The HAIKU_* tools 22 variables will be set accordingly. 23 --build-cross-tools-gcc4 <arch> <build tools dir> 24 Like "--build-cross-tools" just that gcc 4 will 25 be used for cross-compilation. Note, that the 26 resulting Haiku installation built with gcc 4 27 will not be binary compatible with BeOS R5. 28 <arch> specifies the target architecture, either 29 "x86" or "ppc". 30 --alternative-gcc-output-dir <dir> 31 Build a Haiku installation that supports running 32 executables built with a gcc version incompatible 33 with the primary gcc (e.g. gcc 2 executables under 34 a gcc 4 Haiku or vice versa). <dir> specifies the 35 output directory of the other gcc. The directory 36 must already be fully configured. 37 --cross-tools-prefix <prefix> 38 Assume cross compilation. <prefix> should be a 39 path to the directory where the cross 40 compilation tools are located, plus the platform 41 prefix, e.g. "/path/to/tools/i586-pc-haiku-". 42 This overrides the HAIKU_* tool variables. 43 --distro-compatibility <level> 44 The distribution's level of compatibility with 45 the official Haiku distribution. The generated 46 files will contain the respective trademarks 47 accordingly. 48 official -- the official Haiku distribution. 49 compatible -- a Haiku Compatible (tm) distro. 50 default -- any other distro (default value). 51 --help Prints out this help. 52 --include-gpl-addons Include GPL licensed add-ons. 53 --include-3rdparty Include 3rdparty/ in the build system. 54 --enable-multiuser Enable experimental multiuser support. 55 --target=TARGET Select build target platform. [default=${target}] 56 valid targets=r5,bone,dano,haiku 57 --use-gcc-pipe Build with GCC option -pipe. Speeds up the build 58 process, but uses more memory. 59 --use-32bit Use -m32 flag on 64bit host gcc compiler. 60 --use-xattr Use Linux xattr support for BeOS attribute 61 emulation. Warning: Make sure your file system 62 supports sufficient attribute sizes (4 KB per 63 file for all attributes won't suffice). 64 65environment variables: 66 HAIKU_AR The static library archiver.
