You may want to take a look at Inline::CPP. -- Douglas	[reply]

There's an example in Extending and Embedding Perl by Tim Jenness and Simon Cozens. A great book, by the way.	[reply]

Your best bet would be to make a C routine (with `extern "C"` declaration) which can call your C++ routine properly. Calling C++ directly is a bit of an issue thanks to a problem called "decoration" which is difficult to manage from any other language. Then your Perl can call the simple C functions in a fairly straightforward way. To see more about how to call C from Perl, see perlxs and perlguts. The inverse, how to call Perl from C, you can find in perlembed. Update: Inline::CPP is another option, but requires you to compile the code when you run the script. This may or may not be convenient for your scripting and distribution purposes. -- `[ e d @ h a l l e y . c c ]`	[reply] [d/l]
