To build, do the following:

——— 1. Build despotify
a. First, get despotify: http://despotify.se/source-code/

b. Then, install the requirements to build despotify as instructed on their webpage. Something like this:

aptitude install libssl-dev zlib1g-dev libvorbis-dev libtool libncursesw5-dev
aptitude install libgstreamer-plugins-base0.10-0 libgstreamer0.10-dev

c. Build and “make install”.

——— 2. Build Qt
a. You need Qt 4.6 to build qtspotify. If you are building for Maemo 5, get the Maemo 5-branch of Qt 4.6: http://qt.gitorious.org/qt/qt-x11-maemo

b. Configure it with options “-opengl es2” and “-maemo5”. See more information here: http://labs.trolltech.com/blogs/2009/10/09/qt-on-the-n900/

c. Build and “make install” at least src/corelib and src/gui.

——— 3. Build qtspotify
a. QtSpotify requires alsa-dev files, so get the package:

aptitude install libasound2-dev

Once you have all the requirements, building should be as simple as:

b. qmake
c. make

When everything has been built, you will need the following available on the device where you want to run the application:

a. All runtime requirements for despotify.
b. The qtspotify application binary
c. The libraries libQtCore.so.4 and libQtGui.so.4 from $QTDIR/lib
d. The library libdespotify.so.0 from $DESPOTIFYDIR/src/lib/.libs

Good luck!
