Dear Wise Monks,
I frequently run into errors like the one below when I try to install
old CPAN modules with C extensions.
IO.xs: In function `XS_Tk__IO_read':
IO.xs:258: `sv_undef' undeclared (first use in this function)
I have to go into the code and provide definitions by hand such as:
#define sv_undef PL_sv_undef
I've seen a portability header file called ppport.h included
with a few CPAN modules such as
but most older modules don't use it.
Is there something I could set up (in the CPAN module config file or
elsewhere) to solve this problem in an easier way? Thanks.
