LazPackager (formerly LazDebian) is a Lazarus design time package that allows creating Debian / Ubuntu Packages (and in the future also other packages like RPM or InnoSetup for Windows) from any existing Lazarus project with no or only minimal changes to the project and with only a few clicks of the mouse. You find it here:

Creating Debian binary package

select "Debian Options..." from the Project menu: screenshot menu "build deb options" ...and make sure everything is set up correctly, you need to provide valid names, email adddresses, description and also a license on the "debian/copyright" tab, default template is GPL-2. The default templates on the other debian/* tabs should be suitable for most projects out of the box. All changes you make to these templates and settings will be saved in the project file: screenshot settings dialog Now select "Build Debian Binary Package..." from the Run menu: screenshot build deb package Optionally sign it (for signing you need a gpg key for your email address, the same email address that you entered on the Debian settings dialog) screenshot build deb and now the package will be built (note that there may be lintian warnings at the end of the build, you should carefully inspect them, here we obviously did something wrong in our copyright file, it needs to be a special machine readable format documented by Debian but since it is flagged only as warning (W) and not as error (E) we will continue for now. screenshot messages window the binary package can be found in the DEBUILD folder in your project, its the file with .deb at the end, thats all that is needed to install it with dpkg -i: screenshot file manager If we look inside with archive manager we see what folders and files it contains: screenshot inside of package with archive manager and we could distribute this package to other computers and install it with dpkg -i or with gdebi and it would install its executable file into /usr/bin

Source package

LazDebian can also be used for creating a source package and upload it to your Launchpad PPA. Like above make sure all settings are correct, especially also the email address needs to correspond to your gpg key and the gpg key must be linked to your launchpad account. Also make sure you increment the version number if you upload the same package again (for example after a failed build and after fixing bugs). Select "Publish Debian Source Package..." and then in the next dialog optionally click "Sign" and "Upload": screenshot create src package after building and before upload it will ask for your pasphrase to sign the package: screenshot sign package and then it should upload and finish without errors: screenshot messages window, src package complete Soon after this you will receive a confirmation email from Launchpad: screenshot incoming mail from launchpad And on Launchpad you will see it start building (or enqueued for building soon): screenshot launchpad building and success: screenshot launchpad build complete if you have added the repository with apt-add-repository and after apt-get update you will be able to apt-get install the package soon after the build has completed.


Unfortunalely Ubuntu still has only Version 0.9.30 of Lazarus and also a pretty old FPC 2.4.4 on Precise (2.6 on Quantal). Your Project should compile and work locally with these old versions before you attempt to upload to launchpad (my example project from above did compile but does not run because I made it with Lazarus 1.0 and used properties in my lfm file that did not yet exist in older LCL, just in case anybody who is reading this tries to install the demo from the above PPA now).

An alternative would be to make a sophisticated makefile that would first download and install current FPC and Lazarus on their build server before starting the build of your project but this looks like a very hackish idea (but maybe someone might try just for fun).
