Publish project on Launchpad

From Free Pascal wiki
Jump to: navigation, search

Launchpad is default Ubuntu build system. It allows us to register own project and let build server build our application. But web interface is overcomplicated and it is not easy to setup build of Lazarus project. Here this wiki pages can help.

It is not simply possible to get own application package immediately directly to standard Ubuntu packages. Such package needs to comply with several rules to be accepted as standard distribution package. But Launchpad also supports PPA (Personal Package Archives) which is place where non distribution packages can be prepared.

Build package on Launchpad

  • First register new user account or login to your existing user account
  • After the project is created you can import source code from external repository to Launchpad Bazaar project repository. Go to Code section and click to Configure code link. Then fill required fields and click to Update button.
  • Create debian directory under your project. It doesn't need to be in branch root directory. It will be appended to branch from specified location. The directory need to contain several debian package specific files.

source/format:

3.0 (quilt)
  • Now also in Code section of the project click to Import a branch link on right panel. Fill branch name with debian-packaging and as source select import from location where debian directory for the application is stored. If you create multi-platform application then usually debian directory is not stored in root of your application branch but rather in some subdirectory. Then click to Request import.
  • Create recipe for branch:
# bzr-builder format 0.3 deb-version {debupstream}-0~{revno}
lp:custom-app
nest packaging lp:~user/application-name/debian-packaging debian
  • Click to Request build(s) link to start build process

Build package locally

You can also build your deb package locally outside of launchpad. Just create script called for example build.sh. This script will copy your project files with debian subdirectory to temporary directory where build process will be started and new deb package created.

#!/bin/bash
 
BUILD_ROOT=/tmp/build-root/application-name
mkdir -p $BUILD_ROOT
cp -r -f . $BUILD_ROOT
cd $BUILD_ROOT
dpkg-buildpackage -b -rfakeroot -us -uc

After execution new package will be placed in /tmp/build-root.
