Maemo 5 PR 1.2 is out with Qt 4.6.2 installed, so developers now can create applications with Qt 4.6 using either the official scratchbox based SDK or MADDE (remember, “MADDE is currently a technology preview.”)
BUT… there are people who prefer “Livin’ on the Edge“. If you are one of those and already want/need to develop with Qt 4.7 (not released yet!) for Maemo 5, using MADDE to build your applications / packages, here is an update to the procedure first published by the troll Harald Fernengel (AKA harryF). Although the title says “on MacOS X”, the steps also work on Linux.
Step-by-step:
- Install MADDE. Download it here.
- If you are not using a Debian based distro, you need to install the “Tools for Debian Packages” package of your distribution (e.g. “deb” on openSUSE, sys-apps/debianutils on Gentoo).
- Download the script fetch-qt4.7.0-latest.sh. This script downloads the libqt4-experimental packages from repository.maemo.org and installs then in your MADDE – Before you run the script, remember to adjust the MADDE_PATH variable according to the path you installed MADDE.
- Download qt4-tools-latest.tar.gz. It contains the Qt tools compiled for the correspondent version, configured for cross compiling. Extract to /opt/qt4-maemo5.
- Check if mad is in your PATH.
To build an application using your fresh environment, run /opt/qt4-maemo5/bin/qmake && make .
If you succeeded in the setup process, this should result in a armel binary ready to run on N900. To generate a deb package, you can use the tools offered by MADDE to build a skeleton of debian package and so on.
To run your application on N900, install libqt4-experimental-* packages. If QtQuick (QML) is part of your plans, qmlviewer is in the package qt4-experimental-declarative-qmlviewer .
