[Mono-dev] Compiling db4o-7.12 or 7.13

[Paul]

Hi,

Has anyone had any luck compiling db4o-7.12 or 7.13 using Mono-2.6.1?
I've tried, but keep getting the following error

gmcs -t:library  -warn:0 -out:../bin/Db4objects.Db4o.dll -debug+
-keyfile:../db4objects.snk -define:NET_2_0,MONO,EMBEDDED  @./sources
./Db4objects.Db4o/Internal/Caching/LRU2QLongCache.cs(51,36): error
CS0453: The type `long?' must be a non-nullable value type in order to
use it as type parameter `T' in the generic type or method
`System.Nullable<T>'.
Compilation failed: 1 error(s), 0 warnings

The offending code is this

public virtual object Produce(object key, IFunction4 producer,
IProcedure4 finalizer)
                {
                        if (((long)key) == null)
                        {
                                throw new ArgumentNullException();
                        }

I'm trying to compile the .NET2 version and don't know if this is a
Mono, db4o or something else problem.

TTFN

Paul
