OPCheck.xs:16: error: redefinition of typedef ‘Perl_check_t’
ppport.h:3976: error: previous declaration of ‘Perl_check_t’ was here
make: *** [OPCheck.o] Error 1
I changed the check for the typedef in OPCheck.xs from this:
#if PERL_VERSION < 9
typedef OP* (CPERLscope(*Perl_check_t)) (pTHX_ OP*);
#endif
to this:
#if PERL_VERSION < 8
typedef OP* (CPERLscope(*Perl_check_t)) (pTHX_ OP*);
#endif
Then it installed and the tests worked.
I asked on #devel-declare for a solution and vincent suggested that
maybe that piece of code (the #if/#endif) should be removed because
you're code is now importing ppport.h (which contains the OP* typedef).
I'm not sure if this is the solution, but removing the definition made
everything work (tests pass etc.).
