Posté(e) le 28 novembre 200519 a 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 bidule:/home/poulp/tmp/qemu-0.7.2# make gcc -Wall -O2 -g -fno-strict-aliasing -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -o dyngen dyngen.c dyngen.c: In function

Posté(e) le 28 novembre 200519 a Auteur depuisquand les sources de kqemu sont dispo ? c'est nouveau ? Aucune idée, mais je l'ai toujours vu comme ça ( en même temps toujours ça fait pas beaucoup dans ce cas ;-) ) bah enfait ya un bout a compiler. Sinon c'est pas plutot ln -s /usr/bin/cc /usr/bin/gcc-3.4 ? 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. :) Modifié le 28 novembre 200519 a par Poulpatine

Posté(e) le 30 novembre 200519 a Auteur 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.
