Problème de compilation de kqemu

[Poulpatine]

Salut @ tous :)

Voilà, en cours pour faire des tests j'utilise qemu, le problème c'est que c'est relativement lent ... Je me suis donc mis en tête de compiler le module d'accélération pour qemu : kqemu mais je n'arrive pas à le compiler. J'ai lu qu'il était incompatible avec gcc 4.0 alors j'ai fait un pti :

export CC="gcc-3.4" et export CXX="gcc-3.4" mais toujours la même erreur.

Voici la sortie

Voilà, donc si vous pouviez m'aider ça serait cool

Merci :)

depuisquand les sources de kqemu sont dispo ?

c'est nouveau ?

[semionsi]

bah enfait ya un bout a compiler. Sinon c'est pas plutot ln -s /usr/bin/cc /usr/bin/gcc-3.4 ?

Aucune idée, mais je l'ai toujours vu comme ça ( en même temps toujours ça fait pas beaucoup dans ce cas ;-) )

tu voulais pas dire plutot ln -s /usr/bin/gcc-3.4 /usr/bin/cc ?

( ça ne résoud pas le problème ) j'ai aussi testé ln -s /usr/bin/gcc-3.4 /usr/bin/gcc :(

Bon, alors finalement j'ai réussi à compiler le truc :)

Pour info, il fallait installer la zlib1g-dev puis effectivement faire un lien : ln -s /usr/bin/gcc-3.4 /usr/bin/gcc :)

Mais bon, petit soucis, mon noyau a été compilé avec gcc 4 alors que j'ai compilé le module avec gcc 3.4 du coup il ne se charge pas, j'aurais du m'en douter :)

Je vous tiens au courant des mes aventures. :)

block-qcow.c:26:18: error: zlib.h: Aucun fichier ou répertoire de ce type

Voilà...

[semionsi]

Xcuse moi pour le ln -s inversé

[Poulpatine]

Pas de soucis :)

Pour la suite de l'histoire :

j'ai réussi à compiler le module mais mon noyau étant compilé en gcc 4 et le module en gcc 3.4 ce dernier refusait de se charger. J'ai donc recompilé mon noyau en gcc 3.4.

Mais finalement, qemu déconne et je n'arrive pas à installer correctement une debian.
