Hi,
I just downloaded Codeblocks and tried my first QT4 program:
#include <QApplication>
#include <QPushButton>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QPushButton hello("Hello world!");
hello.resize(300, 130);
hello.show();
return app.exec();
}
But compilation stops with "QApplication: no such file". When I change to
#include <qapplication.h>
#include <QpushButton.h>
everything works fine.
Calling "make" from a DOS box works fine for both versions.
My project file looks like this (relevant extract):
<Compiler>
<Add directory="k:\qt_4.1.4\include"/>
<Add directory="k:\qt_4.1.4\include\Qt"/>
<Add directory="k:\qt_4.1.4\include\Qt\ActiveQt"/>

<Add directory="k:\qt_4.1.4\include\Qt\QtAssistant"/>

</Compiler>
<Linker>
<Add library="libQt3Support4.a"/>
<Add library="libQtAssistantClient.a"/>
<Add library="libQtCore4.a"/>
<Add library="libQtDesigner4.a"/>

<Add library="libQtOpenGl4.a"/>
<Add library="libQtSql4.a"/>
<Add library="libQtXml4.a"/>
<Add directory="k:\qt_4.1.4\lib"/>
</Linker>
Doesn't it look already:
In the directory "k:\qt_4.1.4\include\Qt\QtCore" there's "QApplication" with just one line "#include <qapplication.h>" to include the "real" header. And "qapplication.h" is in the same directory.
Can anybody explain to me why this strange behaviour happens and - more important - how to solve it.
