To use it, you will need a working set of toolchain sources, like 29 those downloaded with download-toolchain-sources.sh, then pass the 30 corresponding directory with the --toolchain-src-dir=<path> option. 31 32 By default, the script rebuilds GDB for you host system [$HOST_TAG], 33 but you can use --systems=<tag1>,<tag2>,.. to ask binaries that can run on 34 several distinct systems. Each <tag> value in the list can be one of the 35 following: 36 37 linux-x86 38 linux-x86_64 39 windows 40 windows-x86 (equivalent to 'windows') 41 windows-x86_64 42 darwin-x86 43 darwin-x86_64 44 45 For example, here's how to rebuild the ARM toolchains on Linux 46 for four different systems: 47 48 $PROGNAME --toolchain-src-dir=/path/to/toolchain/src \ 49 --systems=linux-x86,linux-x86_64,windows,windows-x86_64 \ 50 --arch=arm" 51 52 TOOLCHAIN_SRC_DIR= 53 register_var_option "--toolchain-src-dir=<path>" TOOLCHAIN_SRC_DIR "Select toolchain source directory" 54 55 GDB_VERSION="6.6 7.3.x" 56 register_var_option "--gdb-version=<version>" GDB_VERSION "Select GDB version(s)." 57 58 BUILD_DIR= 59 register_var_option "--build-dir=<path>" BUILD_DIR "Build GDB into directory" 60 61 PYTHON_VERSION= 62 register_var_option "--python-version=<version>" PYTHON_VERSION "Python version." 63 64 PYTHON_BUILD_DIR= 65 register_var_option "--python-build-dir=<path>" PYTHON_BUILD_DIR "Python build directory." 66 67 NDK_DIR=$ANDROID_NDK_ROOT 68 register_var_option "--ndk-dir=<path>" NDK_DIR "Select NDK install directory." 69 70 PACKAGE_DIR= 71 register_var_option "--package-dir=<path>" PACKAGE_DIR "Package prebuilt tarballs into directory." 72 73 ARCHS=$DEFAULT_ARCHS 74 register_var_option "--arch=<list>" ARCHS "Build GDB client for these CPU architectures." 75 76 bh_register_options 77 78 register_jobs_option 79 80 extract_parameters "$@" 81 82 if [ -n "$PARAMETERS" ]; then 83 panic "This script doesn't take parameters, only options.
