Re^3: Extending perl with C dynamic library.

What is this "symbol" and how to add this to my .c code ?

A symbol is just a name for something, a function in this case. It you can't use XS to generate a boot_<module> function for you, you'll have to write it yourself. Not an easy task, but perhaps achievable. Try looking at *.c files generated by xsubpp from *.xs files and writing similar code manually.
