ikegami: Did you follow the instructions at all?

Do you think XSLoader could run and produce an error message if the instructions weren't followed?

I am now looking into an option of explicitly compiling header perl.h directly into my extension library. But I am getting the error below.

My Error:

....

Any ideas monks.

Compiled EXTERN.h before perl.h removed the errors:

/usr/lib/perl/5.18/CORE/handy.h:873:1: error: unknown type name ‘EXTCONST’
 EXTCONST U32 PL_charclass[];
 ^
..

But doesn't resolve the issue undefined symbol: PL_utf8skip.
