liblastfm is a collection of libraries to help you integrate Last.fm services into your rich desktop software. It is officially supported software developed by Last.fm staff.

Fork it: http://github.com/lastfm/liblastfm
liblastfm dynamically links to:
- Qt 4.8 http://qt.nokia.com/
Additionally, to build you will need Ruby and GNU make (or Microsoft nmake).
Mac OS X
We recommend that you use Homebrew to install dependancies http://mxcl.github.com/homebrew/
brew install qt
Do something like this:
sudo apt-get install qt4-qmake pkg-config ruby g++ libqt4-dev
Please note, we have only tested on Linux, but we think it'll work on all varieties of UNIX. If it doesn't, report the bug to eartle on GitHub.
Install Ruby. Install Visual Studio 2008 or higher. Install Qt. Install the Windows Server 2003 Platform SDK r2:
Set up your environment variables so all include paths and tools are available.
Open a plain Windows shell, and see the next section.
mkdir _build && cd _build cmake .. sudo make install
We have copied the API at http://last.fm/api onto C++, so like you find artist.getInfo there you will find an lastfm::Artist::getInfo function in our C++ API. lastfm is a namespace, Artist a class and getInfo a function.
Thus the API is quite easy to learn. We suggest installing and checking the include/lastfm/* directory to find out all capabilities.
The demos directory shows some further basic usage including Audioscrobbling and getting metadata for music via our fingerprinting technology.
You need an API key from http://last.fm/api to use the webservice API.
Your link line needs to include the following:
-llastfm -lQtCore -lQtNetwork -lQtXml
Please set an identifiable UserAgent on your HTTP requests for the actual MP3s, in extreme cases we'll contact you directly and demand you do so :P
HTTP & Networking
You can specify your own QNetworkAccessManager derived class for liblastfm to use with lastfm::setNetworkAccessManager(). Our default is pretty good though, auto-determining proxy settings on Windows and OS X for instance.
- Header guards should be prefixed with LASTFM, eg. LASTFM_WS_REPLY_H
- #includes should be to the system path eg. #include <lastfm/Scrobbler.h>
- Don't make a header public unless it is absolutely required!
- All headers under src/ (not subfolders) are public by default
