+# Android CMake toolchain file, for use with the ndk r5,r6,r7
# See home page: http://code.google.com/p/android-cmake/
#
# Usage Linux:
# $ make
#
# Usage Linux (using standalone toolchain):
-# $ export ANDROID_
NDK_TOOLCHAIN_ROOT=/<absolute path to standalone toolchain>
+# $ export ANDROID_
STANDALONE_TOOLCHAIN=/<absolute path to standalone toolchain>
# $ cmake -DCMAKE_TOOLCHAIN_FILE=<path to this file>/android.toolchain.cmake ..
# $ make
#
# Usage Windows:
# You need native port of make to build your project.
+# NDK r7 already has make.exe on board. For older versions you need to intall it seperately.
# For example this one: http://gnuwin32.sourceforge.net/packages/make.htm
#
-# $ SET ANDROID_NDK=C:\<absolute path to NDK>\android-ndk-r6b
-# $ cmake.exe -G"Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=<path to this file>\android.toolchain.cmake -DCMAKE_MAKE_PROGRAM=C:\<absolute path to make>\make.exe ..

#
# Toolchain options (can be set as cmake parameters: -D<option_name>=<value>):
-# ANDROID_NDK=/opt/android-ndk-r6b - path to NDK root.
-# Can be set as environment variable.
+# ANDROID_NDK=/opt/android-ndk-r7 - path to NDK root.
+# Can be set as environment variable. Can be set only at first cmake run.
#
-# ANDROID_NDK_TOOLCHAIN_ROOT=/opt/android-toolchain - path to standalone toolchain.
+# ANDROID_STANDALONE_TOOLCHAIN=/opt/android-toolchain - path to standalone toolchain.
# Option is not used if full NDK is found. Can be set as environment variable.
+# Can be set only at first cmake run.
#
-# ANDROID_API_LEVEL=android-8 - level of android API to use.
-# Option is ignored when build uses stanalone toolchain.
+# ANDROID_ABI=armeabi-v7a - type of floating point support.
+# Other possible values are: "armeabi", "armeabi-v7a with NEON", "armeabi-v7a with VFPV3", "armeabi-v6 with VFP", "x86"
#
-# ARM_TARGET=armeabi-v7a - type of floating point support.
-# Other possible values are: "armeabi", "armeabi-v7a with NEON", "armeabi-v7a with VFPV3"
+# ANDROID_NATIVE_API_LEVEL=android-8 - level of android API to use.
+# Option is read-only when build uses stanalone toolchain.
#
-# FORCE_ARM=false - set true to generate 32-bit ARM instructions instead of Thumb-1.
+# ANDROID_FORCE_ARM_BUILD=OFF - set true to generate 32-bit ARM instructions instead of Thumb-1.
+# Is not available for "x86" (missing) and "armeabi-v6 with VFP" (forced) ABIs.
#
-# NO_UNDEFINED=true - set true to show all undefined symbols will as linker errors even if they are not used.
+# ANDROID_NO_UNDEFINED=ON - set true to show all undefined symbols as linker errors even if they are not used.
#
+# LIBRARY_OUTPUT_PATH_ROOT=${CMAKE_SOURCE_DIR} - where to output binary files. See details below.
#
-# Toolcahin will search for NDK/toolchain in following order:
+# ANDROID_SET_OBSOLETE_VARIABLES=ON - it set, then toolchain define some obsolete variables which
+# was set by previous versions of this file for backward compatibility.
+#
+# android-cmake toolcahain will search for NDK/toolchain in the following order:
# ANDROID_NDK - cmake parameter
# ANDROID_NDK - environment variable
+# ANDROID_STANDALONE_TOOLCHAIN - cmake parameter
+# ANDROID_STANDALONE_TOOLCHAIN - environment variable
# ANDROID_NDK - default location
-# ANDROID_NDK_TOOLCHAIN_ROOT - cmake parameter
-# ANDROID_NDK_TOOLCHAIN_ROOT - environment variable
-# ANDROID_NDK_TOOLCHAIN_ROOT - default location
+# ANDROID_STANDALONE_TOOLCHAIN - default location
#
#
# What?:
# Make sure to do the following in your scripts:
-# SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${my_cxx_flags}")
-# SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${my_cxx_flags}")
+# SET( CMAKE_CXX_FLAGS "${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.
#
# ANDROID and BUILD_ANDROID will be set to true, you may test these
# variables to make necessary changes.
#
-# Also ARMEABI and ARMEABI_V7A will be set true, mutually exclusive. V7A is
+# Also ARMEABI or ARMEABI_V7A or X86 will be set true, mutually exclusive. V7A is
# for floating point. NEON option will be set true if fpu is set to neon.
#
# LIBRARY_OUTPUT_PATH_ROOT should be set in cache to determine where android
# [~] allowed spaces in NDK path
# - modified September 2011 Andrey Kamaev andrey.kamaev@itseez.com
# [~] updated for NDK r6b
+# - modified November 2011 Andrey Kamaev andrey.kamaev@itseez.com
+# [~] rewritten for NDK r7
+# [+] x86 toolchain support (experimental)
+# [~] improved compiler and linker flags management
+# [+] support different build flags for Release and Debug configurations
+# [~] by default compiler flags the same as used by ndk-build (but only where reasonable)
+# [~] ANDROID_NDK_TOOLCHAIN_ROOT is splitted to ANDROID_STANDALONE_TOOLCHAIN and ANDROID_TOOLCHAIN_ROOT
+# [~] ARM_TARGET is remaned to ANDROID_ABI
+# [~] ARMEABI_NDK_NAME is renamed to ANDROID_NDK_ABI_NAME
+# [~] ANDROID_API_LEVEL is renamed to ANDROID_NATIVE_API_LEVEL
