-# ------------------------------------------------------------------------------
-#  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. And also can be found at
-#  http://code.opencv.org/projects/opencv/repository/revisions/master/changes/android/android.toolchain.cmake
-#
-#  Note: There are now two flavors of this toolchain file: 32-bit toolchain and 64-bit toolchain.
-#
-#  Usage Linux:
-#   $ export ANDROID_NDK_ROOT=/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_ROOT=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_ROOT%\prebuilt\windows\bin\make.exe" ..
-#   $ "%ANDROID_NDK_ROOT%\prebuilt\windows\bin\make.exe"
-#
-#
-#  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 ANDROID_NDK_ROOT. Can be set only at first cmake run.
-#
-#    ANDROID_STANDALONE_TOOLCHAIN=/opt/android-toolchain - path to the
-#      standalone toolchain. This option overrides ANDROID_NDK
-#      (and subsequentally the enviroment variable ANDROID_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" - matches to the NDK ABI with the same name.
-#           See ${ANDROID_NDK_ROOT}/docs/CPU-ARCH-ABIS.html for the documentation.
-#        "armeabi-v7a" - matches to the NDK ABI with the same name.
-#           See ${ANDROID_NDK_ROOT}/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 ${ANDROID_NDK_ROOT}/docs/CPU-ARCH-ABIS.html for the documentation.
-#        "mips" - matches to the NDK ABI with the same name
-#            (not testes on real devices)
-#
-#    ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for.
-#      Option is read-only when standalone toolchain used.
-#
-#    ANDROID_FORCE_ARM_BUILD=OFF - set true to generate 32-bit ARM instructions
-#      instead of Thumb-1. Is not available for "x86" (inapplicable) and
-#      "armeabi-v6 with VFP" (forced) ABIs.
-#
-#    ANDROID_NO_UNDEFINED=ON - set true to show all undefined symbols as linker
-#      errors even if they are not used.
-#
-#    ANDROID_SO_UNDEFINED=OFF - set true to allow undefined symbols in shared
-#      libraries. Automatically turned on for NDK r5x and r6x due to GLESv2
-#      problems.
-#
-#    LIBRARY_OUTPUT_PATH_ROOT=${CMAKE_SOURCE_DIR} - where to output binary
-#      files. See additional details below.
-#
-#    ANDROID_SET_OBSOLETE_VARIABLES=ON - it set, then toolchain defines some
-#      obsolete variables which were set by previous versions of this file for
-#      backward compatibility.
-#
-#
-#  What?:
-#    android-cmake toolchain searches for NDK/toolchain in the following order:
-#      ANDROID_NDK - cmake parameter
-#      ANDROID_NDK_ROOT - environment variable
-#      (ANDROID_NDK - environment variable as legacy fallback)
-#      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 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.

-#     [+] Addded Perl helper scripts to make it easier to build multiple architectures in one shot.
-#     [~] Breaking change of behavior to so that ANDROID_STANDALONE_TOOLCHAIN overrides ANDROID_NDK because the latter uses semi-standard environmental variables that people may already have defined for other conflicting purposes.
-#     [~] Changed environmental variable to look for ANDROID_NDK_ROOT because this is the semi-official/blessed one according to Google via the NDK mailing list. ANDROID_NDK is still checked for backwards compatibility.
-#     [~] Changed a lot of flags to try to match stock Android more closely due build problems I was trying to track down. In the end, I lost track of which specific flags were the problem. See Additional Notes for flag differences between this and stock.

-#     [~] Use -fstack-protector -no-canonical-prefixes -Wa,--noexecstack to match stock Android
-#     [~] Use -no-canonical-prefixes  -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now to match stock Android
-#     [~] Use -lc -lm to match stock Android
-#     [~] Removed -fsigned-char and -Wno-psabi because these don't appear in stock Android
-#     [~] Removed -f[no]exceptions flags from C flags because those are C++ options
-#     [~] Changed arm debug optimization level to O0 from Os
-#     [~] Added -funswitch-loops -finline-limit=300 to match stock Android
-#     [~] Changed arm debug optimization level to O0 from Os
-#     [~] Separated ANDROID_CXX_FLAGS into ANDROID_CXX_FLAGS and ANDROID_C_FLAGS
-#     [*] Note: MIPs settings were not changed/tested.
-#

-# -O0 -UNDEBUG (debug only, not in release)
-# -fno-omit-frame-pointer -fno-strict-aliasing (debug only, not in release)
-#
-# -DANDROID  -Wa,--noexecstack
-
-# The link flags are:
-
-
-# armeabi
-# -Wl,-soname,libhello-jni.so -shared
-# --sysroot=/fee/android-ndk/platforms/android-14/arch-arm
-# /foo/hello-jni.o
-# -no-canonical-prefixes  -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now  -lc -lm

-
-
-# Some interesting observations are that debug doesn't have different flags, but overrides set flags with additional switches.
-
-# Differences from Stock Android:
-# This toolchain has deviated from the stock flags.
-#
-# I don't do the override technique as described directly above.
-#
-# -ffunction-sections has been separated into the option ANDROID_FUNCTION_LEVEL_LINKING.
-# But this also brings in -fdata-sections and the linker flags -Wl,--gc-sections which are not in the Android defaults
-#
-# -funwind-tables has been completely removed for arm by this file. It looks like the author intentionally did this for performance.
-#
-# Optimization flags are using O3 in this file as opposed to stock 02 for Release. It looks like the original authors have done some benchmarking so I am deferring to them.
-# I am however changing the Os to O0 for debug.

+# ------------------------------------------------------------------------------
+#  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. And also can be found at
+#  http://code.opencv.org/projects/opencv/repository/revisions/master/changes/android/android.toolchain.cmake
+#
+#  Note: There are now two flavors of this toolchain file: 32-bit toolchain and 64-bit toolchain.
+#
+#  Usage Linux:
+#   $ export ANDROID_NDK_ROOT=/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_ROOT=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_ROOT%\prebuilt\windows\bin\make.exe" ..
+#   $ "%ANDROID_NDK_ROOT%\prebuilt\windows\bin\make.exe"
+#
+#
+#  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 ANDROID_NDK_ROOT. Can be set only at first cmake run.
+#
+#    ANDROID_STANDALONE_TOOLCHAIN=/opt/android-toolchain - path to the
+#      standalone toolchain. This option overrides ANDROID_NDK
+#      (and subsequentally the enviroment variable ANDROID_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" - matches to the NDK ABI with the same name.
+#           See ${ANDROID_NDK_ROOT}/docs/CPU-ARCH-ABIS.html for the documentation.
+#        "armeabi-v7a" - matches to the NDK ABI with the same name.
+#           See ${ANDROID_NDK_ROOT}/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 ${ANDROID_NDK_ROOT}/docs/CPU-ARCH-ABIS.html for the documentation.
+#        "mips" - matches to the NDK ABI with the same name
+#            (not testes on real devices)
+#
+#    ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for.
+#      Option is read-only when standalone toolchain used.
+#
+#    ANDROID_FORCE_ARM_BUILD=OFF - set true to generate 32-bit ARM instructions
+#      instead of Thumb-1. Is not available for "x86" (inapplicable) and
+#      "armeabi-v6 with VFP" (forced) ABIs.
+#
+#    ANDROID_NO_UNDEFINED=ON - set true to show all undefined symbols as linker
+#      errors even if they are not used.
+#
+#    ANDROID_SO_UNDEFINED=OFF - set true to allow undefined symbols in shared
+#      libraries. Automatically turned on for NDK r5x and r6x due to GLESv2
+#      problems.
+#
+#    LIBRARY_OUTPUT_PATH_ROOT=${CMAKE_SOURCE_DIR} - where to output binary
+#      files. See additional details below.
+#
+#    ANDROID_SET_OBSOLETE_VARIABLES=ON - it set, then toolchain defines some
+#      obsolete variables which were set by previous versions of this file for
+#      backward compatibility.
+#
+#
+#  What?:
+#    android-cmake toolchain searches for NDK/toolchain in the following order:
+#      ANDROID_NDK - cmake parameter
+#      ANDROID_NDK_ROOT - environment variable
+#      (ANDROID_NDK - environment variable as legacy fallback)
+#      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 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.

+#     [+] Addded Perl helper scripts to make it easier to build multiple architectures in one shot.
+#     [~] Breaking change of behavior to so that ANDROID_STANDALONE_TOOLCHAIN overrides ANDROID_NDK because the latter uses semi-standard environmental variables that people may already have defined for other conflicting purposes.
+#     [~] Changed environmental variable to look for ANDROID_NDK_ROOT because this is the semi-official/blessed one according to Google via the NDK mailing list. ANDROID_NDK is still checked for backwards compatibility.
+#     [~] Changed a lot of flags to try to match stock Android more closely due build problems I was trying to track down. In the end, I lost track of which specific flags were the problem. See Additional Notes for flag differences between this and stock.
+#     [~] Changed armeabi-v7a to use -mfpu=vfpv3-d16 instead of -mfpu=vfp to conform with stock Android.
+#     [~] Changed VFPV3 mode to use -mfpu=vfpv3-d32
+#     [~] Use --sysroot=${ANDROID_SYSROOT} to match stock Android
+#     [~] Use -fstack-protector -no-canonical-prefixes -Wa,--noexecstack to match stock Android
+#     [~] Use -no-canonical-prefixes  -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now to match stock Android
+#     [~] Use -lc -lm to match stock Android
+#     [~] Removed -fsigned-char and -Wno-psabi because these don't appear in stock Android
+#     [~] Removed -f[no]exceptions flags from C flags because those are C++ options
+#     [~] Changed arm debug optimization level to O0 from Os
+#     [~] Added -funswitch-loops -finline-limit=300 to match stock Android
+#     [~] Changed arm debug optimization level to O0 from Os
+#     [~] Separated ANDROID_CXX_FLAGS into ANDROID_CXX_FLAGS and ANDROID_C_FLAGS
+#     [*] Note: MIPs settings were not changed/tested.
+#
+#
+# (EW) Additional Notes:
+# Looking at the switches used by compiling the hello-jni example from ndk-build V=1 in r8d, I see the following compiler flags:
+# armeabi
+# -MMD -MP -MF /foo/hello-jni.o.d
+# -fpic -ffunction-sections -funwind-tables -fstack-protector
+# -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__ -no-canonical-prefixes

+# -O0 -UNDEBUG (debug only, not in release)
+# -fno-omit-frame-pointer -fno-strict-aliasing (debug only, not in release)
+#
+# -DANDROID  -Wa,--noexecstack
+
+# The link flags are:
+
+
+# armeabi
+# -Wl,-soname,libhello-jni.so -shared
+# --sysroot=/fee/android-ndk/platforms/android-14/arch-arm
+# /foo/hello-jni.o
+# -no-canonical-prefixes  -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now  -lc -lm
+
+# armeabi-v7a
+# -Wl,-soname,libhello-jni.so -shared
+# --sysroot=/fee/android-ndk/platforms/android-14/arch-arm
+# /foo/hello-jni.o
+# -no-canonical-prefixes -march=armv7-a -Wl,--fix-cortex-a8 -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now  -lc -lm

+# -no-canonical-prefixes  -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now  -lc -lm
+
+
+# Some interesting observations are that debug doesn't have different flags, but overrides set flags with additional switches.
+
+# Differences from Stock Android:
+# This toolchain has deviated from the stock flags.
+#
+# I don't do the override technique as described directly above.
+#
+# -ffunction-sections has been separated into the option ANDROID_FUNCTION_LEVEL_LINKING.
+# But this also brings in -fdata-sections and the linker flags -Wl,--gc-sections which are not in the Android defaults
+#
+# -funwind-tables has been completely removed for arm by this file. It looks like the author intentionally did this for performance.
+#
+# Optimization flags are using O3 in this file as opposed to stock 02 for Release. It looks like the original authors have done some benchmarking so I am deferring to them.
+# I am however changing the Os to O0 for debug.
