F# support for Monodevelop

Thanks for you work...

Unfortunately, i'm new to monodevelop and i don't manage to build the FSharpbinding solution with Monodevelop : i get 6 errors about "cannot find metadata file... " concerning MonoDevelop?..dll files

I'm using Monodevelop 1.9.1 (2.0 Alpha) as i'm using Mac OS X.

Hi! I am having the same problem that davnul. Only I get 6 "cannot find metadata file" for files supposedly on my home directory and 4 for other files. Sorry but I am really new to MonoDevelop? (and Mono/.Net in general). Any help will be appreciated.

for the MonoDevelop?.Projects.Parser error, modify the three files to reflect this change:

using MonoDevelop?.Projects.Parser; -> using MonoDevelop?.Projects.Dom.Parser;

Another newbie to Mono/MonoDevelop??...

I have "fixed" references, updated the using statements (as per zorglub421's instructions), but now I'm getting the following error:

.../FSharpBinding/Gui/CodeGenerationPanel??.cs(51,47): error CS0030: Cannot convert type MonoDevelop?.Projects.ConfigurationParameters?' to FSharpBinding.FSharpCompilerParameters' .../FSharpBinding/Gui/CompilerOptionsPanelWidget??.cs(44,72): error CS0030: Cannot convert type MonoDevelop?.Projects.ConfigurationParameters?' to FSharpBinding.FSharpCompilerParameters'

I'm using the 2.0 distribution with Ubuntu 9.04

Any help would be appreciated.

Got the same cast issue than the gentleman right above. I'm using monodevelop 2.1 snapshot of around 2009-05-05, the one used to issue the precompiled .DMG for MAC OSX. Mono is release 2.4. Such a pitty. Would like to learn F# on this platform. I'm a GUI frustrated OCaml'ers :-)

Line=51, Column=73, Type=Error, Priority=Normal, Description=Cannot convert type `MonoDevelop.Projects.ConfigurationParameters' to `FSharpBinding.FSharpCompilerParameters'(CS0030)?

There seems no copy constructor from `MonoDevelop?.Projects.ConfigurationParameters?' (public ConfigurationParameters? {get; set;}) to `FSharpBinding.FSharpCompilerParameters'.

In the C# source file CompilerOptionsPanelWidget?.cs, the programmar is likely to cast in two steps.

DotNetProject? project -> DotNetProjectConfiguration?

-> FSharpCompilerParameters

As my environment is Fedora 11 development, mono 2.4 (new!, not 2.0), and MonoDevelop? 2.0 (not alpha), there might exists a slight language change of C# for mono (gmcs).

Line=51, Column=72, Type=Error, Priority=Normal, Description=Cannot convert type `MonoDevelop.Projects.ConfigurationParameters' to `FSharpBinding.FSharpCompilerParameters'(CS0030)??

Line=44, Column=98, Type=Error, Priority=Normal, Description=Cannot convert type `MonoDevelop.Projects.ConfigurationParameters' to `FSharpBinding.FSharpCompilerParameters'(CS0030)?

Will tell more please dostpney how to fix it?

Thank you for plugin.

I have same question as p.westcott. Can you please provide information how can I fix this problem?

I am using Monodevelop 2.0. Which file is the FSharpBinding solution?? FSharpBinding.mds? If FSharpBinding.mds is the solution file, then I am getting 10 errors "cannot find metadata" errors as other posters reported. I don't understand the solution advocated by zorglub421 .... please help ...

Regards,

Vasili

BTW:

Open FSharpBinding solution in Monodevelop Check and fix references

What does "Check and fix references" mean?

Vasili

Vasili: The references, for MonoDevelop? namespace, in the project are wrong and needs to be re-added.

Still, the code is out of date for MonoDevelop? 2.2. IDotNetLanguageBinding seems to have changed a lot. I tried to fix it but gave me strange errors at the time, and I'm no expert at C# so I simply gave up, sorry.

I've created a patch that allows FSharpBinding revision 26 (current trunk) to compile cleanly against MonoDevelop? 2.0. Don't know how to attach files here so see the patch inline below.

Attached a working patch to defect 2 in the issue tracker.

In monodevelop.i686 0:2.1.0-4.fc12, I still need modifications; for example, pkg (in pkgs) -> pkg2 (?), to avoid conflictions of namespace. I think the brace / indent is misleading. (See the errors in FSharpBindingCompilerManager.cs)

In my convention, not

if () {

something

but

if () {

something

is the case. (However, it is not fruitful to argue conventions here.)

I still have 10 errors of the followings,

I will think of it later.

I successfully compiled the binary and copied the MonoDevelop?.FSharpBinding.dll file to ~/.config/MonoDevelop?/addin . But still on running monodevelop i dont see an option to add F# .....

Can anyone tell me what's happening here??

Just an FYI, the instructions say deploy to ~/.config/MonoDevelop?/addin/ when you should be deploying to ~/.config/MonoDevelop?/addins/

Hi,

The patch from issue #2 that fixes compilation issues and other problems has been rolled into branch fsharpbinding-v2.0.

The add-in can be built from the command line using standard ./configure; make. It auto-configures during the build for the version of MonoDevelop? that you use. The build also creates the Mono repository, which allows you to install the add-in using MonoDevelop? GUI (Tools -> Add-in Manager -> Repositories… then Install Add-ins) or the command line tool mdutil (see build log for details).

Once you've installed the add-in, don't forget to set F# compiler path (Edit -> Preferences -> Other -> F#).

Cheers!
