QtComponents/Butaca
Butaca is an application to fetch movie-related information. You could see a more detailed description at its home page.

[edit] 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.
[edit] 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.

[edit] ShareUI
Share UI is a set of libraries and executables that implements platform-wide selection of destinations to share content. See project README for details.
Right now, we are going to support for this library (By the way, it seems portable to maemo5 without LMT. Any volunteers ?). Butacas defines a ButacaController class to share user preferences with others. So, we follow a 2 step approach
[edit] Hide ShareUI from C++ Code
Easy. we Just use Q_WS_MAEMO_5 and Q_WS_SIMULATOR to get this code compilable on Maemo5 and QtSimulator.

[edit] 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.
[edit] Update namespace
Use [QtComponents/migrateTo], sed or an app like regexxer. See [QtComponents/Miniature] for required changes
[edit] Hardcoded Paths
Butaca fetch Properties directly from UIConstants.js js library. This library is private to QtComponents, so it uses a file://point/to/uiConstants.js schemas that we should also change.
See QtComponents/ThemeHowto for a better (and non upstream portable) way of doing this.
[edit] Remove QtQuick 1.1 code
Reached this point. Project should be runnable on QtSimulator. Use QtSimulator 1.1. If we get console.log errors, it would be produced by unsupported QtQuick 1.1 code.
<syntaxhighlight lang="bash"> PATH/TO/QTSIMULATOR 1.1/Qt/gcc/bin/qmake butaca.pro && make && ./butaca </syntaxhighlight>

[edit] Adapt deployment to Fremantle
Some changes on how Butaca is deployed are needed to match Fremantle requirements.
[edit] Deployment
Add minimal changes to fit fremantle
[edit] Optify
Point binary to /opt and adapt paths to Fremantle

[edit] 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 cdbs rules definition add: <syntaxhighlight lang="make">include /usr/share/cdbs/1/rules/simple-patchsys.mk </syntaxhighlight>
