Setting Up
----------
The build system uses Jam/MR (http://www.perforce.com/jam/jam.html).
A BeOS executable of Jam 2.5 is available at:
http://haiku-os.org/downloads.php?mode=download&id=10&mirror=0
Unzip the executable and copy it to /boot/home/config/bin.
The Jam source code is also included in the source tree. You can as well cd
into "src/tools/jam" and run "make" to obtain an executable.
To build Haiku you also need Oliver Tappe's GCC 2.95.3. You can get it at BeBits:
http://www.bebits.com/app/4011
Older versions of GCC 2.95.3 will likely not work.
If you intend to build Haiku from a supported build platform other than BeOS,
e.g. GNU/Linux, you need to build a jam executable yourself (don't use the
one coming with your distribution). cd into the "src/tools/jam" subdirectory
of the Haiku tree and type "make" (or "gmake"). The generated jam executable
will be found in a platform specific subdirectory, e.g. "bin.linuxx86/".
The easiest way to use it, is to copy it to a place in your PATH. Furthermore
you need to build the tools for cross compilation (binutils and gcc). Fear not,
the configure script will help you with that one; see below.
Configuring
-----------
Under BeOS:
Open a Terminal and change to your Haiku trunk folder. To configure the build you
can run configure like this:
$ ./configure --target=TARGET
Where "TARGET" is the target platform for the build. Valid targets are "r5",
"bone", "dano" and "haiku". If you omit the target it defaults to "haiku". To
configure for ZETA use the "dano" target.
The configure script generates a file named "BuildConfig" in the "build"
directory. As long as configure is not modified (!), there is no need to call it
again. That is for re-building you only need to invoke jam (see below).
If you don't update the source tree very frequently, you may want to execute
configure after each update just to be on the safe side.
Under Linux or another supported build platform:
You don't need to supply the "--target" option to configure, since the only
supported target is the default "haiku" anyway. But you have to tell, what
cross compilation tools to use. The tools installed in the system won't work
for compiling Haiku itself (they will be used for building some build tools,
though). The easiest way is to instruct configure to build those tools from the
sources. Supposing you have checked out the buildutils module from the Haiku
SVN repository alongside the Haiku source tree, you can do that via:
$ ./configure --build-cross-tools ../buildtools
One of the last output lines should tell you that the tools have been built
successfully.
Note, that the old gcc 2.95.3 will be used for building Haiku, required for
binary compatibility with BeOS R5. If you're not interested in binary
compatibility (or want to build for the PowerPC architecture), you can instead
use:
$ ./configure --build-cross-tools-gcc4 <arch> ../buildtools
Replace "<arch>" with either "x86" or "ppc", depending on which of the two
architectures you want to build for.
[At the moment (2005-12-06) the build for PowerPC, or at least the resulting
Haiku does not work.]
Building
--------
Haiku can be built in either of two ways, as disk image file (e.g. for use with
emulators) or as installation in a directory.
Image File:
$ jam -q haiku-image
Generates an image file named "haiku.image" in your output directory (usually
"generated/"). This method works for all supported build platforms.
Directory Installation:
$ HAIKU_INSTALL_DIR=/Haiku jam -q install-haiku
Installs all Haiku components into the directory "/Haiku". If that directory
is the root of a mounted BFS partition, you'll have a Haiku partition afterwards.
To create a partition in the first place use DriveSetup and initialize it to BFS.
Note, that installing Haiku in a directory only works as expected under BeOS.
Building Components:
If you don't want to build the complete Haiku, but only a certain app/driver/etc.
you can specify it as argument to jam, e.g.:
$ jam Pulse
Running
-------
Generally there are two ways of running Haiku. On real hardware using a partition
and on emulated hardware using an emulator like Bochs or QEmu.
1. On Real Hardware
If you have installed Haiku to it's own partition you can include this partition
in your bootmanager and try to boot Haiku like any other OS you have installed.
To include a new partition in the BeOS bootmanager run this in a Terminal:
$ bootman
And follow the steps of the installer.
2. On Emulated Hardware
For emulated hardware you should build disk image (see above). How to setup this
image depends on your emulater. A tutorial for Bochs on BeOS is below. If you
use QEmu, you can usually just provide the path to the image as command line
argument to the "qemu" executable.
Bochs
-----
Version 2.2 of Bochs for BeOS (BeBochs) can be downloaded from BeBits:
http://www.bebits.com/app/3324
The package installs to: /boot/apps/BeBochs2.2
You have to set up a configuration for Bochs. You should edit the ".bochsrc" to
include the following:
ata0-master: type=disk, path="/path/to/haiku.image", cylinders=122, heads=16, spt=63
boot: disk
Now you can start Bochs:
$ cd /boot/apps/BeBochs2.2
$ ./bochs
Answer with RETURN and with some patience you will see Haiku booting.
If booting into the graphical evironment fails you can try to hit "space" at the
very beginning of the boot process. The Haiku bootloader should then come up and
you can select some safe mode options.
Docbook documentation
---------------------
Requirements :
- Docbook XML DTD (http://www.oasis-open.org/docbook/xml/4.2/docbook-xml-4.2.zip)
