Re^6: Installation of DBD::Sybase with Strawberry Perl

But why does the Makefile runs the compiler with these 2 flags: -DWIN32 -DWIN64

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';
[download]

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..

Cheers,
Rob

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.	[reply] [d/l] [select]

Then perhaps it is worth to check if sybase libs are 64bit as well although that may throw other error message 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. Cheers, Rob	[reply]
