[ubuntu-it] a proposito di qemu

Sab 22 Ott 2005 12:49:46 UTC

Ciao a tutti, in questi giorni sta facendo delle prove con qemu, il
software di emulazione di processore. Ho installato il pacchetto,
tutto bene, ma è lento. Allora ho provato a compilare dai sorgenti con
l'acceleratore (kqemu), ma dopo aver dato ./configure (che sembra
funzioni), il make mi da questo risultato:
