Android 編譯NDK

記錄一下自己編譯NDK的方法。目錄結構：

 

～/src  --android源碼目錄

～/android-ndk-r6 --google NDK目錄

1. 編譯系統

 

a. source build/envsetup.sh
b. choosecombo Device release msm8660_surf eng
c. make

2.  build 

 

a.src$ cd ndk/
b.src$ ./build/tools/build-ndk-sysroot.sh 會得到 "ndk/build/platforms" 目錄
c.src$ ./build/tools/build-platforms.sh  得到 ""src/ndk/samples" 跟 "src/ndk/platforms"目錄

 

3.將我們自己的 src/prebuilt/ 的 toolchain 覆蓋android-ndk-r6 裏面的相應文件

 

a. src$ cp -af build/platforms/android-3  ../android-ndk-r6/platforms/

b. src$ cp -af prebuilt/linux-x86/toolchain/arm-linux-androideabi-4.4.x/*
           ../android-ndk-r6/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/

c. src$ cp prebuilt/android-arm/gdbserver/gdbserver
           ../android-ndk-r6/toolchains/arm-linux-androideabi-4.4.3/prebuilt/

 

4 測試 hello-jni

 

$cd android-ndk-r6/samples/hello-jni
$ ./../../ndk-build
Gdbserver
: [arm-linux-androideabi-4.4.3]
libs/armeabi/gdbserver
Gdbsetup : libs/armeabi/gdb.setup
Compile thumb : hello-jni <= hello-jni.c
SharedLibrary : libhello-jni.so
Install
: libhello-jni.so => libs/armeabi/libhello-jni.so
BFD:
～/android-ndk-r6/samples/hello-jni/libs/armeabi/
st0hXUMa: warning: sh_link not set for section `.ARM.exidx'

build成功

5. In Eclipse:
a.Click File > New Android Project...
b.Select the Create project from existing source radio button.
c.Select any API level above Android 3.1.
d.In the Location field, click Browse... and select the
<ndk-root>/samples/hello-jni directory.
e.Click Finish.
