Problem with class type for dll

[cleopa]

Hi All,

I have been trying to create a shared library using guidelines from the article https://doc.qt.io/qt-5/sharedlibrary.html :

Qt .pro :profile1.pro

QT       += qml quick core
 
 
TARGET = profile1
TEMPLATE = lib
 
DEFINES += PROFILE1_LIBRARY
 
# The following define makes your compiler emit warnings if you use
# any feature of Qt which has been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS
 
 
 
# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0
 
SOURCES += \
        profile1.cpp
 
HEADERS += \
        profile1.h \
        profile1_global.h 
 
unix {
    target.path = /usr/lib
    INSTALLS += target
}

QT       += qml quick core


TARGET = profile1
TEMPLATE = lib

DEFINES += PROFILE1_LIBRARY

# The following define makes your compiler emit warnings if you use
# any feature of Qt which has been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS



# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
        profile1.cpp

HEADERS += \
        profile1.h \
        profile1_global.h 

unix {
    target.path = /usr/lib
    INSTALLS += target
}

I keep getting an error for class declaration : class PROFILE1SHARED_EXPORT Profile1 -" variable has incomplete type 'class Q_DECL_EXPORT' "
Thank you in advance for your help.
