Cross compilation avec Qt

Bonjour,

J'aimerais pouvoir compiler une application Windows sous Ubuntu utilisant Qt.
J'ai, pour cela, suivi ce premier tuto : http://doc.qtfr.org/post/2007/04/10/Cross-Compilation-Native-dapplication-Qt-depuis-Linux

Lorsque je fais un make, j'ai l'erreur suivante :

tallotte@tallotte-laptop:~/Bureau/Qt/test$ qmake -project
tallotte@tallotte-laptop:~/Bureau/Qt/test$ qmake-qt4 -spec win32-x-g++

Apparemment, le compilateur ne trouve pas les fichiers header. Où sont-ils ? Que dois-je faire ?

J'ai ensuite suivi un autre tuto qui reprenait tout depuis le début : http://mtodorovic.developpez.com/linux/cross-compil-qt4/
Et là, j'ai une autre erreur :

Je vous remercie de votre aide.

Re : Cross compilation avec Qt

bonjour,
Tu as un problème à l'édition des liens, essayes de nettoyer en faisant "make clean" avant de faire "make"...

Re : Cross compilation avec Qt

Cela ne change rien, dans les deux cas, j'obtiens la même erreur.

Re : Cross compilation avec Qt

Petite précision, je veux bien sûr utiliser la version 4.5.2.
Dans les précédents posts, il ne faut donc pas lire 4.2.3 mais 4.5.2.
