may be '1.9.8' or higher.
18	+	- create FPC library directory structure for FPC in a lib directory on your system
19	+	- most systems use '/usr/local/lib', some use '/usr'
20	+
21	+	``` bash
22	+	mkdir -p /usr/local/lib/fpc/1.9.7/units
23	+	cp -fr lib/fpc/1.9.7/units/arm-linux /usr/local/lib/fpc/1.9.7/units/
24	+	```
25	+
26	+	- copy the FPC cross compiler to its default place
27	+
28	+	``` bash
29	+	cp lib/fpc/1.9.7/ppcarm /usr/local/lib/fpc/1.9.7
30	+	```
31	+
32	+	- set a soft link to it in a bin dir in your path
33	+	- most distributions use '/usr/local/bin', some '/usr/bin'
34	+
35	+	``` bash
36	+	ln -sf /usr/local/lib/fpc/1.9.7/ppcarm /usr/local/bin/ppcarm
37	+	```
38	+
39	+	- verify you can call ppcarm; it should return something like '1.9.7' and not 'command not found'
40	+
41	+	``` bash
42	+	ppcarm -iV
43	+	```
44	+
45	+	- download [FPC 1.9.x ARM binutils](ftp://ftp.freepascal.org/pub/fpc/snapshot/v19/arm-linux/binutils.tar.gz) to somedir
46	+
47	+	``` bash
48	+	cd somedir
49	+	tar zxvf binutils.tar.gz
50	+	```
51	+
52	+	- copy the 2 programs in the tar to a bin dir in your path
53	+
54	+	``` bash
55	+	cp arm-linux-* /usr/local/bin
56	+	```
57	+
58	+	- create a 'Hello World' program and compile it
59	+
60	+	``` bash
61	+	echo "program hello; begin writeln('Hello World'); end." > hello.pas
62	+	ppcarm -XParm-linux- hello.pas
63	+	```
64	+
65	+	- output should be something like this:
66	+
67	+	# ppcarm -XParm-linux- hello.pas

75	+
76	+	- Copy it to the home directory of the user 'zaurus' on your zaurus device.
77	+	- With an SSH setup this could be as simple as:
78	+
79	+	``` bash
80	+	scp hello zaurus:/home/zaurus
81	+	```
82	+
83	+	- Install terminal program on your Zaurus. For a Zaurus SL6000: see manual on CD.
84	+	- Run the terminal program. On a SL6000 the console will default to user 'zaurus' in its home dir /home/zaurus
85	+	- Run the program
86	+
87	+	``` bash
88	+	./hello
89	+	```
90	+
91	+	- Output should be something like:
92	+
93	+	Hello World
