F# with Mono + Ubuntu Feisty Fawn (7.04)
f#compiler

Hello,

In order to learn F#, I would need to use it at home: that means with Ubuntu Feisty Fawn.

I tried but experienced one core dump, during the aot compilation.

During Compiler10.dll AOT compilation, I first get a warning, about System.Windows.Forms, followed by a stack trace.

--------------------------------
Pre-compiling FSharp.Compiler10.dll (may take a while)...
Mono Ahead of Time compiler - compiling assembly /home/matt/Desktop/FSharp-1.9.2.9/bin/FSharp.Compiler10.dll

** (bin/FSharp.Compiler10.dll:6676): WARNING **: The following assembly referenced from /home/matt/Desktop/FSharp-1.9.2.9/bin/FSharp.Compiler10.dll could not be loaded:
     Assembly:   System.Windows.Forms    (assemblyref_index=4)
     Version:    1.0.3300.0
     Public Key: b77a5c561934e089
The assembly was not found in the Global Assembly Cache, a path listed in the MONO_PATH environment variable, or in the location of the executing assembly (/home/matt/Desktop/FSharp-1.9.2.9/bin/).
----------------------------------

My first question is: did anybody successed with aot compiling on Mono, or is it still impossible?

Second question: I then tried to compile the following one line hello.fs, but experienced the very same message... Is the problem a F#, a Mono, an Ubuntu or a Debian one? In other world, who can help me?

---------------- hello.fs -----------------------

printf "Hello World!\n"

Thanks in advance

I've installed F# successfully with SUSE and MONO, but that was a while ago. I don't remember seeing your problem when I installed it. This is a bit of a stab in the dark but my guess is that MONO has a System.Windows.Forms dll ([link:www.mono-project.com]) but you haven't installed it, or more specifically version 1.0.3300.0 isn't available. This winforms dll is automatically referenced by the compiler and thus is giving you grief.

If you don't want to install this dll or it is installed and its a version problem you can resolve, you may want to try compiling using the --no-framework switch. Which will stop it referencing framework libraries automatically. You will of course need to then add the system libraries you do need to compile command by hand ie -r mccorlib.dll -r System.dll etc. ...

Thanks Robert,

after your answer, I explored the package manager.

I found and installed libmono-winforms1.0-cil package.

libmono-winforms2.0-cil only was on my PC.

The aot compilation worked.

And hello.fs and helloform.fs are also working.

I know have to uninstall all the othe packages I downloaded today, in order to check if the one I listed above is enough...
