Building Havoc QT Client on Ubuntu 20.04 codespace

[zrayburn]

Build Context
I was attempting to build the Havoc Client in a GitHub Codespace which is based on Ubuntu 20.04.
Docker image the Codespace is based on: mcr.microsoft.com/devcontainers/universal:2
VERSION="20.04.5 LTS (Focal Fossa)"
This build was attempted on commit ID 8418a43.
Steps

1. Spin up Codespace dev environment
2. Follow pre-requisite installation

Pre-requisites

sudo apt install -y git build-essential apt-utils cmake libfontconfig1 libglu1-mesa-dev libgtest-dev libspdlog-dev libboost-all-dev libncurses5-dev libgdbm-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev libbz2-dev mesa-common-dev qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools libqt5websockets5 libqt5websockets5-dev qtdeclarative5-dev golang-go qtbase5-dev libqt5websockets5-dev libspdlog-dev python3-dev libboost-all-dev mingw-w64 nasm

Ubuntu 20.04 / 22.04

You must enable Python 3.10 in your APT repositories before you can run the Client successfully.

sudo apt install build-essential
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.10 python3.10-dev

3. Follow Build and Run

Build and Run:

cd Havoc/Client
mkdir Build
cd Build
cmake ..
cd ..
./Havoc.sh

4. Error generated during build

5. Fix in my environment
   In Client/Include/global.hpp add #include <QTime> at the top of the file.

Discussion
Most likely this is just the Codespace docker container not using the same QT headers as a full normal Ubuntu install. Would it be detrimental to include QTime explicitly instead of relying upon the OS to implicitly include it?
I haven't tested on a full ubuntu VM yet but I assume that builds fine.

Noticed this same issue in the wiki, just didn't see it before publishing this issue. Solution is to install a newer version of QT backported to ubuntu 20.04. Trying build process on 22.04 to see if it needs to be qt6 across the board.

[zrayburn]

Yes this is exclusively a 20.04 issue with it's specific version of qt5. Could update the global.hpp or maybe just include a separate build step for 20.04.

Came here for the same reason. Got the error while compiling in Ubuntu 20.04 and had to #include <QTime> in /Client/Source/UserInterface/Widgets/DemonInteracted.cpp for it to work.

As @js-virtualretail seems to have solved it, I will close this issue. Ive mentioned it in the WIKI and requested a merge in #139.
