I'm running QT Creator 2.0.1 and I'm having compiling problems.
I have a .cpp file with the line...

#include <QTcpSocket>

If I compile the .cpp it fails with ...

error: QTcpSocket: No such file or directory

BUT if I hover the mouse cursor over that #include line it comes up with the full path for the file, i.e. /usr/local/Trolltech/Qt-4.7.1/include/QtNetwork/QTcpSocket, and the file does exist with that full name.

So my question is why does it say the file does not exist when it builds whereas in editor mode it knows the file exists, and probably more importantly to me what can I do to fix it ?

#include <QTcpSocket> :

Better instead try #include <QtNetwork/QTcpSocket>

(You have /usr/include/ in the search path, not /usr/include/QtNetwork/).

Fedora ?
Please have a look at your installed 'qt-devel' :
rpm -ql qt-devel > qt-filelist.txt
The text file is saved in /home/<name>/.
Most handy that way : qt-filelist.txt = 3488 lines ( Fedora 13.)


With your custom install :
/usr/local/Trolltech/Qt-4.7.1/include/((QtNetwork))
.. then /usr/local/Trolltech/Qt-4.7.1/include/ is in the search path ? ?
If so : #include <QtNetwork/QTcpSocket> : will do.

Tried that it still doesn't find the file when I compile.

How do I set the search path ? Is it an environment variable or is it something else ?

You can try with a new line added to /etc/ld.so.conf :

/usr/local/Trolltech/Qt-4.7.1/lib

..

Thanks. that works a treat.

Happy Xmas
