[x265] How to build the Makefile with cmake for iOS compiling?

[steven.Hu]

I found 'arm-linux' directory under 'build' directory, and I changed the 'crosscompile.cmake' to the following:


# CMake toolchain file for cross compiling x265 for ARM arch
# This feature is only supported as experimental. Use with caution.
# Please report bugs on bitbucket
# Run cmake with: cmake -DCMAKE_TOOLCHAIN_FILE=crosscompile.cmake -G "Unix Makefiles" ../../source && ccmake ../../source


set(CROSS_COMPILE_ARM 1)
set(CMAKE_SYSTEM_NAME Darwin)
set(CMAKE_SYSTEM_PROCESSOR armv7l)


# specify the cross compiler
set(CMAKE_C_COMPILER /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang)
set(CMAKE_CXX_COMPILER /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++)


# specify the target environment
SET(CMAKE_FIND_ROOT_PATH  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/)


Then I run 'cmake -DCMAKE_TOOLCHAIN_FILE=crosscompile.cmake -G "Unix Makefiles" ../../source && ccmake ../../source' from the arm-linux directory, and I got the'Makefile' without any error info.
But when run 'make', it reported many errors, which may be caused by incorrect headers including.I found the compiler uses the headers under '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk', instead, it should use the headers under '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/'.
How can I fix it? Any suggestion would be appreciated!
