:-1: error: symbol(s) not found for architecture x86_64

[Dhara]

Hi

I am quite new to QT. I have created a subdirs project that has the main app part and also test unit project in it. However when i build the whole project i get errors of the kinds below:

Undefined symbols for architecture x86_64:
  "user::setStatus(user::Status)", referenced from:
      TestUser::cannotSetNullUserStatus() in test_user.o
      TestUser::canChangeUserStatusToOffline() in test_user.o

      TestUser::copyOfUserSharesStatus1() in test_user.o
      TestUser::copyOfUserSharedStatus2() in test_user.o
  "user::operator=(user const&)", referenced from:
      void std::__1::list<user, std::__1::allocator<user> >::assign<user const*>(user const*, user const*, std::__1::enable_if<__is_input_iterator<user const*>::value, void>::type*) in test_group.o

      TestGroup::contactFromGroupSharesName1() in test_group.o
      TestGroup::contactFromGroupSharesName2() in test_group.o```

Can anyone please guide me where i am wrong? I can share in the cpp code file too:

user::Status& user::setStatus(user::Status status) {
if (!isNull()) {
userStatus = new user::Status;
*userStatus = status;
}
return *userStatus;
}

The header file has this method declaration too. I need to somehow finish this soon, and i tried googling but i dont understand what i should do.

Please help.

Hi and welcome to devnet,

What version of Qt are you using ?
On what platform ?
With which compiler ?

[Dhara]

@SGaist Hi,

QT 5.9, Qmake compiler and macOS.

[jsulm]

@Dhara Did you add the cpp file containing method definitions of the user class?
It looks like you're writing unit tests?
Can you show your pro file?

[Dhara]

@jsulm :

so i have the main project that has the following contents:

TEMPLATE = subdirs

SUBDIRS += \
    Test \
    QTConsoleApp

Test.depends = QTConsoleApp

The QTConsoleApp has the following pro file:

QT += core
QT -= gui

CONFIG += c++11

TARGET = QTConsoleApp
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = lib

SOURCES += main.cpp \
    contact.cpp \
    user.cpp \
    group.cpp

# The following define makes your compiler emit warnings if you use
# any feature of Qt which as been marked 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

DEFINES += QTCONSOLEAPP_LIBRARY

# 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

HEADERS += \
    contact.h \
    user.h \
    group.h

The last one has the following pro content:

#-------------------------------------------------
#
# Project created by QtCreator 2017-06-18T23:06:36
#

QT       += testlib

Thanks

@Dhara said in :-1: error: symbol(s) not found for architecture x86_64:

TEMPLATE = lib

why is you console app a lib?

[Dhara]

@jsulm : i want to access user.h in the Test project, and to include it into the path i thought the QTConsoleApp should be a lib that is why. Should i change it to app? And check?

[jsulm]

@Dhara The question is actually: should it be an executable or a lib? So, do you want to execute QTConsoleApp? Because you cannot execute a library.
It doesn't have to be a lib to be able to access its source file from Test project. You can just add needed source files in the pro file of your Test project.

[Dhara]

@jsulm : i actually want to run the test project and see if the test cases pass or fail. I however changed it to app too :D.. but i get the same error . I am unfortunately knew to C++ and qT too so i wasn't even aware what i should pick so i think either one should be ok : exe types or even lib.

[jsulm]

@Dhara Just add the source files you want to test to your Test project (in the pro file).

[Dhara]

@jsulm okay. I will do that and get back to you .

[Dhara]

@jsulm : I updated the code and i get the same kind of error but i think its reduced a little bit:

      ...

i have not pasted the other errors, but are of similar kinds.

[jsulm]

@Dhara What exactly did you update? It looks like QTest::qCompare is not found. Do you have QT += testlib in the pro file in your Test project?

[Dhara]

@jsulm I moved the files from qTConsoleApp to the Test project. So now i just have 2 pro files. The main one and the Test Project one's.

main pro:

TEMPLATE = subdirs

SUBDIRS += \
    Test

Test project's pro:

#-------------------------------------------------
#
# Project created by QtCreator 2017-06-18T23:06:36

Yes,, it does have the line you wrote.

@Dhara said in :-1: error: symbol(s) not found for architecture x86_64:

I moved the files from qTConsoleApp to the Test project

Why?! They belong to qTConsoleApp, not to the test project! Don't move them, just reference them in Test pro file:

SOURCES += \
        test_user.cc \ 
    test_group.cc \
    ..\QTConsoleApp\contact.cpp \
    ..\QTConsoleApp\user.cpp \

[Dhara]

@jsulm okay . sorry about it. i will revert it back.

@jsulm , i have got the files back and added the sources too, the error message i get is :

@Dhara Can you show how you're using QCOMPARE?

[Dhara]

@jsulm :

void nullUserUriIsEmpty() {
        user u;
        QCOMPARE(u.uri(), "");
    }

The method u.uri() is as under:

string contact::uri() { return *contactUri; } // inside the cpp file

string uri(); // inside the h file
