I am very new to perl and I am trying to install DBD::DB2 module for perl on a windows PC using cpan but I keep getting this error:
CPAN: CPAN::SQLite loaded ok (v0.212)

I tried to copying the DBD::DB2 module form another computer but that did not work and gave me error Can't locate loadable object for module DBD::DB2::Constants in @INC Any help is appreciated.
回答1:
According to this technote, IBM India (possibly the maintainers of DBD:DB2) supports DBD:DB2 for Windows with ActiveState Perl. The technote also shows how to use ppm to get the pre-built module.
If you don't care about which Perl supplier , consider using Activestate Perl for Windows. If you must persist with Strawberry Perl, read on.
The current V11.1 Db2-LUW documentation also says in addition to ActiveState Perl, that 32-bit Strawberry-Perl is supported with this statement:
The working versions of Perl that works with Db2 are Activestate Perl and 32-bit Strawberry Perl. For 32-bit Strawberry Perl specifically, you must email opendev@us.ibm.com or contact IBM support for the required binaries.
If you have a support contract for Db2, you might want to check with them if the Db2 documentation is accurate (frequently for non-core stuff, it is inaccurate, out of date, misleading etc), and whether they can issue 64-bit binaries for DBD::DB2.
Looking at the CPAN page for changes to DBD:DB2, seems the most recent change was in 2012. So it is unclear if this module is maintained currently.
On the same site, there is also a reported issue opened in 2013, that DBD:DB2 fails to build with Strawberry perl.
I'm sure that a determined C programmer would be able to resolve the issue...the question is whether there are enough users to bother...

I've found a work around for this, just insert this the following files:
- Constants/Constants.xs
- DB2.h
#ifndef __DBD_DBI_FIX__
#define __DBD_DBI_FIX__
#include <specstrings.h>
#ifndef __out_ecount_opt
#define __out_ecount_opt SAL__out_ecount_opt
#endif
#ifndef __in_ecount_opt
#define __in_ecount_opt SAL__in_ecount_opt
#endif
#ifndef __out_bcount_opt
#define __out_bcount_opt SAL__out_bcount_opt
#endif
#endif
The full fix is here: https://github.com/ro-ag/DBD-DB2-1.86/commit/1ad9d4163656d9830fd567caf6d57603045ee392
You may also direct install it from a PPM package I've create for Windows 10: https://github.com/ro-ag/Perl-64-PPM/raw/master/PPM-64/DBD-DB2.tar.gz
The cpan module is forgotten i've sent several e-mails to IBM to include this fix without success.
