Building on a non-BeOS platform
===============================

We currently support these non-BeOS platforms:
 * Linux
 * FreeBSD

To build Haiku on a non-BeOS platform you must first check out and build the
cross-compiler. The easiest method for doing so is to check it out in a
directory just below that of the Haiku root. Navigate to the parent directory
of Haiku and use a command such as:

  svn checkout svn://svn.berlios.de/haiku/buildtools/trunk buildtools

You should now have a 'buildtools' folder that contains folders named
'binutils' and 'gcc' among others.


Building Jam
============

Change to the buildtools folder and we will start to build 'jam' which is a
requirement for building Haiku. Run the following commands to generate and
install the tool:

  cd  buildtools/jam  
  make
  sudo ./jam0 install


Building binutils
=================

The binutils used by Haiku will be automatically generated according to the
initial configuration of the Haiku source and placed in the
'generated/cross-tools' directory of Haiku. Before generating the tools you
must consider the version required, there are essentially two choices:

  * 2.95: Creates BeOS compatible binaries
  * 4.x: Incompatible with BeOS, but theoretically more efficient binaries

Unless there is a pressing need, choose 2.95 as the latter option can cause
frequent build issues. The commands for configuration are,

GCC 2.95
--------

  cd haiku 
  ./configure --build-cross-tools ../buildtools/

GCC 4.x
-------

  cd haiku
  ./configure --build-cross-tools-gcc4 x86 ../buildtools/

The process can take quite some time, but when it finishes you are ready to
compile your first Haiku image.

Instructions on how to build Haiku can be found in the 'ReadMe' document.
