1 This directory contains support files to build libc++ with 2 the Android NDK for ARM, x86 and MIPS. 3 4 You need a recent NDK release, one which provides a version 5 of the GAbi++ C++ runtime that supports rtti _and_ exceptions. 6 7 Build instructions: 8 9 1/ Set NDK to the path of a recent Android NDK install path 10 (Use Android NDK r8c or above), e.g.: 11 12 NDK=$HOME/android/ndk-r8c 13 14 2/ From the top-level directory, do: 15 16 $NDK/ndk-build -C android/test 17 18 This is actually equivalent to: 19 20 cd android/test 21 $NDK/ndk-build 22 23 3/ To see build commands, use V=1, as in: 24 25 $NDK/ndk-build -C android/test V=1 26 27 28 Android support files: 29 30 include/support/android: 31 Android system header wrappers, to add missing declarations 32 33 src/support/android: 34 Put the implementation of the missing system functions here. 35 36 android/llvm-libc++/Android.mk: 37 Main build file for the library. This builds one static and 38 one shared version of the library. 39 40 If modifications are not obvious, read $NDK/docs/ANDROID-MK.html 41 for a description of the Android.mk format. 42 43 android/test/jni: 44 NDK build project for two test programs that link against the 45 static and shared versions of the library. 46 47 See the Android.mk and Application.mk files in this directory 48 if you want to add new test files. 49 50 51 Toolchain selection: 52 By default, ndk-build tries to build with GCC 4.6, however, experimental 53 versions of GCC 4.7 and Clang 3.1 are available with recent NDK releases. 54 55 Use the NDK_TOOLCHAIN_VERSION environment variable to switch to a 56 different one, valid examples: 57 58 59 export NDK_TOOLCHAIN_VERSION=4.6 # this is the default 60 $NDK/ndk-build -C android/test 61 62 # This is equivalent, but for GCC 4.7 63 $NDK/ndk-build -C android/test NDK_TOOLCHAIN_VERSION=4.7 64 65 # Also equivalent, but for Clang 3.1 66 NDK_TOOLCHAIN_VERSION=Clang3.1 $NDK/ndk-build -C android/test 67
