Re: gcc for building Perl on WinXP

Chris,

that sounds great, however my attempt ended up with:

C:\strawberry\perl\bin\perl.exe C:\strawberry\perl\lib\ExtUtils\xsubpp  
-typemap C:\strawberry\perl\lib\ExtUtils\typemap -typemap typemap  
Core.xs > Core.xsc && C:\strawberry\perl\bin\perl.exe 
-MExtUtils::Command -e mv -- Core.xsc Core.c
Could not find a typemap for C type 'PDL_Long *' in Core.xs
