fszmq

An F# binding for the ZeroMQ distributed computing library.

fszmq is an MPLv2-licensed F# binding for the ZeroMQ distributed computing library. It provides a complete binding to versions 2.1.x, 3.2.x, 4.0.x, 4.1.x of ZeroMQ (Note: prior to 4.0.0, each binding is a separate branch in git, as there are some non-compatible differences). This library is primarily designed to be consumed from F#. However, where possible, the library has been designed to appear "friendly" when consumed by other CLR languages (C#, et aliam).


NuGet

The fszmq library can be installed from NuGet:

PM> Install-Package fszmq

Please note: the fszmq NuGet package ONLY provides the managed fszmq.dll file. You need to provide the native libzmq file(s) appropriate to your platform.


Acquiring libzmq

On Windows, the recommended solution is to download a release from the official GitHub repo and then compile it in a recent version of Visual Studio (several versions are supported... check the release docs for more information).

On macOS, the recommended solution is to install zmq from Homebrew -- the missing package manager.

On Linux, the recommended solution is install libzmq from your distro's package manager. Alternatively, you may build from source.

Please note: in a pinch, the lib folder in the root of this repo contains Windows, macOS, and Linux binaries of libzmq. But they're not compiled with all available features for all platforms and may not behave as expected.

Platforms

At this point in time, fszmq has been tested on the following platform/architecture/runtime combinations:

  • 32-bit Windows XP (running against .NET Framework)
  • 64-bit Windows Server 2008 R2 (running against .NET Framework)
  • 32-bit and 64-bit Windows 7 (running against .NET Framework or Mono)
  • 32-bit and 64-bit Windows 8 (running against .NET Framework or Mono)
  • 32-bit and 64-bit Windows 10 (running against .NET Framework, .NET Core, and Mono)
  • 32-bit and 64-bit OS X (running against Mono)
  • 64-bit Linux (Ubuntu 18.04 running against .NET Core)

Other platform/architecture/runtime combinations should work (so long as .NET Framework, .NET Core, or Mono are supported and there is a native libzmq port).


IMPORTANT NOTE: starting with version 12.3, fszmq will only ship as a .NET Standard library (currently, .NET Standard 2). This may have consequences (or limitations) for existing applications wishing to upgrade.


A note about versions

In the past, several attempts were made (poorly) to keep the version of fszmq synchronized to the version of libzmq. Starting with verion 12.0.0 (which is the twelth release... version 4.0.9 was the eleventh release), this is no longer done. Instead, fszmq is versioned independently. The versions of libzmq supported by each version of fszmq are as follows (where 'x' means any number >= 0):

fszmq version libzmq versions supported
12.3.x 4.1.x (and a sub-set of 4.2.x)
12.2.x 4.1.x
12.1.1 4.1.x
12.1.0 4.1.x
12.0.1 4.0.x
4.0.9 4.0.5
4.0.8 4.0.5
4.0.6 4.0.5
4.0.5 4.0.5
4.0.4 4.0.4
3.2.7 3.2.5
3.2.5 3.2.5
2.2.1 2.2.1
2.2.0 2.2.0
2.1.11 2.1.x
2.1.10 2.1.x
2.1.6 2.1.x
