[boost for android 실행 (Boost source code 다운로드 및 빌드)]
1. boost for build에 명시되어 있는 표에 맞춰서 Andorid NDK 다운로드
Boost for Android
Boost for android is a set of tools to compile the main part of the Boost C++ Libraries for the Android platform.Currently supported boost versions are 1.45.0, 1.48.0, 1.49.0 and 1.53.0.To compile Boost for Android you may use one of the following NDKs:
|
* Android NDK 32bit version 사용 필요, build for boost가 인식 못함.
. Android NDK의 RELEASE.txt에서 64bit description을 제거해도 toolchaing등이 32bit에 맞춰 설정 되어 있음.
2. build-android 실행
* 다운받은 build for andoid 내 build-android.sh 실행
. option들 중에는 boost version을 정하는 --boost, 빌드 대상 library를 정하는 --with[out]-libraries 가 있음.

Valid options (defaults are in brackets):
--help Print this help.
--verbose Enable verbose mode.
--output=<path> Specify specific log output path (only terminal output by default)
--boost=<version> Boost version to be used, one of {1.53.0,1.49.0, 1.48.0, 1.45.0}, default is 1.53.0.
--clean Delete all previously downloaded and built files, then exit.
--download Only download required files and clean up previus build. No build will be performed.
--with-libraries=<list> Comma separated list of libraries to build.
--without-libraries=<list> Comma separated list of libraries to exclude from the build.

* 기본으로는 static library로 빌드가 되며 아래 메세지가 나와도 library들 빌드와 header 복사는 된 상태 임
. "./build-android.sh: 318: ./build-android.sh: Bad substitution"
* 몇건은 실패하는데.. 사실 system, filesystem, thread, date_time 정도만 있어도 문제는 없어서..
혹시나 더 필요하다면 좀 찾아봐야 하는데.. 귀찮음..
* 생성된 libraries는 JNI project에서 추가하여 사용하면 되고 만약 so를 사용할 것이라면 Android phone에 deploy하는 것을 확인해야 함.

[Android NDK를 사용한 Native 개발 시 참고]
* Android NDK 버전 마다 C++ library의 버전 차이로 인한 이슈 존재
Native에서 고급? C++ feature를 사용하는 경우.. 상용화 입장에서는 고생 함.
참고로 boost는 주 빌드 방법은 Android NDK + GNU_STL을 사용하고 RTTI, EXCEPTION feature는 제외하고 컴파일 함.
* NDK에서 지원하는 C++ library들의 조합은 다음과 같다.
system - Use the default minimal system C++ runtime library.
gabi++_static - Use the GAbi++ runtime as a static library.
gabi++_shared - Use the GAbi++ runtime as a shared library.
stlport_static - Use the STLport runtime as a static library.
stlport_shared - Use the STLport runtime as a shared library.
gnustl_static - Use the GNU STL as a static library.
gnustl_shared - Use the GNU STL as a shared library.
The capabilities of the various runtimes vary. See this table:
C++ C++ Standard
Exceptions RTTI Library
system no no no
gabi++ yes yes no
stlport yes yes yes
gnustl yes yes yes
. $ANDROID_NDK/doc 내 파일들 참고

* 팀원들의 NDK의 버전을 통일하는 것이 혹시나 모를 이상항 링크 에러 등을 방지하는데 도움
* Native library들을 빌드하는 NDK 버전과 Native library들이 사용하는 다른 native library들을 빌드한 NDK 버전을 통일하는 것을 추천
* JNI 빌드할때 모든 빌드 결과물의 arm, thumb mode를 맞춰라. 안 맞을 경우 원인 모를 crash 발생 가능하다.
