I'm writing a C++ static library that needs to be shared among several applications, one of them written in Perl. Unfortunately, I only barely know the core Perl language (I read the Llama book), and I'm not all that familiar with its libraries. How do you make calls to an external C++ binary from a Perl script?
By Google search, I found information on the Perl Inline module, but if I understand it correctly, that isn't what I need. I'm pretty sure that's for writing C and C++ code directly in your Perl scripts, not for calling external C++ libraries.
The C++ static library is being cross-compiled for an ARM processor, so there will be no C++ compiler on the target machine where the Perl script will be running. (If that makes a difference.)
You want to look at using XS, which is how Perl normally interfaces with C/C++ libraries. It's not quite trivial. A couple of relevant portions of the Perl documentation:
