# Android CMake toolchain file, for use with the Android NDK r5-r8 |
|
# Requires cmake 2.6.3 or newer (2.8.5 or newer is recommended). |
|
# See home page: https://github.com/taka-no-me/android-cmake |
|
# |
|
# The file is mantained by the OpenCV project. The latest version can be get at |
|
# http://code.opencv.org/projects/opencv/repository/revisions/master/changes/android/android.toolchain.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 Linux (using standalone toolchain): |
|
# $ export ANDROID_STANDALONE_TOOLCHAIN=/absolute/path/to/android-toolchain |
|
# $ 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 (or 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_STANDALONE_TOOLCHAIN=/opt/android-toolchain - path to the |
|
# standalone toolchain. This option is not used if full NDK is found |
|
# (ignored if ANDROID_NDK is set). |
|
# 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" - matches to the NDK ABI with the same name. |
|
# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation. |
|
# "armeabi-v7a" - matches to the NDK ABI with the same name. |
|
# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation. |
|
# "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" - matches to the NDK ABI with the same name. |
|
# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation. |
|
# "mips" - matches to the NDK ABI with the same name |
|
# (It is not tested on real devices by the authos of this toolchain) |
|
# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation. |
|
# |
|
# ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for. |
|
# Option is read-only when standalone toolchain is used. |
|
# |
|
# ANDROID_TOOLCHAIN_NAME=arm-linux-androideabi-4.6 - the name of compiler |
|
# toolchain to be used. The list of possible values depends on the NDK |
|
# version. For NDK r8c the possible values are: |
|
# |
|
# * arm-linux-androideabi-4.4.3 |
|
# * arm-linux-androideabi-4.6 |
|
# * arm-linux-androideabi-clang3.1 |
|
# * mipsel-linux-android-4.4.3 |
|
# * mipsel-linux-android-4.6 |
|
# * mipsel-linux-android-clang3.1 |
|
# * x86-4.4.3 |
|
# * x86-4.6 |
|
# * x86-clang3.1 |
|
# |
|
# ANDROID_FORCE_ARM_BUILD=OFF - set ON to generate 32-bit ARM instructions |
|
# instead of Thumb. Is not available for "x86" (inapplicable) and |
|
# "armeabi-v6 with VFP" (is forced to be ON) ABIs. |
|
# |
|
# ANDROID_NO_UNDEFINED=ON - set ON to show all undefined symbols as linker |
|
# errors even if they are not used. |
|
# |
|
# ANDROID_SO_UNDEFINED=OFF - set ON to allow undefined symbols in shared |
|
# libraries. Automatically turned for NDK r5x and r6x due to GLESv2 |
|
# problems. |
|
# |
|
# LIBRARY_OUTPUT_PATH_ROOT=${CMAKE_SOURCE_DIR} - where to output binary |
|
# files. See additional details below. |
|
# |
|
# ANDROID_SET_OBSOLETE_VARIABLES=ON - if set, then toolchain defines some |
|
# obsolete variables which were used by previous versions of this file for |
|
# backward compatibility. |
|
# |
|
# 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. |
|

|
# 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. |
|

|
# 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 will be set true, mutually |
|
# exclusive. NEON option will be set true if VFP is set to NEON. |
|
# |
|
# LIBRARY_OUTPUT_PATH_ROOT should be set in cache to determine where Android |
|
# libraries will be installed. |
|
# Default is ${CMAKE_SOURCE_DIR}, and the android libs will always be |
|
# under the ${LIBRARY_OUTPUT_PATH_ROOT}/libs/${ANDROID_NDK_ABI_NAME} |
|
# (depending on the target ABI). This is convenient for Android packaging. |
|
