that can be used by file systems. * Changed the way the file cache works: instead of reading/writing to the underlying device directly, it can now be used for any data source, ie. also network file systems. * As a result, the former pages_io() moved to the VFS layer, and can now be called by a file system via {read|write}_file_io_vec_pages() (naming suggestions are always welcomed :-)). It now gets an FD, and uses that to communicate with the device (via its fs_{read|write}_pages() hooks). * The file_cache_{read|write}() functions must now be called without holding an I/O relevant file system lock. That allows the file cache to prepare the pages without colliding with the page writer, IOW the "mayBlock" flag can go into the attic again (yay!). * This also results in a much better performance when the system does I/O and is low on memory, as the page writer can now finally write back some pages, and that even without maxing out the CPU :) * The API changes put slightly more burden on the fs_{read|write}_pages() hooks, but in combination with the file_map it's still pretty straight forward. It just will have to dispatch the call to the underlying device directly, usually it will just call its fs_{read|write}_pages() hooks via the above mentioned calls. * Ported BFS and FAT to the new API, the latter has not been tested, though. * Also ported the API changes to the fs_shell. I also completely removed its file cache level page handling - the downside is that device access is no longer cached (ie. depends on the host OS now), the upside is that the code is greatly simplified. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22886 a95241bf-73f2-0310-859d-f6bbb57e9c96 |

Building on BeOS ================ For building on BeOS you need the development tools from: http://haiku-os.org/downloads Please always use the most recent versions. They are required to build Haiku. Building on a non-BeOS platform =============================== Please read the file 'ReadMe.cross-compile' before continuing. It describes how to build the cross-compilation tools and configure the build system for building Haiku. After following the instructions you can directly continue with the section Building. Configuring on 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 that the compiled code should run on: * haiku (default) * r5 * bone * dano (also for Zeta) 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. 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 This generates an image file named 'haiku.image' in your output directory under 'generated/'. VMware Image File ----------------- jam -q haiku-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-haiku 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 BeOS, but it is not yet supported under Linux and other non-BeOS platforms. 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 Alternatively, you can 'cd' to the directory of the component you want to build and run 'jam' from there. You can also force rebuilding of a component by using the "-a" parameter: jam -a 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. 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 BeOS bootmanager run this in a Terminal: bootman 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 ===================== Our documentation can be found in 'src/documentation/'. You can build it by running 'jam' in that folder. The results will be stored in the 'generated/' folder.
