I'm attempting to get Qt setup to run a simple hello world example, but I can't get the compilation setup right for the IDE (QtCreator). When I attempt to build by pressing the build button, I am getting the following error message:
Qt creator needs a compiler setup to build. Configure a compiler in the kit options
So I noticed that I had nothing setup for the compiler. I then downloaded a MinGW compiler and it seems the IDE managed to recognize it automatically. Still, when I attempt to build I am getting the same error message.
The truth is that I really don't know the process of compilation either from the command line or in other IDEs. I've read that there might be an issue with paths? I'm running on Windows. I would be extremely grateful if someone could explain what I may be doing wrong and what issue I may be having with building in QtCreator.
You will need to do the following steps for QtCreator:
1) Go to Settings > Build and Run > Kits.
2) Check if the auto-detection is correct. It is probably not if you have issues, so you will need to either set up manually or rreinstall QtCreator to see if the problem goes away. If it is not detected, you will have a read exclamation mark.
3) Add a new Kit.
4) Type a name.
5) You need to choose the proper "Qt version".
6) You need to choose the compiler.
7) Select the "Make Default" option.
As for command line, you should be able to do something like this to build a simple dummy main.cpp:
main.cpp
int main() {}
and then you can run the following commands in the (msys/cygwin/etc) prompt:
qmake -project && qmake && make

I was programming in C++ a small program using QMultiMedia and QAudioOutput.
I compile and run my program in Qt (6.4) without error however when I run my program in File Explorer, when all DLLs are present, I get this error:
'could not load multimedia backend'"
QtMultimedia is not currently supported on this platform or compiler.'
So I started my research and I found several solutions however I did not understand their explanations very well (I start ...).
Here are the links I found:
-> Qt forum
-> Bugreports
-> CSDN
I tried to copy all the DLLs in mingw/bin in my folder or there is my .exe, I also copied the multimedia plugin (from mingw/plugins) to my folder or there is my .exe.
I'm on Windows 10 22h2.
Could you give me a clearer explanation? I would be very grateful.
Kind regards
Albin

I am using vs code to write my C++ code now. However, I don't know how to set up a C++ linter for my vs code environment. I find one called C++ advanced lint but its setting seems a little complicated and I spend a lot of time but still didn't get success. Want to ask someone who also using vs code to write c++ that which c++ linter do you use? and how to use it? Thanks.
I am using clang-tidy on ubuntu. First of all download it from package manager:
sudo apt-get install clang-tidy
Then install the clang-tidy extension in vscode (Clang-Tidy
notskm.clang-tidy).
Once installed click on the extension settings
Locate Clang-tidy: Checks, click on Edit in settings.json.
In your settings.json file will be generated this code:
"clang-tidy.checks": [
]
You can paste here the checks that you want to enable.
To see the available checks you can run this command from terminal:
clang-tidy --list-checks -checks='*'
For example you could take all the modernize checks, and you would end up with something like this:
"clang-tidy.checks": [
"modernize-*"
]
Save your settings.json and go to your code. When saving a file the linter should now tell you what are the problems in your code.

So I've attempted to install the aircrack-ng library on my Mac. I've followed the instructions outlined by the aircrack-ng docs and by the README file on the Github repository. When I run,
aircrack-ng --help
I get the list of options, etc... like I should. But when I run,
airmon-ng
I get
zsh: command not found: airmon-ng
I've run both commands as root and in the aircrack-ng directory. I've tried installing both the stable version linked by the aircrack-ng docs and the version directly from Github. Other commands like airebase-ng and aircrack-ng work (at least they result in output), but for some reason airmon-ng doesn't. Also, inside the aircrack-ng directory, I found scripts named "aircrack-ng", "airbase-ing", etc... but there weren't any files named "airmon-ng." The commands I used in the setup were:
git clone https://github.com/aircrack-ng/aircrack-ng
cd aircrack-ng
autoreconf -i
./configure --with-experimental
I tried it once with
make
make install
and then repeated the whole process again and tried using
gmake
and both times I get the same error. I'm incredibly confused why airmon-ng appears to be missing. Any help is appreciated :) Thanks.
My bad, I finally found the answer in a similar StackOverflow question that actually got recommended to me since I asked this question.
The reality is that there is no airmon-ng command on the MacOS installation; I was looking for something that didn't exist. On MacOS, there's an alternative command called airport (that's built into the OS) that you can use instead.

Complete noob right here, I'm learning c++ and I saw some tutorial somewhere with instructions to compile the Qt application example from the command line, then I noticed the path from the tutorial was not correct, I want to learn how to compile Qt from command line, and maybe even do some makefiles to automate the process, at least I want to get started ...It seems like the qt libraries are already installed within my system since it is using the KDE desktop environment, but I don't know how should I link or what paths should I include as arguments. Please guide me, remember I'm a complety noob but I really want to learn.
This is the tutorial I'm talking about http://zetcode.com/gui/qt5/introduction/
When you build, Qt Creator does three things only: it invokes qmake, then make, then runs the target. That's all.
Suppose your project is in ~/src/project. Here's how you would build it properly using a shadow build folder:
$ mkdir -p ~/src/project-build
$ cd ~/src/project-build
$ qmake ~/src/project
$ make -j

How do I generate a .sys file so that I can load it in the OSRloader?
A .sys file is basically a .dll file that only depends on the kernel.
You'll need the Windows Driver Kit's libraries (especially ntoskrnl.lib).
Open up the project properties and:
Select Linker->Input, then change Ignore All Default Libraries to Yes.
Select Linker->Input, then add ntoskrnl.lib to Additional Dependencies.
Select Linker->System, then change Driver to to Driver, and Subsystem to Native.
Select Linker->Advanced, then change Entry Point to DriverEntry.
Select Linker->Advanced, then change Image Has Safe Exception Handlers to No (if it's there).
Do these for both Debug and Release configurations (you might not be able to use the Debug build).
Then build. You may also need to add other libraries (e.g. BufferOverflowK.lib).
