(VS2010,vista,Qt) "unresolved external symbol " à la compilation
salut,
je teste actuellement VS 2010, et je voudrais faire un petit projet d' exemple:
Code:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
| #include <QtGui/QApplication>
#include <QtGui/QPushButton>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QPushButton bouton("Quitter");
bouton.show();
QObject::connect(&bouton, SIGNAL(clicked()), &app, SLOT(quit()));
return app.exec();
} |
je précise que j'ai compilé la partie debug de Qt (mais bien?), et que je suis sous windows vista.
j'ai ajouté dans les propriétés du projet (qui est du type "empty project" sous VS) les chemins
include => c:/Qt/4.5.1/include
exe => c:/Qt/4.5.1/bin
lib => c:/Qt/4.5.1/lib
j'ai bien l'autocompletion dans le projet (super avec la prise en charge de Qt), mais au moment de compiler j'ai l'erreur suivante :

je ne suis pas sûr que la compil se soit bien passée; répondez-moi même si vous pensez que l'erreur vient de là, je porterai plus d'attention à cela alors.
