Subject: [Python.NET] vs2010 DotNet 4?
Message-ID: <CAN-qvVe4R1bADfNogV3MzynNTTy5jy89Ug3rS9BbvcM9MOaFrQ@mail.gmail.com>

The first thing one seems to have to do is define UCS4

Upon trying out building the PythonDotNet source tree with 2010 and
dotnet 4 with UCS4 I get a bunch of errors related to the use of a
namespace Mono.  I tried excluding the monosupport.cs file, but the
runtime.cs file seems to require it as well.

It makes use of the Utf32Marshaler defined in monosupport.cs.

Has no analogous work been done for Microsoft dotnet 4?

Thanks,

Mark.
