Apt HowTo
Chapter 6 Source Package
6.1 Download Source Pack
==============
In the world of free software, you often need to learn the source or deactivate the program, so you need to download them. The APT provides a simple way to help you get the source code for many programs in the release, and all files you need to create .deBS.
Another universal purpose of the Debian source code is to rewrite the new version of the unsteable release to use, for example, introducing a new package from the Stable release version, need to be regenerated. DEBS will be in the original release Association relationship migrates to a new release.
Complete these work, the / etc / apt / sources.list file should be a mirror source to be unsteable, don't forget to remove the annotation of the head. See the 2.1 / etc / APT / SOURFES.LIST file for details.
Download the source package with the following command:
Apt-Get Source PackageName
Three files are usually downloaded: a .orig.tar.gz, a .dsc and a .diff.gz. For DEBIAN-specific packages, the last file will not download, there is no "orig" item in the file name of the first file.
DPKG-SOURCE reads the .dsc file information, unpack the source package to the package-version directory, there is a debian / directory in the Source package downloaded, which is the file required to create a .deb package.
The source package you want to download is automatically compiled into a package, just add -b in the command line, as follows:
Apt-get -b source packagename
If you are not intended to create a .deb package now, you can run the following command, then create it.
DPKG-buildpackage -rfakeroot -UC -B
Run the above command in the directory where the download package is downloaded.
The Source command of the apt-get is different from its other commands. The normal user privileges can run the source command, and the specified file is downloaded to the user to call the apt-source package command.
6.2 Compile the package required by the source code package
==========================
