3 | 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 | |||
