I wanted to compile the Spot-On Encryption Suite from a qmake terminal with these commands and steps:

As compiling the Spot-On Encryption Suite requires several steps, including setting up the necessary dependencies as obtaining the source code, and then building the application with qmake, I tried these following steps to compile the the messenger – but probably the usage of the .pro file is much easier – Don’t see what is missing here:

Starting with the prerequisites

1. Operating System: Typically, this process is performed on a Unix-like system (Linux, macOS).

2. Dependencies: You will need the following dependencies installed on your system:
   o gcc (GNU Compiler Collection) or another C++ compiler
   o Qt (usually version 5 or later)
   o OpenSSL (for cryptographic operations)
   o qmake (part of Qt)

Steps to Compile Spot-On Encryption Suite

1. Install Dependencies:

o On a Debian-based system (like Ubuntu), you can install the necessary packages with:
sh
Code kopieren
sudo apt-get update
sudo apt-get install build-essential qt5-default libssl-dev

o On Fedora:
sh

Code kopieren
sudo dnf groupinstall “Development Tools”
sudo dnf install qt5-qtbase-devel openssl-devel

o On macOS, you can use Homebrew:
sh
Code kopieren
brew install qt openssl

2. Download Spot-On Source Code:
   o Typically, the source code is hosted on a version control system like GitHub. You can clone the repository using git.
   sh
   Code kopieren
   git clone https://github.com/textbrowser/spot-on.git

3. Navigate to the Source Directory:
   sh
   Code kopieren
   cd spot-on

4. Configure the Build:
   o Use qmake to generate the Makefile. Ensure that the qmake binary from your Qt installation is in your PATH.
   sh
   Code kopieren
   qmake spot-on.pro

5. Compile the Application:
   o Once the Makefile is generated, compile the application using make.
   sh
   Code kopieren
   make

6. Run the Application:
   o If the compilation is successful, you should have an executable file (usually named spot-on). You can run it with:
   sh
   Code kopieren
   ./spot-on

Troubleshooting which has been checked:
• Path Issues: Ensure that your qmake and compiler binaries are in your PATH. You might need to specify the full path to qmake if it’s not found:
sh
Code kopieren
/path/to/qt/bin/qmake spot-on.pro

• Qt Version: Ensure you are using a compatible version of Qt. If you have multiple versions installed, ensure you are using the correct one by specifying its path.

• Library Linking: Sometimes, you may encounter issues with linking libraries like OpenSSL. Ensure the libraries are correctly installed and the paths are properly set.
Example Script

Here’s a simple bash script to automate the above steps on a Debian-based system:
sh
Code kopieren
#!/bin/bash

Install dependencies

sudo apt-get update
sudo apt-get install -y build-essential qt5-default libssl-dev git

Clone the repository

git clone https://github.com/textbrowser/spot-on.git
cd spot-on

Configure the build

qmake spot-on.pro

Compile the application

make

Run the application

./spot-on

This script above should set up the environment, download the source code, and build the Spot-On Encryption Suite. Adjusting the commands based on my specific system configuration and package manager does not lead to a binary as the .pro file does:
