| # Android CMake toolchain file, for use with the Android NDK r5-r10d |
| # Requires cmake 2.6.3 or newer (2.8.9 or newer is recommended). |
| # See home page: https://github.com/taka-no-me/android-cmake |
| # |
| # Usage Linux: |
| # $ export ANDROID_NDK=/absolute/path/to/the/android-ndk |
| # $ mkdir build && cd build |
| # $ cmake -DCMAKE_TOOLCHAIN_FILE=path/to/the/android.toolchain.cmake .. |
| # $ make -j8 |
| # |
| # Usage Windows: |
| # You need native port of make to build your project. |
| # Android NDK r7 (and newer) already has make.exe on board. |
| # For older NDK you have to install it separately. |
| # For example, this one: http://gnuwin32.sourceforge.net/packages/make.htm |
| # |
| # $ SET ANDROID_NDK=C:\absolute\path\to\the\android-ndk |
| # $ mkdir build && cd build |
| # $ cmake.exe -G"MinGW Makefiles" |
| # -DCMAKE_TOOLCHAIN_FILE=path\to\the\android.toolchain.cmake |
| # -DCMAKE_MAKE_PROGRAM="%ANDROID_NDK%\prebuilt\windows\bin\make.exe" .. |
| # $ cmake.exe --build . |
| # |
| # |
| # Options (can be set as cmake parameters: -D<option_name>=<value>): |
| # ANDROID_NDK=/opt/android-ndk - path to the NDK root. |
| # Can be set as environment variable. Can be set only at first cmake run. |
| # |
| # ANDROID_ABI=armeabi-v7a - specifies the target Application Binary |
| # Interface (ABI). This option nearly matches to the APP_ABI variable |
| # used by ndk-build tool from Android NDK. |
| # |
| # Possible targets are: |
| # "armeabi" - ARMv5TE based CPU with software floating point operations |
| # "armeabi-v7a" - ARMv7 based devices with hardware FPU instructions |
| # this ABI target is used by default |
| # "armeabi-v7a with NEON" - same as armeabi-v7a, but |
| # sets NEON as floating-point unit |
| # "armeabi-v7a with VFPV3" - same as armeabi-v7a, but |
| # sets VFPV3 as floating-point unit (has 32 registers instead of 16) |
| # "armeabi-v6 with VFP" - tuned for ARMv6 processors having VFP |
| # "x86" - IA-32 instruction set |
| # "mips" - MIPS32 instruction set |
| # |
| # 64-bit ABIs for NDK r10 and newer: |
| # "arm64-v8a" - ARMv8 AArch64 instruction set |
| # "x86_64" - Intel64 instruction set (r1) |
| # "mips64" - MIPS64 instruction set (r6) |
| # |
| # ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for. |
| # Option is read-only when standalone toolchain is used. |
| # Note: building for "android-L" requires explicit configuration. |
| # |
| # ANDROID_TOOLCHAIN_NAME=arm-linux-androideabi-4.9 - the name of compiler |
| # toolchain to be used. The list of possible values depends on the NDK |
| # version. For NDK r10c the possible values are: |
| # |
| # * aarch64-linux-android-4.9 |
| # * aarch64-linux-android-clang3.4 |
| # * aarch64-linux-android-clang3.5 |
| # * arm-linux-androideabi-4.6 |
| # * arm-linux-androideabi-4.8 |
| # * arm-linux-androideabi-4.9 (default) |
| # * arm-linux-androideabi-clang3.4 |
| # * arm-linux-androideabi-clang3.5 |
| # * mips64el-linux-android-4.9 |
| # * mips64el-linux-android-clang3.4 |
| # * mips64el-linux-android-clang3.5 |
| # * mipsel-linux-android-4.6 |
| # * mipsel-linux-android-4.8 |
| # * mipsel-linux-android-4.9 |
| # * mipsel-linux-android-clang3.4 |
| # * mipsel-linux-android-clang3.5 |
| # * x86-4.6 |
| # * x86-4.8 |
| # * x86-4.9 |
| # * x86-clang3.4 |
| # * x86-clang3.5 |
| # * x86_64-4.9 |
| # * x86_64-clang3.4 |
| # * x86_64-clang3.5 |
| # |
| # ANDROID_FORCE_ARM_BUILD=OFF - set ON to generate 32-bit ARM instructions |
| # instead of Thumb. Is not available for "armeabi-v6 with VFP" |
| # (is forced to be ON) ABI. |
| # |
| # ANDROID_NO_UNDEFINED=ON - set ON to show all undefined symbols as linker |
| # errors even if they are not used. |
| # |
| # ANDROID_SO_UNDEFINED=OFF - set ON to allow undefined symbols in shared |
| # libraries. Automatically turned for NDK r5x and r6x due to GLESv2 |
| # problems. |
| # |
| # ANDROID_STL=gnustl_static - specify the runtime to use. |
| # |
| # Possible values are: |
| # none -> Do not configure the runtime. |
| # system -> Use the default minimal system C++ runtime library. |
| # Implies -fno-rtti -fno-exceptions. |
| # Is not available for standalone toolchain. |
| # system_re -> Use the default minimal system C++ runtime library. |
| # Implies -frtti -fexceptions. |
| # Is not available for standalone toolchain. |
| # gabi++_static -> Use the GAbi++ runtime as a static library. |
| # Implies -frtti -fno-exceptions. |
| # Available for NDK r7 and newer. |
| # Is not available for standalone toolchain. |
| # gabi++_shared -> Use the GAbi++ runtime as a shared library. |
| # Implies -frtti -fno-exceptions. |
| # Available for NDK r7 and newer. |
| # Is not available for standalone toolchain. |
| # stlport_static -> Use the STLport runtime as a static library. |
| # Implies -fno-rtti -fno-exceptions for NDK before r7. |
| # Implies -frtti -fno-exceptions for NDK r7 and newer. |
| # Is not available for standalone toolchain. |
| # stlport_shared -> Use the STLport runtime as a shared library. |
| # Implies -fno-rtti -fno-exceptions for NDK before r7. |
| # Implies -frtti -fno-exceptions for NDK r7 and newer. |
| # Is not available for standalone toolchain. |
| # gnustl_static -> Use the GNU STL as a static library. |
| # Implies -frtti -fexceptions. |
| # gnustl_shared -> Use the GNU STL as a shared library. |
| # Implies -frtti -fno-exceptions. |
| # Available for NDK r7b and newer. |
| # Silently degrades to gnustl_static if not available. |
| # |
| # ANDROID_STL_FORCE_FEATURES=ON - turn rtti and exceptions support based on |
| # chosen runtime. If disabled, then the user is responsible for settings |
| # these options. |
| # |
| # What?: |
| # android-cmake toolchain searches for NDK/toolchain in the following order: |
| # ANDROID_NDK - cmake parameter |
| # ANDROID_NDK - environment variable |
| # ANDROID_STANDALONE_TOOLCHAIN - cmake parameter |
| # ANDROID_STANDALONE_TOOLCHAIN - environment variable |
| # ANDROID_NDK - default locations |
| # ANDROID_STANDALONE_TOOLCHAIN - default locations |
| # |
| # Make sure to do the following in your scripts: |
| # SET( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${my_cxx_flags}" ) |
| # SET( CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${my_cxx_flags}" ) |
| # The flags will be prepopulated with critical flags, so don't loose them. |
| # Also be aware that toolchain also sets configuration-specific compiler |
| # flags and linker flags. |
| # |
| # ANDROID and BUILD_ANDROID will be set to true, you may test any of these |
| # variables to make necessary Android-specific configuration changes. |
| # |
| # Also ARMEABI or ARMEABI_V7A or X86 or MIPS or ARM64_V8A or X86_64 or MIPS64 |
| # will be set true, mutually exclusive. NEON option will be set true |
| # if VFP is set to NEON. |
