* fMyLatency (stupid name) had an arbitrary bogus value,
it should be more like the scheduling latency, if anything. * fBufferMap contained uint32 values, instead of simply the BBuffer pointers. * fBufferMap was initialized in a very complicated way, simply use the BBuffer pointer returned from fBuffers->AddBuffer(). * Removed methods which were only implemented because of a Codewarrior compiler bug. * Renamed fTargetBufferIndex to fLastBufferIndex, since it's the index of the last used BBuffer from fBufferMap, which needs to be recycled when the next buffer is received. * SetOutputBuffersFor() never worked (making the producer use the consumer buffer group), since it was passed the never initialized fDestination. Use fIn.destination. * But using our own buffer group did not yet work, since apparently the BBuffer pointers cannot be compared like the code did (no idea if it ever worked on BeOS). Compare the ID()s instead, which makes it finally work to save an unnecessary memcpy(). Interestingly, one can call Recycle() on the "wrong" BBuffer pointer and buffers still get recycled correctly. * Refactored methods _UnsetTargetBuffer() and _HandleBuffer(). * Maintain the performance start time, may come in handy later. * Changed code that checks lateness or earliness of buffers. In case a buffer is early, simply wait. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38661 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 "generated/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 --------------------- 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. This creates a bootable 'haiku-cd.iso' in your 'generated/' folder: jam -q haiku-cd 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-cd.iso Here x,y,z is the device number as found with cdrecord -scanbus, it can also be a device path on Linux. 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.
