symbol(s) not found for architecture x86_64

CN_Cabbage

Hi, I met the same problem with this, Re: symbol(s) not found for architecture x86_64

I have made the suggestions in that post but it didn't solve my question. I new a post according to the Qt Forum suggestion.
I'm on macOS Catalina 10.15.6, Qt version: Qt 5.12.0.
My kits:

My sqldrivers folder

@CN_Cabbage Please show what symbols are not found.
The libs are probably not for x86_64 but ARM, or they are simply not found (post the content of your pro file).

@jsulm
Sorry jsulm, I'm very new to Qt, and I don't know how to show what symbols are not found.

Below is my .pro file

QT       += core gui sql

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = bili_tedu_stu_score_mgn
TEMPLATE = app

# 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

CONFIG += c++11

SOURCES += \
        main.cpp \
        dialog.cpp

HEADERS += \
        dialog.h

FORMS += \
        dialog.ui

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

By the way, when I choose compiler to arm64, an error arises.

@CN_Cabbage said in symbol(s) not found for architecture x86_64:

and I don't know how to show what symbols are not found

It is just above what you already posted (in "Issues" panel)...

@jsulm Hi jsulm, appreciate for ur help. But there is Nothing above "Issues" panel. Edit panel is above the Issues panel.

It turns out I forgot to implement the function in .cpp file that declared in .h file.
