Android-NDK 다운로드

http://developer.android.com/tools/sdk/ndk/index.html

7z으로 압축해제

/usr/android-ndk 로 옮김

# mv ~Document/android-ndk/ /usr/android-ndk

.bashrc 에 PATH 등록

export PATH="/usr/android-ndk:$PATH"

환경설정 재 등록

# sourc .bashrc

추가 잘되었는지 확인

# $PATH 

테스트 실행

# ndk-build

아래 메세지가 나오면 path 설정 완료

Android NDK: Could not find application project directory !    

Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.    

/usr/android-ndk/build/core/build-local.mk:148: *** Android NDK: Aborting    .  Stop.
