Sorry for sending already again an email.
I invested another 20 minutes to the mini-howto.

It is now fully generic but should be tested with other platforms.

Marcel: tell me if it's ok or you'd like other changes...

regards
Marco

This document shows how to cross-compile bluez for another processor.

date/version: 01 Feb. 2005, v0.2
author:       Marco Trudel <mtrudel@gmx.ch>

If you need help, please use the bluez-user list.
If you have improvements or hints, do not hesitate to contact the autor.

This howto has been testet for:
	i686 -> arm

------------------------------------------------------------

Ensure that the crosscompile binaries are in $PATH.
For example, do: export PATH="$PATH:/thePathToYourCrossCompiler/bin"

Please note: The term DESTDIR will be used in the following commands.
             This is the directory where bluez will be installed to.
	     Replace it, for example, with /opt/bluez or /tmp/bluez.

########## 1. compile bluez-libs ##########
- extract bluez-libs and change into the directory
- configure the makefiles for cross-compiling:
        ./configure --build=i686-pc-linux-gnu  \
                    --host=arm-linux           \
                    --prefix=DESTDIR           \
                    [--sysconfdir=DESTDIR/etc]

- Explanation of the switches:
        --build        The build platform (as example a i686).
	--host         The target platform (as example arm-linux).
	               Please change it to match your target-system.
	--prefix       Where bluez will be installed to.
	--sysconfdir   Where bluez will expect etc.
	               You can remove this switch if /etc is ok for you.

- Check the output. Some interesting lines:
        checking for arm-linux-gcc... arm-linux-gcc
        checking whether the C compiler works... yes
        checking whether we are cross compiling... yes

- run "make", "make install"

########## 2. compile bluez-utils ##########
- extract bluez-utils and change into the directory
- configure the makefiles for cross-compiling. run:
        ./configure --build=i686-pc-linux-gnu  \
                    --host=arm-linux           \
                    --prefix=DESTDIR           \
                    [--sysconfdir=DESTDIR/etc  \]
                    LDFLAGS=-LDESTDIR/lib

- LDFLAGS is where the bluez lib will be searched for.
(Please note that -L is needed. For example LDFLAGS=-L/opt/bluez/lib)

- run "make" and "make install"


######### 3. final steps, tests ##########
Please note: This mini-howto assumes you have a bluetooth enabled kernel.
If you haven't already, install it now.

Depending on your setup, you might be interested in every kb
of diskspace to save. With -s stripping and removing of unnecessary
files, it's possible to save ~350kb...

copy DESTDIR to your target platform.

on your target platform:
- add "DESTDIR/lib" to /etc/ld.so.conf and, run "ldconfig"
- run "./hcid -n" in DESTDIR/sbin
Check the output.
If everything works well, abort hcid and start it withhout "-n".

- "DESTDIR/bin/hcitool dev" should show you your devices
- "DESTDIR/bin/hcitool scan" perform an inquiry scan
