ops, he did those error because I put this kine before the include,
I put them after and the error of before came back,
he write me:
undefined reference to `QString::shared_null'
[/usr/lib/qt3/include/qstring.h]
undefined reference to `QStringData::deleteSelf()'
[/usr/lib/qt3/include/qstring.h]
undefined reference to `QApplication::QApplication(int&, char**)'
main.cpp
undefined reference to `QString::QString(char const*)' main.cpp
.
.
.
someone, undestand way? what shold I do to compile it in eclipse?
