AVR Toolchain for Arduino
This is the AVR Toolchain used in the Arduino IDE.
As soon as Atmel ships a newer toolchain, we pull the source code, patch it with some user contributed patches and deliver it with the Arduino IDE. Therefore, the resulting binaries may differ significantly from Atmel's. And you should start blaming us if things are not working as expected :)
build.conf file, currently the only thing worth changing is
AVR_VERSION on the first line to match whatever the latest version is.
At time of writing, the latest toolchain available is based on Atmel 3.5.4 version. It contains:
Setup has been done on partially set up development machines. If, trying to compile on your machine, you find any package missing from the following list, please open an issue at once! We all can't afford wasting time on setup :)
To just build, after getting the requirements...
./tools.bash ./binutils.build.bash ./gcc.build.bash ./libc.build.bash ./gdb.build.bash
after a successful compile the binaries etc will be found in
To package, after getting the requirements...
sudo apt-get install build-essential gperf bison subversion texinfo zip automake flex libtinfo-dev pkg-config
Mac OSX requirements
You need to install MacPorts: https://www.macports.org/install.php. Once done, open a terminal and type:
sudo port selfupdate sudo port upgrade outdated sudo port install wget +universal sudo port install automake +universal sudo port install autoconf +universal sudo port install gpatch +universal sudo port install gsed +universal
You need to install Cygwin: http://www.cygwin.com/. Once you have run
setup-x86.exe, use the
Search text field to filter and select for installation the following packages:
- texinfo (must be at version 4.13 since 5+ won't work)
A note on texinfo: due to dependencies, each time you update/modify your cygwin installation (for example: you install an additional package), texinfo will be upgraded to version 5+, while you need version 4+! Easy solution: as soon as you've installed the additional package, re-run cygwin setup, search texinfo, triple click on "Keep" until you read version 4, then click next.
You also need to install MinGW: http://www.mingw.org/. Once you have run mingw-get-setup.exe, select and install (clicking on "Installation" -> "Apply changes") the following packages:
Build process ported from Debian. Most patches come from Atmel. Thank you guys for your awesome work.
