No, it won't matter if a different compiler is used. > I have tried . Win32::API, Win32:API:Prototype > I don't use either extensively. I think there are still problems with Win32::API if the dll wasn't built with stdcall calling convention (which may well be the case with this specific dll) - though I think someone has made a patched version of Win32::API that doesn't require the stdcall convention. Googling for Win32::API and stdcall might turn it up. > > My latest attempt is to learn how to use Inline module which claims > to be easier than both XS and SWIG. > I use Inline a lot and I think that's a valid claim. It's also good for accessing functions in dll's. (There's a good example in the Cookbook that comes with the Inline source.) I don't know anything about swig, but with both xs and Inline::C, you'll need an import lib (.lib) as well as the dll to access the function, if you use a MIcrosoft compiler. MinGW (gcc) will probably access the function directly from the dll, but that's not possible with a Microsoft compiler. However, it's probably not difficult to create an import lib from the dll. > > LINK : error LNK2001: unresolved external symbol [EMAIL PROTECTED] > blib\arch\auto\ans_pl_d0f9\ans_pl_d0f9.dll : fatal error LNK1120: 2 > unresolved externals > NMAKE : fatal error U1077: 'C:\WINDOWS\system32\cmd.exe' : return code > '0x460' > Stop. > Still looks to me like a problem with the compiler. Best to install Inline from the cpan source, rather than the ppm. When you do that, you will probably find that 'nmake test' produces similar failures.
