How do you get it running?

Difficulty · hard Time to first run · 1day+

Requires locating and installing very specific legacy build tools like Qt 5.6.3, Visual Studio 2015, and Xcode 8.3, which may conflict with modern development environments.

The license terms are not clearly stated in the repository explanation, so it is unclear what permissions apply to using or modifying this code.

In plain English

MEGAsync is the official desktop application that keeps files on your computer automatically synced with your MEGA cloud storage account. If you use MEGA to store files online, this tool makes sure that whenever you add, edit, or delete a file on your computer, the same change happens in your cloud storage, and vice versa. It works on Windows, macOS, and Linux. This repository contains the full development source code for the desktop app. Under the hood, it is built using the Qt framework, a popular toolkit for creating applications that run across multiple operating systems. The codebase also relies on a variety of third-party libraries for handling things like cryptography, media information, and network requests to communicate securely with MEGA's servers. The audience for this project is primarily developers and system administrators who want to compile the app themselves rather than downloading the standard installer from MEGA's website. For example, a Linux user running a specific distribution might need to build the application from source to ensure compatibility with their system. The instructions cover the specific tools, compilers, and third-party files needed to successfully build the app on each supported operating system. The README focuses almost entirely on the steps required to compile the software from source, detailing very specific build environments like Visual Studio 2015 and Qt 5.6.3 for Windows. It does not go into detail about how the actual syncing mechanism works, what the user interface looks like, or how to configure the application once it is running. It is strictly a guide for building the software from scratch. One notable tradeoff is the heavy reliance on very specific, older development tools. For instance, the build instructions call for Xcode 8.3 and Qt 5.6.3, which are several years old. This means that anyone attempting to compile the application today might face compatibility challenges if they are running modern development environments, requiring them to seek out and install these legacy tools to build the project successfully.

Copy-paste prompts

Prompt 1

Help me set up the build environment to compile MEGAsync from source on Linux, including installing Qt 5.6.3 and required third-party libraries.

Prompt 2

I need to build MEGAsync on macOS but my system has a newer version of Xcode. Walk me through installing Xcode 8.3 and Qt 5.6.3 side by side with my current tools.

Prompt 3

What are the specific third-party dependencies I need to download and where do I place them to successfully compile MEGAsync on Windows with Visual Studio 2015?

Prompt 4

Generate a checklist of all build prerequisites for compiling MEGAsync from source, organized by operating system.
