I have a library written in C# -- Foo.dll. I am able to load rdnzl in clisp, and run simple examples that involve importing registered libs: "Hello World!", etc. No matter where I put Foo.dll, (load-assembly "Foo") results in:
WARNING: Returning NULL object from .NET call NIL
You should succeed if you put Foo.dll in the folder where your CLISP executable is (/before/ you start CLISP).
When I specify a full path: (load-assembly "c:\Documents and Settings\user\Desktop\Foo.dll")
I get:
*** - .NET error (System.IO.FileLoadException): The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
LOAD-ASSEMBLY uses System.Reflection.Assembly::LoadWithPartialName internally - that one doesn't work with full pathnames.
I'm not sure what to do at this point.
(rdnzl:invoke "System.Reflection.Assembly" "LoadFrom" "c:\Documents and Settings\user\Desktop\Foo.dll")
should give you the assembly.
HTH, Edi.
PS: See the notes in the documentation about CLISP. You should try one of the Lisps that are fully supported instead.
