Question 1

How do I build DelphiZeroMQ for Android or iOS?

Accepted Answer

The README notes that building for iOS and Android is complicated and provides pre-built binaries; for custom builds, you need to download ZeroMQ and libSodium sources, use platform-specific scripts, and manage linking in Delphi projects, which can be error-prone.

Question 2

DelphiZeroMQ vs Indy sockets for Delphi networking?

Accepted Answer

DelphiZeroMQ is better for scalable, distributed messaging with patterns like pub-sub and load balancing, while Indy sockets are suited for traditional TCP/IP communication. ZeroMQ abstracts connection management and supports various transports, but requires more setup.

Question 3

Can I use DelphiZeroMQ with web applications or browsers?

Accepted Answer

No, it's designed for native Delphi apps on Windows, Linux, iOS, and Android; for web integration, you'd need a bridge service since ZeroMQ doesn't natively support browsers, unlike WebSockets or HTTP-based solutions.

Question 4

What are the performance benchmarks for PascalZMQ compared to CZMQ?

Accepted Answer

Specific benchmarks aren't provided, but PascalZMQ adds a Delphi object layer that may introduce slight overhead, though it optimizes for ease of use and integrates Protocol Buffers for efficient data handling, making it suitable for high-performance scenarios in Delphi environments.

Question 5

How to add encryption with libSodium in DelphiZeroMQ?

Accepted Answer

Enable encryption by setting the Broker's Bind parameter to use CURVE security (e.g., Broker.Bind('tcp://*:1234', TZSocketType.Router, True)) and linking libSodium libraries; the README briefly covers certificate handling but assumes familiarity with ZeroMQ's security model.

Question 6

Is there support for newer Delphi versions or FireMonkey?

Accepted Answer

The project targets Delphi 10.2 Tokyo and later for cross-platform support; it should work with FireMonkey for UI, but core messaging is platform-agnostic—check the GitHub repository for updates on compatibility with recent Delphi releases.
