even if "kernel_startup" was "true". Page faults are now no longer allowed during kernel startup (and could be easily avoided). The only situation where we accept page faults with interrupts turned off now is during a kernel debugger session. Added a command debug_debugger_running() to test for that situation. kernel_debugger() no longer sets kernel_startup while it's running; there should be no situation when this could be helpful. Interrupts are no longer enabled when a page fault happens in the kernel debugger. This potentially fixes all sorts of problems, and not only in the kernel debugger, it could also have affected SMP (will test later). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14045 a95241bf-73f2-0310-859d-f6bbb57e9c96
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. Configuring -------- 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 or makehdimage (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 -------- The preferred method to build Haiku (currently only possible on a BeOS machine) is this: $ makehdimage /Haiku Where "/Haiku" is the mounted BFS partition where you want to install Haiku on. This can be any BFS partition with enough space available. Use DriveSetup to initialize a partition to BFS. If the parameter is omitted, makehdimage currently creates a 60 MB Haiku image in this directory that you can use for Bochs, Qemu and other emulators to boot. To build the whole source tree for your selected target platform (to use the apps, drivers, add-ons, etc.) you can simply invoke Jam: $ jam Or to build only a specific app/driver/etc. include it as an argument: $ jam Pulse NOTE: If you have checked out the latest SVN revision, it is not unlikely that some parts of the tree won't build. Running ------- Generally there are two ways of running Haiku. On real hardware using a partition and on emulated hardware using an emulator like Bochs. 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 a "haiku.image" using makehdimage without arguments. How to setup this image depends on your emulater. A tutorial for Bochs on BeOS is below. 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.
