Warning: I kept the same variable name because this file will be rewritten fairly soon since most of its code no longer applies to SFML and becomes incorrect (too hard to maintain). Thus stlport variable names refers to libc++ stuff. E.g: ANDROID_USE_STLPORT=1 turns the use of libc++ on.

# Android CMake toolchain file, for use with the Android NDK r9d
|
|
# 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 was forked from the OpenCV project. This version is maintained by
|
|
# the SFML project and can be found at http://github.com/LaurentGomila/SFML
|
|
# (cmake/toolchains/android.toolchain.cmake). It brings support for the
|
|
# latest NDK versions.
|
|
#
|
|
# 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" ..
|
|
# $ "%ANDROID_NDK%\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. 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 ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
|
|
# "mips" - matches to the NDK ABI with the same name
|
|
# (not testes on real devices)
|
|
#
|
|
# ANDROID_NATIVE_API_LEVEL=android-9 - level of Android API compile for.
|
|
# Option is read-only when standalone toolchain used.
|
|
#
|
|
# ANDROID_FORCE_ARM_BUILD=OFF - set true to generate 32-bit ARM instructions
|
|
# instead of Thumb-1. Is not available for "x86" (inapplicable) and
|
|
# "armeabi-v6 with VFP" (forced) ABIs.
|
|
#
|
|
# ANDROID_NO_UNDEFINED=ON - set true to show all undefined symbols as linker
|
|
# errors even if they are not used.
|
|
#
|
|
# ANDROID_SO_UNDEFINED=OFF - set true to allow undefined symbols in shared
|
|
# libraries. Automatically turned on for NDK r5x and r6x due to GLESv2
|
|
# problems.
|
|
#
|
|
# LIBRARY_OUTPUT_PATH_ROOT=${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 - 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 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.
