Hi All,
I have created a custom widget, e.i, a label with a clicked() signal. It is properly showing in Qt Designer and I was able to add it on my project UI. The problem is during the compilation of my project, the following error occurred:
release
/employeeentry.
o:employeeentry.
cpp:(.
text$_ZN16Ui_EmployeeEntry7setupUiEP7QDialog
[Ui_EmployeeEntry
::setupUi(QDialog*)]+0x3f1
): undefined reference to `_imp___ZN7HSLabelC1EP7QWidget
'
release/employeeentry.o:employeeentry.cpp:(.text$_ZN16Ui_EmployeeEntry7setupUiEP7QDialog[Ui_EmployeeEntry::setupUi(QDialog*)]+0x3f1): undefined reference to `_imp___ZN7HSLabelC1EP7QWidget'

Below are the codes of my custom label plugin:
