Circular dependencies
by Philippe Le Grand Feb. 24, 2007

Feb. 24, 2007

Hello All. I just checked out Python.Net from SVN and attempted to recompile it, but I ran into an apparent circular dependency problem: Python.Runtime.dll requires the ClrModule class, from clr.dll, but clr.dll needs Python.Runtime.dll to build. Am I doing something wrong? Philippe

Trying to run python.exe from pythonnet-1.0-rc2-py2.4-clr1.1-src.tgz on Fedora with Mono 1.1.13, and I'm getting this message: err:module:import_dll Library mscoree.dll (which is needed by L"Z:\\pythonnet-1.0-rc2-py2.4-clr1.1-src\\python.exe") not found err:module:LdrInitializeThunk Main exe initialization for L"Z:\\pythonnet-1.0-rc2-py2.4-clr1.1-src\\python.exe" failed, status c0000135 The site says PythonNet should run on Mono. I followed the instructions in readme.html. Is there anything else I need to do? Regards, Chris

This is a problem with the current installer for Python.NET: It doesn't have support for .NET 2.0. You'll need to compile from source (which is quite easy) in order to get 2.0 support (and support for 2.0 DLLs) Hopefully someone will have gotten around to fixing the ClrModule so that Python .NET will compile properly for 2.0.

Even if you get a 1.1-compatible version of the DLL, or you build Python.Net 2 from source, you will need to learn the namespace(s) and name(s) of the C# class(es) you want to use. From what you have below, it seems that the LoadWithPartialName call worked (so you don't need to copy the DLL to everywhere in the file system) but the import didn't. You need to know the name of the C# namespace and class to import -- as Maksim wrote from CLR.Name.Space import ClassName For you that would probably be something like from CLR.SharpNeatVendorName.SharpNeat import MainClass assuming that they follow the convention of putting their work in a namespace under a namespace based on their company/organization name. The magic of Python.Net's CLR module is that it makes the C# DLL available dynamically -- but you have to know the namespace(s) and class(es).

Yes.
