Ubuntu under Android NDK installation

Method 1.

1.google directly download the NDK source code decompression can be, the current version is android-ndk-r9d

Configuring $ndk_home and $PATH

Export ndk_home=/xxx/android-ndk-r9d
Export path= $NDK _home: $PATH

2. Extract Toolchain

Reference: docs/standalone-toolchain.html

A. Viewing the target instruction set arm or x86 or MIPS
B. Configure the directory for the header and root files used by the GCC compilation $SYSROOT

sysroot= $NDK _home/platforms/android-18/arch-arm
Export Sysroot

C. Invoking the NDK compiler

$NDK _home/build/tools/make-standalone-toolchain.sh--platform=android-18--install-dir=/tmp/my-android-toolchain

[--arch=x86] defaults to arm

D. Setting up $PATH and $CC (equivalent to the usual GCC)

Export Path=/tmp/my-android-toolchain/bin: $PATH
Export CC=ARM-LINUX-ANDROIDEABI-GCC # or export Cc=clang
Export cxx=arm-linux-androideabi-g++ # or export cxx=clang++

3. You can use $cc-o Hello hello.c

4. Upload Hello to Emulator

can be transferred to/data/under: adb push hello/data/

If the download is available: adb pull xx xx
