You could think about providing RDNZL in a binary package, with the header and the import library file. Especially if you want it to be usable with other compilers like MinGW; then the user won't probably have VS200X installed. Michael.

The header can be created by: grep -E '__declspec(dllexport)' *.h | sed -e 's/dllexport/dllimport/g' The import lib file is created by VS200X when building the DLL. Michael.

[rdnzl-devel] RDNZL C++ used in non-LISP environment
by Goffioul Michael 26 Oct '06

26 Oct '06

Hi all, Recently, I had the idea to try to bridge .NET with Octave (the Matlab clone). Instead of re-inventing the wheel, I wondered "why not try to re-use RDNZL DLL?". And it worked pretty well. Actually, RDNZL provides everything you need to bridge a C/C++ application with .NET, without having to handle the managed part yourself. It's not really bound to LISP. To ease my work, I created a header file and import library, such that my octave module is linked with the RDNZL DLL. So I wondered if these files could not be provided in some stand-alone RDNZL.DLL package, such that it could be used by anybody. The import library only publishes C function, so you can even think of providing such a library for MinGW compiler (although I didn't try). What do you think? Michael.

OK, so I tried with Corman Lisp 3.0 (using CREATE-THREAD) - no problems, no locking, like with LispWorks. Maybe someone on this list can try the same with ECL, so we've covered all Lisps on Windows with MP capabilities. > I got a response from Charley Cox that suggests another route is > needed around this, or I guess I will just have to consider changing > my model of how to program. Yeah, or you change your Lisp implementation... :)

Again, I don't think this is a problem of RDNZL but rather of how the various Lisp implementations handle callbacks into Lisp. The following code works fine (output as expected, no IDE locking) for me with LispWorks 5.0 and AllegroCL 8.0 (using SLIME) - it crashes with Corman Lisp 3.0, though. Cheers, Edi.

As there is no assembly with that name, the failure is what has to be expected. > But that does not work. Instead you have to do this > > (import-type "System.Threading.Thread") > (import-type "System.Threading.ThreadStart") Yep, that's the correct way to do it.

I think that's a problem related to the IDE and not to RDNZL. In LispWorks 5.0, for example, if I start the apropos example coming with RDNZL (which also uses Application.Run) with MP:PROCESS-RUN-FUNCTION as suggested in the RDNZL documentation it runs fine without locking the IDE, i.e. I can still use the listener or other graphical tools while the .NET window is up and interacting. > How can I do this in rdnzl? Can I mix CG and rdnzl? I don't know much about CG but I think that will be very hard or impossible. But that's not a problem of Lisp/RDNZL. I think it would be equally hard to mix a C++ program using MFC with a C# program using .NET's windows forms.
