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

[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:

Undefined symbols for architecture x86_64:
  "bool QTest::qCompare<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >, char [11]>(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, char const (&) [11], char const*, char const*, char const*, int)", referenced from:

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
#
#-------------------------------------------------

QT       += testlib

QT       -= gui

TARGET = test_user
CONFIG   += console
CONFIG   -= app_bundle

TEMPLATE = app

# The following define makes your compiler emit warnings if you use
# any feature of Qt which as 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 += \
        test_user.cc \ 
    test_group.cc \
    contact.cpp \
    user.cpp \
    group.cpp

DEFINES += SRCDIR=\\\"$$PWD/\\\"

INCLUDEPATH += ../QTConsoleApp

stdlib -=libc++
stdlib -=libstdc++

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

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 \
    ..\QTConsoleApp\group.cpp

[Dhara]

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

[Dhara]

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

[jsulm]

@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

[jsulm]

@Dhara Are there any other errors like library not found?

[Dhara]

@jsulm No, i dont see any such error, i have QtTest and also Qtest included also

[jsulm]

@Dhara Can you post the whole build log?

[Dhara]

[SGaist]

Try removing CONFIG += c++11 (it is now enabled by default since Qt 5.7) and do a full re-build.

[Dhara]

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

CONFIG += c++11

I removed the same and built the whole project after a clean but i still face the same issue. Is it necessary that my cpp files should extend QObject ?

[jsulm]

@Dhara I don't know whether it is related, but why do you have these lines in your pro file:

stdlib -=libc++
stdlib -=libstdc++

You should try a simple project with unit tests to be sure it is working in general.

[Dhara]

@jsulm @SGaist The issue was with diff arguments being passed. I cannot modify the test case which passes char * to QCOMPARE, but i dont know how to make a char * value be returned from a function using a string*, in other words i would like to convert string * to char * and without the const issues. How should i do that ?

[jsulm]

@Dhara you could do

QCOMPARE(u.uri(), string());

then you compare two strings

[Dhara]

@jsulm Yes, but this would touch the unit test, i have been given conditions not to change the unit test.
