4	jasmin	1	== AVR32 Toolchain Builder ==
		2
		3	This is a early implementation of a Makefile for an AVR32 toolchain
		4	builder for Mac OS X & Linux, and it has not been extensively tested.
		5	That said the patches are taken directly from Atmel, and basic testing
		6	is done with some more complicated builds (i.e.:
		7	link:http://eluaproject.net[eLua] in float and integer mode) to ensure
		8	that that at least these work after toolchain modifications.
		9
		10	Note: If you have previously built a toolchain of another version, out
		11	of the same builder directory, make sure to do the following first
		12	before building with newer sources:
		13
		14	----
		15	make clean
		16	----
		17
		18	=== Requirements (OS X) ===
		19
		20	You will need to have GCC, make and binutils on your machine to
		21	compile all of this. You can get all of these on Mac OS X, by just
		22	installing the Apple
		23	link:http://developer.apple.com/technologies/tools/[Developer Tools].
		24	You should be able to download free versions of 3.x from the ADC
		25	website, install from the OS X install disc that came with your
		26	machine, or download XCode 4 from the App Store (now free again for
		27	all registered users).
		28
		29	You will also need gmp, mpfr and mpc first. I recommend installing
		30	these from link:https://github.com/mxcl/homebrew[homebrew] for now.
		31	I'll add these to the Makefile once I have a consistent configuration
		32	that can be used for both Linux & OS X.
		33
		34	With homebrew you can install those dependencies like this:
		35	----
		36	brew install mpfr gmp libmpc texinfo
		37	----
		38
		39	If you would like to build dfu-programmer, also install libusb:
		40
		41	----
		42	brew install libusb-compat
		43	----
		44
		45
		46	=== Requirements (Ubuntu) ===
		47
		48	These instructions should now also work on Ubuntu Linux, provided the
		49	following packages have been installed prior to attempting the build:
		50
		51	----
		52	sudo apt-get install curl flex bison libgmp3-dev libmpfr-dev autoconf build-essential libncurses5-dev libmpc-dev texinfo
		53	----
		54
		55	If you would like to build dfu-programmer, also install libusb:
		56
		57	----
		58	sudo apt-get install libusb-dev
		59	----
		60
		61	=== Main Build Instructions ===
		62
		63	Next build the toolchain:
		64
		65	----
		66	make install-cross
		67	----
		68
		69	You should be able to also specify a specific install/prefix location
		70	by building using the following type of invokation:
		71
		72	----
		73	PREFIX=$HOME/avr32-tools make install-cross
		74	----
		75
		76	If you do this, make sure you have permissions to create a directory
		77	at this location and/or to create directories within this location if
		78	the directory already exists.
		79
		80
		81	NOTE: If you're running Mac OS X Lion or XCode 4.1 you may find that
		82	you're unable to bootstrap GCC. To work around this until the issue
		83	is fixed in Apple's distribution of llvm-gcc, use the following
		84	command instead of the above to build.
		85
		86	----
		87	CC=gcc-4.2 make install-cross
		88	----
		89
		90
		91
		92	This should build the compiler, newlib, gdb, etc.. and install them all
		93	into a directory called arm-cs-tools in your home directory. If you
		94	want to install to another location, feel free to change the export
		95	lines and to adjust the definitions at the top of the Makefile.
		96
		97	Keep in mind that the Makefile does install at the end of each build.
		98
		99	Once you’re done, the makefile should notify you of the install
		100	location, which will be based on the git revision if you cloned the
		101	repository or the current date if you grabbed a tarball and/or you
		102	don't have the git binary. The message should look like the following:
		103
		104	----
		105	====== INSTALLATION NOTE ======
		106	Your tools have now been installed at the following prefix:
		107	/Users/jsnyder/avr32-tools-bd2485b
		108
		109	Please be sure to add something similar to the following to your .bash_profile, .zshrc, etc:
		110	export PATH=/Users/jsnyder/avr32-tools-bd2485b/bin:$PATH
		111	----
		112
		113	If it uses the date instead the the git short revision will bve
		114	replaced with a date number like: 20110726.
		115
		116	If you also would like dfu-programmer installed intalled (make sure
		117	you have previously installed libusb as described in requirements):
		118
		119	----
		120	make install-dfu
		121	----
		122
		123	=== Special Thanks ===
		124
		125	Special thanks to Rob Emanuele for the basis of this Makefile:
