You're pretty close with your example steps, but here's what I'd suggest:
- Grab the sources with
apt-get source wine and
cd into the new directory
- Find what sort of patch system the wine package is based on:
what-patch; in this case, it tells us we that the wine package uses
quilt for patch management
- Since we're using quilt, add your custom patch(es) to the quilt series:
QUILT_PATCHES=debian/patches quilt import <your-patchfile.patch>If you have multiple patches, do this for each patch, in the order that you want them applied.
- Add a suitable entry to the
debian/changelog file - you'll need to alter the version number to ensure that your PPA version is differentiated from the official version. Typically, you should increment the last version number, and add a tilde (~) followed by your custom version string (eg
dch -i command can help with this too.
- Build the source package:
- Upload your source package to the PPA build system:
dput ppa:<your-ppa> ../wine*.changesThe <your-ppa> parameter is specified on the launchpad page for the PPA you want to upload it to (you'll have to create this beforehand).
It's usually a good idea to do a test build before doing the dput - the
pbuilder command allows you to recreate what the PPA build system would do with your package (ie, start from a clean install, add required deps, then build).
In this case you would have to set up pbuilder first (see https://wiki.ubuntu.com/PbuilderHowto), then do this before the
sudo pbuilder build ../*.dsc
