Compilation (de Qemu). Erreur : "cannot find -lm"

Bonjour,

Je viens de voir que les sources CVS de Qemu corrigent le bug qui
m'enpêchent d'utiliser mon lecteur de disquette.
Je souhaite donc les compiler, mais j'ai l'erreur suivante :

/usr//bin/ld: cannot find -lm
collect2: ld returned 1 exit status
make[1]: *** [qemu-fast] Erreur 1
make[1]: Leaving directory `/home/user/Desktop/qemu/cvs/qemu/i386'
make: *** [all] Erreur 1

Comment corriger cela ? (Je suis très très ignorant en compilation, et ne
fais pour l'instant qu'appliquer les commandes préconisées )

Merci beaucoup.

Olivier Viennet
