[Qt-creator] Latest git creator branches require up-to-date Qt
Hi, it happened once more: An API change in the QtDeclarative module required some changes in QuickDesigner creator. A fix has been pushed to the 2.0 branch already, and will soon be integrated back to master. This means that as soon as you pull the master or 2.0 branch from creator, you've to also pull/compile a new Qt from qt.git/4.7 branch, and vice versa. You can also revert the commits inside creator locally: git revert -n b2cb2f6e git revert -n f0cb98463 Or you just disable the qmldesigner plugin in src/plugins/plugins.pro :) Kai -- Kai Koehne Software Engineer Nokia, Qt Development Frameworks Nokia gate5 GmbH Firmensitz: Invalidenstr. 117, 10115 Berlin, Germany Registergericht: Amtsgericht Charlottenburg, Berlin: HRB 106443 B Umsatzsteueridentifikationsnummer: DE 812 845 193 Geschäftsführer: Dr. Michael Halbherr, Karim Tähtivuori ___ Qt-creator mailing list Qt-creator@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-creator
[Qt-creator] Problems building with Qt Creator
Hi all,
I'm doing a simple login dialog and since I tried to use QTcpSockets
I've been having some problems building my project.
I receive these errors:
logindialog.obj:: error: unresolved external symbol
__declspec(dllimport) public: virtual __thiscall
QTcpSocket::~QTcpSocket(void) (__imp_??1QTcpSocket@@u...@xz) referenced
in function public: virtual __thiscall
LoginDialog::~LoginDialog(void) (??1LoginDialog@@u...@xz)
logindialog.obj:: error: unresolved external symbol
__declspec(dllimport) public: __thiscall QTcpSocket::QTcpSocket(class
QObject *) (__imp_??0QTcpSocket@@q...@pavqobject@@@Z) referenced in
function public: __thiscall LoginDialog::LoginDialog(class QWidget *)
(??0LoginDialog@@q...@pavqwidget@@@Z)
debug\Backoffice.exe:: error: 2 unresolved externals
I'm using Qt Creator in Windows XP 32 bits. From what I found online,
similar problems were solved by reinstalling Qt, adding settings to the
.obj file, disabling shadow building in the pro.user file... I tried
the last two solutions, none worked. The best I got was no errors but
the building stopped and consequently was not completed.
Anyone know how to solve this. If anyone knows, please sahre it with
me, because my work is getting delayed :| I will include the project
files as attachments, since it's only a login dialog and there's only a
few lines of code on it.
Thanks in advance,
João

Re: [Qt-creator] Problems building with Qt Creator
Hi João! Please be aware that this mailing list is about developing Qt creator (not developing with Qt Creator:-). It would be appreciated, if you were to direct more generic Qt-related questions to the qt-interst mailing list instead.

From what I found online, similar problems were solved by reinstalling Qt, adding settings to the .obj file, disabling shadow building in the pro.user file... Don't trust the internet: Those suggestions are just voodoo and do not help with the issue:-) Try changing QT += core gui to QT += core gui network in your .pro file instead.

The symbols are not found because you are not linking in Qt's network libraries, which contain QTcpSocket. Add QT += network to your project file.

Re: [Qt-creator] Problems building with Qt Creator
Actually this would have failed if you had been building without Qt Creator as well. Your project isn't linking to QtNetwork because you need to add network to the QT += line. /s/ Adam On Tue, Jul 13, 2010 at 7:05 AM, j...@student.dei.uc.pt wrote: Hi all, I'm doing a simple login dialog and since I tried to use QTcpSockets I've been having some problems building my project.

So, many thanks for all the quick (and useful) answers! :] And most important, I solved (and understood) the problem. Tobias, I really thought this list was the right one for these issues, next time I'll check qt-inte...@trolltech.com (I don't even knew that existed).
