[Mono-list] mono under Debian : unresolved type ...

[David Marsal]

Hello !

I try to compile the following hello.cs with mcs :

using System;
public class HelloWorld {
  static void Main() {
    Console.WriteLine("Hello World!");
  }
}


but when I launch mcs I get :

unresolved type: [mscorlib]System.Reflection.MemberFilter
unresolved type:
[mscorlib]System.Diagnostics.SymbolStore.ISymbolDocumentWriter
unresolved type:
[mscorlib]System.Diagnostics.SymbolStore.SymLanguageType
unresolved type:
[mscorlib]System.Diagnostics.SymbolStore.SymLanguageVendor
unresolved type:
[mscorlib]System.Diagnostics.SymbolStore.SymDocumentType
unresolved type: [mscorlib]System.Diagnostics.SymbolStore.ISymbolWriter
/usr/bin/mcs: unresolved external references

The computer is running debian unstable with a sources.list :

deb http://www.debianplanet.org/mono unstable main
deb-src http://www.debianplanet.org/mono unstable main

As a newbie, I can't understand a single word. What I missed ?

thanks a lot for your help
