Pre-installation

sudo apt-get install -y debmake

터미널에서 bash를 사용하면 ~/.bashrc, zsh을 사용하면 ~/.zshrc의 마지막 줄에 아래와 같은 코드를 삽입합니다.

export DEBEMAIL="hhk7734@gmail.com"
export DEBFULLNAME="Hyeonki Hong"

Creating template files

아래 명령어를 통해 <package>와 동일한 디렉토리에 <package>-<version>, <package>-<version>.tar.gz, <package>_<version>.orig.tar.gz이 생성됩니다.

생성된 template files은 <package>-<version> 디렉토리에서 확인 가능합니다.

<package>디렉토리로 이동 후 아래 명령어를 실행합니다.

debmake -t -p <package> -u <version> [-r <revision>] -x[0-4]

Examples

$ debmake -t -p <package> -u <version> [-r <revision>] -x0

changelog

Ref: https://www.debian.org/doc/debian-policy/ch-source.html#s-dpkgchangelog

changelog가 없으면 아래 명령어로 생성할 수 있습니다.

dch --create [--package <package>]

changelog가 있으면 아래 명령어로 로그를 추가할 수 있습니다. distribution 상태가 UNRELEASED 상태면 change detail이 추가되고, 다른 상태면 다음 version이 추가됩니다.

dch -i

changelog는 형식이 존재합니다. 형식에 맞지 않는 changelog를 사용하면 패키지 빌드 시 오류가 발생할 수 있습니다.

[package] (version) distribution; urgency=urgency
  [optional blank line(s), stripped]
  * change details
  more change details
  [blank line(s), included in output of dpkg-parsechangelog]
  * even more change details
  [optional blank line(s), stripped]
 -- Name <email>  date

rules

debhelper에 의해 패키지가 빌드 될 때, 각 단계에 실행되는 명령을 수정할 수 있는 파일입니다.

#!/usr/bin/make -f

<package>.cron.*

• package.cron.hourly - Installed as /etc/cron.hourly/package; run once an hour.

install (<package>.install)

표준 make install이 하지 않는 파일 설치 목록 입니다. 파일 명과 설치되어야할 위치를 한 줄에 하나씩 적으면 됩니다. 패키지 안에서 파일의 상대 경로와 설치될 경로가 동일한 경우 파일 명만 작성해도 됩니다.

usr/local/bin/A
lib/B /usr/local/lib

위처럼 작성한 경우 /usr/local/bin/A, /usr/local/lib/B가 설치됩니다.
