Hi All, we thought we would look at compiling the Arduino source. This webpage explains the process: https://code.google.com/p/arduino/wiki/BuildingArduino

Here is a Youtube video.

However, the process is not easy to follow. What is a Java JDK (is this eclipse?) and where is it found. What is meant by "Of the packages" and where are the defaults found? How do you change the JAVA_HOME directory? Has anyone managed to compile the Arduino source and how hard was it? Any easy to follow steps would be much appreciated.

On Windows, you'll need Cygwin, a Java JDK, and ant.

Cygwin is downloadable from http://www.cygwin.com/ or specifically: http://www.cygwin.com/setup.exe

Of the packages, begin with the defaults, and add:

git - used for version control
make, gcc-mingw, and g++ - used to build arduino.exe (this will also pull in gcc-core)
perl - use this version, activestate or other distros have trouble
unzip, zip - for dealing with archives
Included in the defaults, but make sure:

coreutils (or textutils), gzip, tar
Not required but useful:

openssh - command line ssh client
nano - handy/simple text editor
And be sure to leave the option selected for 'unix line endings'

Download and install ant. Add the apache-ant-xxx\bin directory to your path.

Download and install a Java JDK and point the JAVA_HOME environment variable to its root directory. An error message that reads "Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar" means you need to set JAVA_HOME to your JDK (not JRE) installation.
