Hello, sigh...the erros seem like without end. Does it happen to you
guys that debugging takes much much longer time than actual coding ?

It is called yak shaving*, and, yes, constantly.

Here I have problem of building Language::Prolog::Yaswi at
http://search.cpan.org/~salva/Language-Prolog-Yaswi-0.14/Yaswi.pm
It's an XS module. Recently, before I upgrade from perl 5.8.8 to
perl 5.10 I have not problem building this module.
snip

Low.xs: In function ‘XS_Language__Prolog__Yaswi__Low_END’:
Low.xs:50: error: ‘my_cxt_index’ undeclared (first use in this
function)
Low.xs:50: error: (Each undeclared identifier is reported only once
Low.xs:50: error: for each function it appears in.)
Low..xs: In function ‘XS_Language__Prolog__Yaswi__Low_start’:
Low.xs:68: error: ‘my_cxt_index’ undeclared (first use in this
function)
snip
Any idea why ? Thanks.

Sounds like you are missing header files for some library.

Not sure what library, but it does compile successfully previously. Thanks


if I use perl-5.8.8 to build it has not problem, but if I use perl-5.10 it will give those errors. I thought that the file Low/ppport.h that it's using is perl-5.8.8 so I generate a new ppport.h for perl-5.10 but it still gives the same error. Thanks
