| PROGRAM_PARAMETERS="[<toolchain-name>+]" |
| PROGRAM_DESCRIPTION="\ |
| This program is used to rebuild one or more NDK cross-toolchains from scratch. |
| To use it, you will first need to call download-toolchain-sources.sh to download |
| the toolchain sources, then pass the corresponding directory with the |
| --toolchain-src-dir=<path> option. |
| |
| If you don't pass any parameter, the script will rebuild all NDK toolchains |
| for the current host system [$HOST_TAG]. You can otherwise give a list of |
| toolchains among the following names: |
| |
| arm-linux-androideabi-4.4.3 |
| arm-linux-androideabi-4.6 |
| x64-4.4.3 |
| x86-4.6 |
| mipsel-linux-android-4.4.3 |
| mipsel-linux-android-4.6 |
| |
| By default, the script rebuilds the toolchain(s) for you host system [$HOST_TAG], |
| but you can use --systems=<tag1>,<tag2>,.. to ask binaries that can run on |
| several distinct systems. Each <tag> value in the list can be one of the |
| following: |
| |
| linux-x86 |
| linux-x86_64 |
| windows |
| windows-x86 (equivalent to 'windows') |
| windows-x86_64 |
| darwin-x86 |
| darwin-x86_64 |
| |
| For example, here's how to rebuild the ARM toolchains on Linux |
| for four different systems: |
| |
| $PROGNAME --toolchain-src-dir=/path/to/toolchain/src \ |
| --systems=linux-x86,linux-x86_64,windows,windows-x86_64 \ |
| arm-linux-androideabi-4.4.3 \ |
| arm-linux-androideabi-4.6 |
| |
| You can build Windows binaries on Linux if you have a Windows-targetting |
| cross-toolchain installed and in your path. Note that the script named |
| 'build-mingw64-toolchain.sh' can be used to rebuild such a toolchain |
| (x86_64-w64-mingw32) from sources if you don't have one available. |
| |
| Building the toolchains directly under Cygwin/MSys has not be tested and |
| is not recommended (it will be *extremely* slow, if it ever works). |
| |
| On Darwin, the script will try to probe any compatibility SDK installed |
| on your development machine and will use the first it finds among a list |
| of well-known names. You can however force a specific usage with the |
| --darwin-sdk-version=<version> name, where <version> can be one of 10.4, 10.5, |
| 10.6, 10.7, etc. |
| |
| The generated binaries should run on 10.5 or higher. You can force a |
| different compatibility minimum with --darwin-min-version. |
| |
| If you want to build Darwin binaries on a non-Darwin machine, you will |
| have to define DARWIN_TOOLCHAIN / DARWIN_SYSROOT in your environment first |
| (note: this feature is highly experimental). |
| |
| The script is sufficiently clever to minimize all build steps, especially |
| if you try to build several toolchains for several distinct host systems. Note |
| however that generating a canadian-cross toolchain (e.g. building on Linux a |
| Windows toolchain that targets Android ARM binaries) will force the generation |
| of a host toolchain as well, in case it is not listed in your --systems list. |
| This is required to generate proper target GCC libraries. |
| |
| The toolchain binaries are installed under \$NDK_DIR/toolchains by default, |
| but you can use --ndk-dir=<path> to specify a different NDK installation path. |
| The script will try to build the Gold linker for host/target combination that |
| are well supported (Gold doesn't build / is buggy for some of them). However, |
| the BFD linker is still the default used by the generated toolchain. You can |
| change this behaviour with two options: |
| |
| --default-ld=<name> Changes the default toolchain linker. |
| <name> can be one of 'default', 'bfd' and 'gold'. |
| |
| For now, 'default' is an alias for 'bfd', but we plan |
| to map it to 'gold' for some combos in the future, once |
| we're confident it works reliably |
| |
| --force-gold-build Force the build of the Gold linker, even if it is known |
| to fail or generate a buggy linker. Only use this for |
| experimentation (e.g. with your own patched toolchain |
| sources). |

| |
| # Important note: When identifying a build or host system, there is |
| # a difference between 'NDK system tags' and "GNU configuration triplet'. |
| # |
| # A "system tag" is specific to the NDK and identifies a given host |
| # system for the toolchain binaries, valid values: |
| # |
| # linux-x86 |
| # linux-x86_64 |
| # windows (historical alias to windows-x86) |
| # windows-x86 |
| # windows-x86_64 |
| # darwin-x86 |
| # darwin-x86_64 |
| # |
| # A GNU configuration triplet identifies a system too, but it used by |
| # configure scripts, not the NDK. They vary a lot too and some of the |
| # scripts are *very* picky about the exact values being used. |
| # |
| # Typical values that are known to work properly: |
| # |
| # i686-linux-gnu (Linux x86 system, with GNU libc) |
| # x86_64-linux-gnu (Same, with x86_64 CPU) |
| # i586-mingw32msvc (Windows 32-bits, MSVCRT.DLL) |
| # i586-pc-mingw32msvc (same) |
| # i686-w64-mingw32 (same, slightly different sources) |
| # x86_64-w64-mingw32 (Windows 64-bits, MSVCRT.DLL) |
| # i686-apple-darwin (OS X / Darwin, x86 CPU) |
| # x86_64-apple-darwin (OS X / Darwin, x86_64 CPU) |
| # |
| # A cross-toolchain will typically use the GNU configuration triplet as |
| # a prefix for all its binaries, but not always. For example, the 'mingw32' |
| # package on Ubuntu provides a Windows cross-toolchain that uses the |
| # i586-mingw32msvc prefix, but if you try to use it as a configuration |
| # triplet when configuring binutils-2.21, the build will fail. You need to |
| # pass i586-pc-mingw32msvc instead (binutils-2.19 accepts both). |
| # |
| # Another issue is that some toolchains need to use additional compiler |
| # flags to deal with backwards-compatibility SDKs (Darwin) or 32/64 bit |
| # code generation. Note all build scripts accept the same mix of |
| # '--with-cflags=...' or 'export CFLAGS' configuration, which makes |
| # things pretty difficult to manage. |
| # |
| # To work-around these issues, the script will generate "wrapper toolchains" |
| # with the prefix that the configure scripts expects. I.e. small scripts that |
| # redirect to the correct toolchain, eventually adding hidden extra compiler |
| # flags. This seems to completely get rid of the problems described above. |
