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

[jsulm]

@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
#
#-------------------------------------------------

QT       += testlib

QT       -= gui

TARGET = test_user
CONFIG   += console
CONFIG   -= app_bundle

TEMPLATE = app

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]
