It is needed because of explicit STL include paths. Otherwise some standard headers (like fenv.h) can not not be correctly found by the compiler.

# 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: http://code.google.com/p/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 ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
|
|
#
|
|
# ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for.
|
|
# Option is read-only when standalone toolchain is used.
|
|
#
|
|
# ANDROID_FORCE_ARM_BUILD=OFF - set ON to generate 32-bit ARM instructions
|
|
# instead of Thumb. Is not available for "x86" (inapplicable) and
|
|
# "armeabi-v6 with VFP" (is forced to be ON) ABIs.
|
|
#
|
|
# ANDROID_NO_UNDEFINED=ON - set ON to show all undefined symbols as linker
|
|
# errors even if they are not used.
|
|
#
|
|
# ANDROID_SO_UNDEFINED=OFF - set ON to allow undefined symbols in shared
|
|
# libraries. Automatically turned for NDK r5x and r6x due to GLESv2
|
|
# problems.
|
|
#
|
|
# LIBRARY_OUTPUT_PATH_ROOT=${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.
|
|

|
|
# 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.

|
|
# 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 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.
