mocs | My Own Car System , a Go & Qt application for your car

I am building my project on 2 different PCs, both using the same methods (Visual Studio 2017 with CMake). They both configure and generate fine using CMake. The issue is when I try to build them, one builds fine and the other has errors.

I have isolated the cause of this error and it seems to be whenever I try to instantiate either QLineSeries or QChart. There are NO red squiggles underneath my code. It all looks fine, until I try to instantiate either and then those errors appear.

I use QLineSeries a lot (I have 3 series), and I slowly commented out code until I found the culprit. The first line, me trying to create lineRedSeries = new QLineSeries; results in the errors below. Also, even if I comment out everything and try to create QChart *chart = new QChart();, it also causes the same errors.

Curiously enough, just declaring QLineSeries and QChartView in my h file doesn't cause this issue (so if I comment out the code in my cpp file). It's only when I try to create a QLineSeries or QChart that the errors occur.

I have removed a lot of unnecessary functions that are not pertinent for this question as my cpp file is quite long.

In my main.h:

The reason why I made the change is because I needed to use QtWidgets. I've been trying to build the project however I keep getting the following errors:

i'm decided to build some calculator with CMake, but it failed for some reason, yet it looks correct. I got a set(CMAKE_AUTOMOC ON) rule and yet, what is vtable? I can't simply build it... There are all project files below

I was following an introductory tutorial for using the KDE Framework and ran into problems when compiling. The code is the same as in the tutorial. The compiler outputs:

fatal error: KXmlGuiWindow: No such file or directory

My first thought was that I am simply missing a package so I used apt-cache search to search for kxml and installed libkf5xmlgui-dev. Despite that the error persists. I could not references to this error anywhere online. Has the import path been changed? Is another package required?

I am running Kubuntu 20.04.

I previously had to install other packages for compiling the "Hello World" program that did not yet include KXmlGuiWindow, but when I had installed them everything worked fine.

Edit: find /usr -name KXmlGuiWindow gave me the output /usr/include/KF5/KXmlGui/KXmlGuiWindow. I use Atom for my code editor so I compile the program from a terminal by running the commands given in the tutorial which is cmake .. && make (from a build directory in the project's root directory).

The full output pf that command is

I need to be able to call my c++ function from qml(javascript). But I seem to get an error when trying to register the class as a qml type by using qmlRegisterType

I use cmake CMakeLists.txt to build my project. I'm not using qt-creator.

main.cpp

I am having an issue with CMake and a simple QT example. I am updating my CMake configuration to follow the modern way of doing it, meaning supporting CMake > v3.0.

Here is my CMakeLists.txt
