How to get F# working with Mono?

Question

I can't seem to find a compiler/plugin for mono. Does one exist?

Answer 1

1. Go here and download fsharp.zip
2. Unzip it and open the created folder
3. Open the terminal and run ./install-mono.sh as root (On some systems, it is necessary to convert the newline characters in that script from CRLF to LF)

This will give you the basic functionality which means you will be able to run "mono fsi.exe" and compiled F# apps as "mono myApp.exe".

Usefull tips:

1. It makes sense to create scripts for the compiler and F# interactive. i.e.:

   /usr/local/bin/fsc

   #!/bin/sh exec /usr/bin/mono /usr/local/src/FSharp-1.9.9.9/bin/fsc.exe $@

   /usr/local/bin/fsi

   #!/bin/sh exec /usr/bin/mono /usr/local/src/FSharp-1.9.9.9/bin/fsi.exe $@

2. F# interactive (fsi.exe) is trying to reference System.Windows.Forms by default so in order to run it WinForms support in Mono will be required

3. fsi.exe works better in Xterm than in Gnome Terminal.
