before (although there should be much less lock contention) * with this change, there is quite a bit of cleanup, text drawing is now about 20% faster than before the original changes to font caching, mostly due to turning off the kerning feature, which at the moment gives absolutely no benefit. The correct way of doing it might be to use kerning depending on the provided glyph spacing mode * removed fPenLocation from Painter, the usage should be more correct now, since it is now consistently applied before the coordinate transformation from view to screen (also for DrawShape() now, before any view scaling and origin offset) * Painter no longer has it's own instance of a ServerFont, instead it uses its AGGTextRenderer instance, which was per Painter again after the last change, and not global anymore, made _UpdateFont() useless * When using GlyphLayoutEngine, it supports a second pass with the same FontCacheEntry through the introduction of a FontCacheReference. This speeds up DrawString a little, since it needs to calculate the bounding box for the string, and then draw the string in a second pass. This is now done with only one FontCacheEntry lookup * I also tried to optimize the on-the-fly conversion of UTF8->CharCode away, since it was done four times per DrawString, but surprisingly, it proofed to be a slight slowdown. * introduced a shortcut in DrawingEngine::DrawString() which avoids calculating the bounding box, we are now a tiny bit faster to figure out that we don't need to draw any string than Dano In the test environment (drawing to offscreen bitmap and blitting to screen eventually), text rendering is now about 3.7 times _faster_ than Dano text rendering (directly to screen), for untransformed text. Unfortunately I cannot test on the same machine in accelerant using version of the test environment. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21822 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.
