Strange. SWI-Prolog.h (which is #include'd in opaque.c) defines 'PL_blob_t' and the various 'PL_BLOB_*' constants. So - if SWI-Prolog.h has been found, those errors should not arise ... and if SWI_Prolog.h was not found, then you should also have received an error message telling you about that.(You're sure it's the updated version of pl that's being found ? .... not still getting that old SWI-Prolog.h that knows nothing of 'PL_blob_t' and friends ?)

L::P::Y-0.08 is compiling ok for me against pl-5.6.1. I'm using the MinGW port of gcc in a native Win32 environment (not Cygwin) but I would not expect that to make a big difference. And I'm using the SWI-Prolog Windows binary (apparently built using a Microsoft compiler) provided on the website. I changed the name of pl\lib\libpl.lib to pl\lib\libpl.a so that the library could be found for linking purposes. Alternatively you could probably amend the Low/Makefile.PL so that 'pl.dll' gets used for linking.

I just noticed that for Windows 95/98/ME they are recommending that you use pl-5.4.7. Is that relevant to your situation ?

Cheers,
Rob
