To use it, you will need a working set of toolchain sources, like 34 those downloaded with download-toolchain-sources.sh, then pass the 35 corresponding directory with the --toolchain-src-dir=<path> option. 36 37 By default, the script rebuilds Python for you host system [$HOST_TAG], 38 but you can use --systems=<tag1>,<tag2>,.. to ask binaries that can run on 39 several distinct systems. Each <tag> value in the list can be one of the 40 following: 41 42 linux-x86 43 linux-x86_64 44 windows 45 windows-x86 (equivalent to 'windows') 46 windows-x86_64 47 darwin-x86 48 darwin-x86_64 49 50 For example, here's how to rebuild Python 2.7.5 on Linux 51 for six different systems: 52 53 $PROGNAME --build-dir=/path/to/toolchain/src \n \ 54 --python-version=2.7.5 \n \ 55 --systems=linux-x86,linux-x86_64,windows,windows-x86_64,darwin-x86,darwin-x86_64" 56 57 TOOLCHAIN_SRC_DIR= 58 register_var_option "--toolchain-src-dir=<path>" TOOLCHAIN_SRC_DIR "Select toolchain source directory" 59 60 PYTHON_VERSION=$DEFAULT_PYTHON_VERSION 61 register_var_option "--python-version=<version>" PYTHON_VERSION "Select Python version." 62 63 NDK_DIR=$ANDROID_NDK_ROOT 64 register_var_option "--ndk-dir=<path>" NDK_DIR "Select NDK install directory." 65 66 PACKAGE_DIR= 67 register_var_option "--package-dir=<path>" PACKAGE_DIR "Package prebuilt tarballs into directory." 68 69 BUILD_DIR= 70 register_var_option "--build-dir=<path>" BUILD_DIR "Build Python into directory" 71 72 bh_register_options 73 register_try64_option 74 register_canadian_option 75 register_jobs_option 76 77 extract_parameters "$@" 78 79 if [ -n "$PARAMETERS" ]; then 80 panic "This script doesn't take parameters, only options.
