Bonjour,
J'essaye de me mettre � QT et j'ai un probl�me de compilation.
J'utilise RedHat 8.0
QT 3.0.5
[EMAIL PROTECTED] qt]$ cat main.cpp
#include <qapplication.h>
#include <qpushbutton.h>
int main( int argc, char **argv )
{
QApplication a( argc, argv );
QPushButton hello( "Hello world!", 0 );
hello.resize( 100, 30 );
a.setMainWidget( &hello );
hello.show();
return a.exec();
}
[EMAIL PROTECTED] qt]$ qmake -project
[EMAIL PROTECTED] qt]$ qmake
[EMAIL PROTECTED] qt]$ make
g++ -o qt main.o -L/usr/X11R6/lib -lXext -lX11 -lm
main.o: In function `main':
main.o(.text+0x30): undefined reference to
`QApplication::QApplication[in-charge](int&, char**)'

main.o(.text+0xd9): undefined reference to `QString::shared_null'
collect2: ld a retourn� 1 code d'�tat d'ex�cution
make: *** [qt] Erreur 1
Il semblerait (suite � des recherches sur google) qu'il me manque "-lqt" ou
"-lqt-mt" comme flag de compilation. J'ai essay� de les mettre mais ils
sont introuvables, alors que si je fais:
[EMAIL PROTECTED] qt]$ /sbin/ldconfig --print-cache | grep libqt
libqtmcop.so.1 (libc6) => /usr/lib/libqtmcop.so.1
libqthreads.so.0 (libc6) => /usr/lib/libqthreads.so.0
libqt.so.3.0.5 (libc6) => /usr/lib/qt-3.0.5/lib/libqt.so.3.0.5
libqt.so.3.0 (libc6) => /usr/lib/qt-3.0.5/lib/libqt.so.3.0
libqt.so.3 (libc6) => /usr/lib/qt-3.0.5/lib/libqt.so.3
libqt.so (libc6) => /usr/lib/qt-3.0.5/lib/libqt.so
libqt-mt.so.3.0 (libc6) => /usr/lib/qt-3.0.5/lib/libqt-mt.so.3.0
libqt-mt.so.3 (libc6) => /usr/lib/qt-3.0.5/lib/libqt-mt.so.3
libqt-mt.so (libc6) => /usr/lib/qt-3.0.5/lib/libqt-mt.so
ils semblent �tre la..
J'ai �galement:
[EMAIL PROTECTED] ysagon]$ echo $QTDIR
/usr/lib/qt3-gcc3.2
Voila, si quelqu'un � un d�but de piste, je serai tr�s content!
