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.
