[Mono-devel-list] mod_mono error: The path is not of a legal form

[Mike McKay]

I am trying to use mod-mono to run aspx pages that refer to code that 
needs to be compiled on the fly.

This is the aspx page:

<%@ Page language="c#" src="Wiki.aspx.cs" AutoEventWireup="false" 
Inherits="MonoWiki.Wiki" validateRequest="false" %>

When I try and run it though, I get this:

(hacked down for your reading pleasure)
System.ArgumentException: The path is not of a legal form
Parameter name: path
inSystem.IO/Path.cs:202) System.IO.Path:GetFullPath (string)
CacheDependency.cs:174) System.Web.Caching.CacheDependency:CreateWatcher 
CacheDependency.cs:164) System.Web.Caching.CacheDependency:.ctor 
CacheDependency.cs:81) System.Web.Caching.CacheDependency:.ctor 
CachingCompiler.cs:144) System.Web.Compilation.CachingCompiler:Compile
TemplateParser.cs:437) 
System.Web.UI.TemplateParser:GetAssemblyFromSource ....... (snipped, it 
goes on)

Following the trail through the source it looks like some sort of path 
variable is empty. From TemplateParser.cs I found this:

     Assembly GetAssemblyFromSource (string vpath)
     {
       vpath = UrlUtils.Combine (BaseVirtualDir, vpath);
       string realPath = MapPath (vpath, false);
       if (!File.Exists (realPath))
         ThrowParseException ("File " + vpath + " not found");
       AddDependency (realPath);
       CompilerResults result = CachingCompiler.Compile (language, 
realPath, realPath, assemblies);

Which wasn't terribly helpful, but perhaps to one of you it is.

I suspect my mod_mono configuration might be wrong. This is what it my 
httpd.conf looks like:

LoadModule mono_module        /usr/lib/apache/1.3/libmod_mono.so
AddModule mod_mono.c

Alias /mono "/var/www/mono"
MonoApplications "/mono:/var/www/mono/"
MonoPath "/var/www/mono/bin/"
MonoDocumentRootDir "/var/www/mono/bin/"
<Directory /var/www/mono/ >
   SetHandler mono
   Options Indexes FollowSymLinks
   <IfModule mod_dir.c>
     DirectoryIndex index.aspx index.html
   </IfModule>
</Directory>

Others seem to have the same problem:

2) http://bugzilla.ximian.com/show_bug.cgi?id=66094

The recommendation from 1, of running xsp with a root option didn't make 
a difference:
mono /usr/bin/xsp.exe --root FOLDERNAME

And from 2), my path to mcs if pretty normal: /usr/local/bin/mcs

Does anybody have any ideas?
