Get master code from git repository located at butaca repo
Remove unsupported libraries
Check control file to see deps of this apps. At first shight, it dependends of applauncherd and ShareUI. Right now, theres no replacement for this on Fremantle, so functionality provided should be removed.
Applauncherd
Provides a boost at instantiation time for apps that link with it. You could see more info at Harmmatan API Docs Besides that, provides invoker a tool to launch programs and add splashscreen while application is starting.
We are going to loose splash screen
To remove this library, lookup for MDeclarativeCache inside code. Once again grep is your friend. Once located, replace it by standard QApplication and QDeclarativeView classes.

And remove boostable deps from project files.

ShareUI
Refactor QML files
As on [QtComponents/Miniature], we need to replace namespace by the fremantle one. In this case we need to go a bit further use migrateTo for this task.
Update hardcoded paths
Remove QtQuick 1.1 code
commit.
Handle Close events
This is easy in this case.

commit
Adapt deployment to Fremantle
Some changes on how Butaca is deployed are needed to match Fremantle requirements.
Optify code
Update Desktop file
And finally, update desktop file. There's no applauncerd on fremantle, so remove invoker from Exec. With this action we loose splash-screen.
commit
Update packing scripts
Now that all required changes are commited. generate patches with <syntaxhighlight lang="bash">git format-patch origin/master</syntaxhighlight> and copy generated files into debian/patches directory.
Finally, modify rules file at debian directory to merge patches. At config-stamp rule add: <syntaxhighlight lang="make">for p in debian/patches/*; do patch -p1 < $$p; done </syntaxhighlight>
And thats all. You have Butaca working on Maemo5
