Last.fm on Ubuntu Lucid Lynx (10.04)

Having recently got a nice shiny new netbook (an HP/Compaq 311c) I was trying to get last.fm to compile on it. My netbook was running a reasonably fresh install of Ubuntu Lucid Lynx (10.04).

So I downloaded the source for last.fm-1.4.2.58240 and unzipped it into my source directory. Knowing that it needed qt4 I then ran:
sudo apt-get install libqt4-dev

With that all installed I tried running ./configure in the source directory and it said everything was fine, so I went ahead and typed make.

After waiting while it compiled I was then greeted by the following error:
make[1]: Entering directory `/home/marvin/src/last.fm-1.4.2.58240/src/libFingerprint/fplib/pro_qmake'

marvin@Anjie:~/src/last.fm-1.4.2.58240$


Knowing that memcpy is part of the standard C library I thought this seemed a little strange. So I opened up last.fm-1.4.2.58240/src/libFingerprint/fplib/src/FingerprintExtractor.cpp and added the following line in bold:
#include <cmath>
#include <string.h>

Then recompiled.

The next error was the following:
g++ -c -pipe -O2 -w -fPIC -DNBREAKPAD -DLINUX -DNDEBUG -I/usr/share/qt4/mkspecs/linux-g++ -I. -I../../../../src -I../../../../build -I../../../libMoose -I../../../libUnicorn -I../include -I../src -I../../libs/fftw/src/api -I../../../../res/libsamplerate -o ../../../../build/fplib/release/OptFFT.o ../src/OptFFT.cpp

make: *** [sub-src-libFingerprint-fplib-pro_qmake-fplib-pro-make_default-ordered] Error 2
marvin@Anjie:~/src/last.fm-1.4.2.58240$


Which I fixed by editing last.fm-1.4.2.58240/src/libFingerprint/fplib/src/OptFFT.cpp to include the line in bold:
#include <iostream>
#include <memory.h> // for memcopy
#include <stdlib.h>

And then once again ran make.

The next error was:
g++ -c -pipe -O2 -w -D_REENTRANT -fPIC -DNBREAKPAD -DLINUX -DQT_NO_DEBUG -DQT_SQL_LIB -DQT_XML_LIB -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtNetwork -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtXml -I/usr/include/qt4/QtSql -I/usr/include/qt4 -I../../src -I../../build -I../libMoose -I../libUnicorn -Ifplib/include -I../src/ -I../../res/mad -I../../build/LastFmFingerprint/release -o ../../build/LastFmFingerprint/release/MP3_Source_Qt.o MP3_Source_Qt.cpp

make[1]: Leaving directory `/home/marvin/src/last.fm-1.4.2.58240/src/libFingerprint'
make: *** [sub-src-libFingerprint-make_default-ordered] Error 2


So I opened last.fm-1.4.2.58240/src/libFingerprint/MP3_Source_Qt.cpp and added the lines in bold:
#include <cassert>
#include <stdexcept>
#include <stdlib.h>
#include <limits.h>


And ran make once more.

This time it was a linking error:
g++ -Wl,-O1 -shared -Wl,-soname,libLastFmFingerprint.so.1 -o libLastFmFingerprint.so.1.0.0 ../../build/LastFmFingerprint/release/Sha256File.o ../../build/LastFmFingerprint/release/Sha256.o ../../build/LastFmFingerprint/release/MP3_Source_Qt.o ../../build/LastFmFingerprint/release/Fingerprinter2.o ../../build/LastFmFingerprint/release/FingerprintCollector.o ../../build/LastFmFingerprint/release/FingerprintQueryer.o ../../build/LastFmFingerprint/release/moc_Fingerprinter2.o ../../build/LastFmFingerprint/release/moc_FingerprintCollector.o ../../build/LastFmFingerprint/release/moc_FingerprintQueryer.o -L/home/marvin/src/last.fm-1.4.2.58240/bin -L/home/marvin/src/last.fm-1.4.2.58240/build/LastFmFingerprint/../fplib -L/usr/lib -lMoose -L/home/marvin/src/last.fm-1.4.2.58240/bin -lLastFmTools /home/marvin/src/last.fm-1.4.2.58240/build/fplib/libfplib.a -lsamplerate -lfftw3f -lQtSql -lQtXml -lQtGui -lQtNetwork -lQtCore -lpthread

So I ran sudo apt-get install libsamplerate0 libsamplerate0-dev libfftw3-dev libfftw3-3 libmad0-dev libmad0 libgpod-dev libgpod4 libasound2-dev and then ran make again.

If you're wondering how I came up with all the libraries above, it was just from running make several times and then using apt-cache search to search for the missing libraries. I didn't include these steps as they're a bit tedious.

Having done all that it's possible to run last.fm with bin/last.fm.sh.
