3 3 1. Tizen 개발환경구축

4 Tizen 개발도구 4 Source Code Management(SCM) Tools (Before build) Git, Repo, Gerrit Build Tool GBS(Git Build System) Packaging Tools (After build) MIC, RPM Tizen Platform IDE

5 개발환경구축과정요약 5 1. Git, Repo 설치 1. Git 설치 (8p) 2. Repo 설치 (15p) 2. Gerrit 서버에개발자등록및초기설정 1. Gerrit 개발자등록및초기설정 (19~24p) 3. GBS, MIC 설치 1. GBS 설치 (26p) 2. MIC 설치 (29p)

6 Git 6 A revision control and source management tool Features Free and open source(gnu GPL v2) Branching and merging Smaller and faster than other SCM tools Distributed Data assurance Staging area

7 Git: Key Concepts 7 Working directory: 실제파일 add command: staging area 에파일 / 디렉토리추가 Staging area(index): commit 될파일 commit command: 현재 staging area 를하나의버전으로서 repository 에반영 Repository(HEAD): 이미 commit 된 file Hash value 로식별되는 content-addressable object 로서보관됨.

8 Git: Commands 8 설치하기 $ sudo apt-get install git Repository 시작하기 새 repository 만들기 (init) $ git init Working directory 있는 repository 만들기 $ git init --bare Working directory 없는 repository 만들기 기존 repository 복제하기 (clone) 같은 PC 에 repository 가있는경우 $ git clone <local repository path> ex. git clone /home/user/tizen-platform 다른 PC 에 repository 가있는경우 $ git clone protocol://user@host:path ex. git clone ssh://user@review.tizen.org:external/systemd

9 Git: Commands 9 Staging area 에추가하기 (add) $ git add <file name> $ git add * Staging area 를하나의버전으로 commit $ git commit -m Description about this version $ git commit -a -m Description about this version -a: staging area 에자동으로추가하는옵션

10 Git: Commands 10 Local commit 을 remote repository 로밀어넣기 (push) $ git push <remote repository 이름 > <remote branch 이름 > Remote repository 이름의기본값 : origin Remote branch 이름의기본값 : master ex. git push origin master Remote repositor 의주소 (URI) 알려주기 해당 repository 가 remote repository 에서복제된것이아닌경우, remote repository 의주소를알려주면 push 명령사용가능 $ git remote add <remote repository 이름 > <remote repository 주소 > ex. git remote add origin ssh://user@review.tizen.org:external/systemd

11 Git: Commands 11 가지치기 (branch) 와합치기 (merge) 서로다른개발흐름을분리할때유용 Default branch: master 일반적으로는분리된 develop branch 를만들고, 이 branch 에서작업함. 하나의 topic 을추가하는개발과정을수행할때에도 topic 마다 branch 를하나씩만듦. Branch 의개발이끝나고나면원래 branch 로합침 (merge).

12 Git: Commands 12 새 branch 만들기 $ git branch <branch 이름 > ex. $ git branch feature_x 다른 branch 합치기 $ git merge < 합칠 branch 의이름 > ex. (master branch 로이동한후 feature_x 를 master 로합침 ) $ git checkout master $ git merge feature_x Branch 목록보여주기 $ git branch --list Remote branch reference 목록보여주기 $ git branch --remotes 다른 branch 로옮기기 (checkout) $ git checkout <branch 이름 >

13 Git: Commands 13 Commit log 보여주기 과거 commit 의 hash value 와 description 을보여줌 $ git log 이전 commit 으로옮기기 (checkout) $ git checkout <commit 의 hash value> ex. $ git log commit 783c82ff64eda9f de906ecad01f691 Author: Gyeonghwan Hong <redcarrottt@gmail.com> Date: Mon Sep 22 10:37: Second version commit: only prototype done commit bb31bf85430e1a027abe197e5b88a26110 Author: Gyeonghwan Hong <redcarrottt@gmail.com> Date: Thu Aug 28 12:08: initial version commit: there are only specification files $ git checkout bb31bf85430e1a027abe197e5b88a26110

Ubuntu 가영문이외의언어를사용하는경우, gbs 에서 Locale 이맞지않는오류가발생할수있음. 해결책 build.sh 에아래와같이 locale 을영어로맞추는코드삽입 # Locale 은 UTF-8 영어로설정되어있어야오류가생기지않음 export LANGUAGE=en_US.UTF-8 export LANG=en_US.UTF-8 export LC_ALL=en_US.UTF-8 locale-gen en_us.utf-8 dpkg-reconfigure locales ~/tizen-platform/build.sh
