1) Extract the toolchain to /

	# cd /
	# tar -jxvf /path/to/arm-linux-toolchain-3.3.2.tar.bz2
        
this will install everything in /usr/local/arm/3.3.2.

You should then

	# ln -s /usr/local/arm/3.3.2/arm-linux /usr/local/arm-linux
        
So that:

/usr/local/arm-linux points to the arm "image" (arm-linux binaries); and

/usr/local/arm/3.3.2 points to the cross-compiling tools (host binaries)


2) Supplemental precompiled libraries/headers

	# cd /usr/local/arm-linux
        # tar -jxvf /path/to/arm-linux-suppimage.tar.bz2


3) Syncing with PDA

You probably don't want to copy everything in /usr/local/arm-linux to /lib or
/usr/lib on you PDA. You certainly don't need the includes/headers. Also, to
save space you should make sure everything is stripped as much as possible. You
can't strip libraries completely (or they won't link), but you can turf any
debugging information with

	$ arm-linux-strip -d library.so.0.0.0.0

Some have already been stripped and reside in /usr/local/arm-linux/lib/stripped
These can be copied to /lib on the PDA, if/when you need them.

Copy them over however you like. Familiar runs sshd, so scp is prolly the thing.


4) How to cross compile

With GNU Autoconf it's easy:

	$ export PATH="/usr/local/arm/3.3.2/bin:$PATH"
        $ ./configure --host=arm-linux --prefix=/usr/local/arm-linux --libdir=/usr/local/arm-linux/lib
        $ make
        # make install 		#optional

then sync.
