I get ERROR: Could not run Fanx.Tools.Fan to standard output when I run fan -version --Dfan.runtime=net

I have .NET versions: .NET CLR 1.1.4322; .NET CLR 2.0.50727

I searched both google and fan.org for the error phrase, and neither turned up anything that looked like it might be relevant.

Running with fan_launcher_debug=true gives:

ERROR: Could not run Fanx.Tools.Fan

(I added extra line breaks because preview button showed debug output all on one line)

I'm on Windows 2003, 32 bit, using Fan 1.0.35. Use with Java seems to work fine.

Any ideas?

Thanks, Sam

PS: I got the following error when posting this. Not sure how I'll fix it yet.

You have errors in your fandoc:

* Invalid annotation [0] [Line 57]

Tried removing space with "= C:\dev\rel" as I noticed it was blockquotes / codified in preview. Didn't work.

Removed /C: in the c:/dev/rel. Didn't work.

Tried it in another group (from the "C:/dev/fan/src/" lines.

Removed all double dashes from Fan output, changed square brackets to parentheses. If this is posted, that fixed it.

Hi Sam,

I've probably failed to mention it, but build 1.0.35 doesn't support .NET (sorry - I should have made that clear). The last few builds have all the compiler and fcode changes for nullable types and value types. However Andy just pushed .NET support for those changes to Mercurial this morning (and he still has some bugs to fix). So we won't have .NET up and running again until the next build.

You have errors in your fandoc:

The simplest thing is typically just to indent everything 2 or more spaces and it turns into a code block.

Cool, thanks for the info.

Is there a place to download prior versions, and/or build from source? Failing that, when do you expect to make the next build available?

Thanks, Sam

You can download old builds from here or really old builds from here.

You can review the changelog to pick an older build. I'd say build 1.0.32 is a good build if you want .NET.

Or you can rebuild from source - pull from hg here and follow these instructions (still a bit rough around the edges).

Thanks Brian. Still having troubles with .NET in version 1.0.32. However, I was able to at least get the -Dfan.runtime=net to run under 1.0.30.

I've included error info below, if it will help you.

Now trying to run hello world example script under .NET (having used set fan_runtime=net) still getting Null reference errors:

The code was: class Shizzle {

static Void main(){ 

echo("hello world #2") } }

And of course works fine under Java.

Just letting you know - dunno if it's helpful.

I played around with build 32 and couldn't reproduce that. If I followed that, no version really works is that correct? Are you running 64-bit .NET?

No, this is in Windows 2003.

Ok, well I tested on my machine against build 32 and it works ok, so something fishy is going on. However, a lot of code has changed since then, so lets hold off until we roll out the next build (probably next week), which has the new .NET runtime changes, and I'll get you to try it again.

Sounds good to me.
