Bonjour,
je travaille avec QT et Coin3d (Inventor) sous linux et j'essaye de faire une application qui reuni les deux,et enfait je compile les deux en ligne de commande en utilsant g++
quand je compile ce code QT :
1

|
QApplication app(argc,argv);
QPushButton quit("Quit");
quit.resize(75,30);
quit.setFont(QFont("Times",18,QFont::Bold));
QObject :: connect(&quit,SIGNAL(cliked()),&app,SLOT(quit()));
quit.show();
return app.exec(); |
j'utilise la ligne de commande suivante :
g++ -g -o test -I /usr/lib64/qt4/include -L /usr/lib64/qt4/lib64 -lQtGui test.cc
et ca marche parfaitement,
quand je compile le code Coin suivant :

avec la ligne :
g++ -o test -I /usr/lib64/qt4/include/ -I /usr/lib64/qt4/include/Qt/ -I /usr/include/Coin2/ -L /usr/lib/Coin2/ test.cc -lCoin -lSoQt
ca marche aussi parfaitement..

avec la ligne :
g++ -o tes -I /usr/lib64/qt4/include/ -I /usr/lib64/qt4/include/Qt/ -I /usr/include/Coin2/ -L /usr/lib/Coin2/ -L /usr/lib64/qt4/lib64/ test.cc -lCoin -lSoQt -lQtGui
il me sort "incident de segmentation"
et j'ai essayé de cerner un peu le problem,il vient apparement de -lQtGui,mais je dois l'inculre sinon l'edition de liens ne se passera pas bien..
quelqu'un pourrait m'aider la dessus ?
