For a more robust solution, I'll need to take salva's suggestion

Yes, salva's solution (a salvation ?) seems like a good one - though I haven't yet been able to work out exactly how to implement it. Pointers to functions in C ? ... then wrapped in an SV ? ... that's more than enough to frighten me.
If someone feels inclined to present a simple demo of the procedure, I, for one, will certainly be taking a good look at it.

At RFC: Setting up a minGW compiling envronment for Perl 5.10 there's a long and drawn out discussion that unravels this very same issue wrt Glib and Cairo on Win32. Seems that Glib and Cairo might be much more Windows-friendly if the approach presented by salva were adopted by their developers.

is it really "dynamic linking" if you need to resolve every symbol at compile time?

The same question is asked at http://sig9.com/node/35 - and a simple demo solution that involves the LoadLibrary() and GetProcAddress() functions (from the Windows API) is provided. I imagine it would be very tiresome to attempt to incorporate that approach into portable XS code. (I note that the "solution" presented there also involves "pointers to functions".)

Cheers,
Rob
