앞선 글을 읽고...
[프로그래밍/Linux/Ubuntu] - Linux(리눅스) Makefile 예제,강좌 (debug/release 경로 분리, rebuild, 자동 dependency)
이 글의 연속 선상입니다.
앞선 글에서는, 일반적인 /trunk/... 단위의 상대적인 경로 입력이 지원되지 않았습니다.
이번 글에서는 /trunk/... 단위의 상대적인 경로 입력이 지원되고,
.so 파일 빌드와 해당 테스트를 할 수 있는 빌드도 포함됩니다.
자세한 설명은 이전글을 참고 바라며,
.so 빌드를 위한 설정등은 해당 makefile을 참고하시기 바랍니다.
예제
libmodule.zip
빌드 & 테스트
압축을 $HOME, 즉, ~/trunk로 압축을 풀었다고 가정합니다.
cd ~/trunk/src/libmodule
make debug
make release
를 통해 libmodule.so의 debug/release를 빌드합니다.
cd ~/trunk/src/libmodule.test
make debug
make release
를 통해 libmoduletest.run의 debug/release를 빌드합니다.
cd ~/trunk/src/build/linux/native/release 혹은
cd ~/trunk/src/build/linux/native/debug
./libmoduletest.run
을 실행하면,
Success to load module
[a.cpp] hello
[b.cpp] world
[libmodule.cpp] say good-bye!
이 생성됩니다.

* src 쪽 경로는 아무 변경이 없습니다.
* .d와 .o 파일은 intermediate 쪽으로 격리되어 저장됩니다.
특징
.so 빌드시, 즉, ./trunk/src/libmodule/Makefile의 POST_BUILD step에,
$(STRIP) $(TARGET);
가 포함되어 있습니다.
그래서, so 빌드에 불필요한 심볼 정보등은 제거됩니다.
또한, ./trunk/src/libmodule/ld_conf.lds에,
"libmodule_*"로 시작되는 함수만 export 가능하도록 하였습니다.
그래서, 만일, Export할 API는 항상 libmodule_로 시작하도록 가정해야 합니다.
