Building Haiku

This is a overview into the process of building HAIKU from source. An online version is available at https://haiku-os.org/guides/building/.

Official releases of Haiku are at https://haiku-os.org/get-haiku. The (unstable) nightly builds are available at https://download.haiku-os.org/.

We currently support the following platforms:

  • Haiku
  • Linux
  • FreeBSD
  • Mac OS X

Required Software

Tools provided within Haiku's repositories:

  • jam (Jam 2.5-haiku-20111222)
  • Haiku's cross-compiler (needed only for non-Haiku platforms)

The tools to compile Haiku will vary, depending on the platform that you are using to build Haiku. When building from Haiku, all of the necessary development tools are included in official releases (e.g. R1 alpha4) and in the nightly builds.

  • git
  • ssh (for developers with commit access)
  • gcc/g++ and binutils (as, ld, etc., required by GCC)
  • (GNU) make
  • bison (2.4 or better)
  • flex and lex (usually a mini shell script invoking flex)
  • makeinfo (part of texinfo, only needed for building GCC 4)
  • autoheader (part of autoconf, needed for building GCC)
  • automake
  • gawk
  • nasm
  • wget
  • [un]zip
  • cdrtools (not genisoimage!)
  • case-sensitive file system

Whether they are installed can be tested by running them in a shell with the --version parameter.

The following libraries (and their respective headers) are required:

  • curl
  • zlib

Haiku for ARM

If you want to compile Haiku for ARM, you will also need:

On Mac OS X

Disk Utility can create a case-sensitive disk image of at least 3 GiB in size. The following ports need to be installed:

  • expat
  • gawk
  • gettext
  • libiconv
  • gnuregex
  • gsed
  • cdrtools
  • nasm
  • wget
  • less
  • mpfr
  • gmp
  • libmpc

More information about individual distributions of Linux and BSD can be found at https://haiku-os.org/guides/building/pre-reqs.

Downloading Haiku's sources

There are two parts to Haiku's sources — the code for Haiku itself and a set of build tools for compiling Haiku on an operating system other than Haiku. The buildtools are needed only for non-Haiku platforms.

Anonymous checkout:

git clone https://git.haiku-os.org/haiku
git clone https://git.haiku-os.org/buildtools

(You can also use the git:// protocol, but it is not secure).

If you have commit access:

git clone ssh://git.haiku-os.org/haiku
git clone ssh://git.haiku-os.org/buildtools

Building Jam

(This step applies only to non-Haiku platforms.)

Change to the buildtools folder and run the following commands to generate and install jam:

cd buildtools/jam
make
sudo ./jam0 install

Or, if you don't want to install jam systemwide:

./jam0 -sBINDIR=$HOME/bin install

Configuring the build

The configure script generates a file named BuildConfig in the generated/build directory. As long as configure is not modified (!) and the cross-compilation tools have not been updated, there is no need to call it again. For rebuilding, 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.

Depending on your goal, there are several different ways to configure Haiku. You can either call configure from within your Haiku trunk folder. That will prepare a folder named 'generated', which will contain the compiled objects. Another option is to manually created one or more generated.* folders and run configure from within them. For example, imagine the following directory setup:

buildtools-trunk/
haiku-trunk/
haiku-trunk/generated.x86gcc2

Configure a GCC 2.95 Hybrid, from a non-Haiku platform

cd haiku-trunk/generated.x86gcc2
../configure --use-xattr-ref \
	--build-cross-tools x86_gcc2 ../../buildtools/ \
	--build-cross-tools x86

Configure a GCC 2.95 Hybrid, from Haiku

cd haiku-trunk/generated.x86gcc2
../configure --target-arch x86_gcc2 --target-arch x86

Additional information about GCC Hybrids can be found on the website, https://haiku-os.org/guides/building/gcc-hybrid.

Configure options

The various runtime options for configure are documented in its onscreen help

./configure --help

Building via Jam

Haiku can be built in either of two ways, as disk image file (e.g. for use with emulators, to be written directly to a usb stick, burned as a compact disc) or as installation in a directory.

Running Jam

There are various ways in which you can run jam:

  • If you have a single generated folder, you can run 'jam' from the top level of Haiku's trunk.
  • If you have one or more generated folders, (e.g. generated.x86gcc2), you can cd into that directory and run jam.
  • In either case, you can cd into a certain folder in the source tree (e.g. src/apps/debugger) and run jam -sHAIKU_OUTPUT_DIR=

Be sure to read build/jam/UserBuildConfig.ReadMe and UserBuildConfig.sample, as they contain information on customizing your build of Haiku.

Building a Haiku anyboot file

jam -q @anyboot-image

This generates an image file named haiku-anyboot.image in your output directory under generated/.

Building a VMware image file

jam -q @vmware-image

This generates an image file named haiku.vmdk in your output directory under generated/.

Directory Installation

HAIKU_INSTALL_DIR=/Haiku jam -q @install

Installs all Haiku components into the volume mounted at "/Haiku" and automatically marks it as bootable. 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 Haiku, but it is not yet supported under Linux and other non-Haiku platforms.

Building individual 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 -q Debugger

Alternatively, you can cd to the directory of the component you want to build and run jam from there. NOTE: if your generated directory is named something other than generated/, you will need to tell jam where it is:

jam -q -sHAIKU_OUTPUT_DIR=<path to generated folder>

You can also force the rebuild of a component by using the -a parameter:

jam -qa Debugger

Running

Generally there are two ways of running Haiku: on real hardware using a partition, and on emulated hardware using an emulator (like VirtualBox, or QEMU).

On Real Hardware

If you have installed Haiku to its 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 Haiku bootmanager, start the BootManager configurator by running:

BootManager

On Emulated Hardware

For emulated hardware you should build disk image (see above). How to set up this image depends on your emulator. If you use QEMU, you can usually just provide the path to the image as command line argument to the qemu executable.
