[SOLVED]Errors while compiling

Paawan

Hi All,

I am getting many error when compiling and cannot understand what the cause:

udpchat.obj:-1: error: LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QLineEdit::QLineEdit(class QWidget *)" (_imp??0QLineEdit@@QEAA@PEAVQWidget@@@Z) referenced in function "public: __cdecl UDPChat::UDPChat(class QWidget *)" (??0UDPChat@@QEAA@PEAVQWidget@@@Z)

udpchat.obj:-1: error: LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QTextEdit::QTextEdit(class QWidget *)" (_imp??0QTextEdit@@QEAA@PEAVQWidget@@@Z) referenced in function "public: __cdecl UDPChat::UDPChat(class QWidget *)" (??0UDPChat@@QEAA@PEAVQWidget@@@Z)

There are about 40 errors like this.

Under each of them it states " File not found: udpchat.obj"

I have made a class udpchat class ( a sub-class of QWidget).

Please advice.

I have run QMake many times.

Hi,

Can you show your project pro file ?

Paawan

TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .

Input

SOURCES += main.cpp udpchat.cpp

QT += network

HEADERS += udpchat.h

SGaist

Are you using Qt 4 or Qt 5 ?

Also, you should give TARGET a value

Hi,

I am using Qt 5.

What value should I give TARGET?

Thanks

Hi,
Target is the name of your final executable . You should try this "tutorial":http://qt-project.org/doc/qt-4.8/qmake-tutorial.html

Qt5: You need to add "widgets" to the QT variable value (and rerun qmake) to have access to the QLineEdit, QtextEdit and other widgets

@ChrisW67: Yep. It now runs.

Thank you very much.
