* When the device watcher/control thread encounteres an error when read()ing or ioctl()ing the device, don't just quit the thread and leave a stale device add-on hanging there, but instead trigger _RemoveDevice() to exit this cleanly. This also takes care of calling _RemoveDevice() only from one thread. However, it adds a race condition should a mouse or keyboard be unplugged and plugged at the same time. I need to think about how to fix that cleanly, although the situation may be theoretical only... This fix seems to fix another problem with hot-plugging USB mice, before this change, the first mouse entry in /dev/input/mouse/usb/ was never gone and I got two entries after unplugging and replugging. * When using BObjectList configured to own the entries - don't delete the entries! Also don't call RemoveItem() before still using the item. Took me all day to find this one, because the code looked so... correct. :-} * In _AddDevice() call _RemoveDevice() just for the sake of it. It is really important that no device with the same name is published twice. The PS/2 driver behaves strange in that it publishes device more than once, if I understand correctly, until it decides that there is no device. * Only StartMonitoringDevice() /after/ having performed the initial device scan! Or else we may get ourselves confused. I don't know if this was an actual problem, but the code was like that before and it seems saner to me. Seeing there is no locking in the device add-on itself, we may already enter the code from the node monitor thread. This should fix #2894. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28321 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. Bootable CD-ROM Image --------------------- * UNSUPPORTED yet * This _requires_ having the mkisofs tool installed. On Debian GNU/Linux for example you can install it with: apt-get install mkisofs On BeOS you can get it from http://bebits.com/app/3964 along with cdrecord. Creating a bootable CD requires burning 2 tracks on a single CD. The first track is an El-Torito bootable ISO file-system containing a boot floppy image, and is created with: jam -q haiku-boot-cd This generates an image file named 'haiku-boot-cd.iso' in your output directory under 'generated/'. The second track is the raw BFS image 'haiku.image' in 'generated/' created with: jam -q haiku-image Under Unix/Linux, and BeOS you can use cdrecord to create a CD with: cdrecord dev=x,y,z -v -eject -dao -data generated/haiku-boot-cd.iso generated/haiku.image Here x,y,z is the device number as found with cdrecord -scanbus, it can also be a device path on Linux. Windows users will find '3rdparty/nero/haiku-cd.cue' useful. Since the CD has two tracks it is not easy to test it from an emulator. Instead it is simpler to use the 'haiku.image' as CD image and the floppy image 'haiku-boot-floppy.image' to boot from it. For Qemu: qemu -cdrom generated/haiku.image -fda generated/haiku-boot-floppy.image -boot a 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.
