Hello monks, I need some help with using c functions in s a PERL script. I have read through the perlxstut, and I think I get the concepts, and I was able to get the very first example to work, but not all the others. I have what I think should be a very simple extension. I have two files provided to me by my instructor: hilbert.c and hilbert.h, although they are very long they are reallt just a couple of functions to return a hilbert curve index given a point, and to return coordinates given a hilbert index. I wish to use these functions in a PERL script, but can't seem to get from perlxstut examples to actually applying it to my library. I didn't post the c files here, but will be glad to email them if someone is generous enough to help. Right now I am at the part where I have a Hilbert subdirectory, and I was able to run nmake but I can't use the dll file that was created, (Pretty sure there is nothing in it). If someone could provide or point to a more step by tutorial for xtending PERL with an existing h 7 c file I would ber grateful. If someone is so inclined to provide the tutorial themselves I can email the c header files. Thanks.
