in thread Installation of DBD::Sybase with Strawberry Perl

In order to make sure that the library does contain function references use nm -a or some windows equivalent.

But why does the Makefile runs the compiler with these 2 flags: -DWIN32 -DWIN64. They seem contradictory to me? If you are linking 32 bit libraries with 64 bit perl you are most likely have problems.

    They're actually part of perl's ccflags: 
    C:\perl -V:ccflags
ccflags=' -DWIN32 -DWIN64 -D__USE_MINGW_ANSI_STDIO -DPERL_TEXTMODE_SCR
+IPTS -DPERL_IMPLICIT_CONTEXT -DPERL_IMPLICIT_SYS -DUSE_PERLIO -fwrapv
+ -fno-strict-aliasing -mms-bitfields';

    WIN32 is a symbol that's defined on all Windows systems (both 32-bit and 64-bit). I don't think there's any need to specify it.
    Defining WIN64 specifies that you want to operate in 64-bit mode, and that the compiler is 64-bit..

      Oh ok thanks, so I understand that WIN32 has nothing to do with 32bit vs 64bit. It's just the presence or absence of WIN64 that does that. Then perhaps it is worth to check if sybase libs are 64bit as well although that may throw other error messages.

        If that were the case then there should have been some warnings about ignoring incompatible libraries .... and maybe there were! (We don't really know.)

        So, yes, this should be checked.
