DBD::Sybase under Cygwin

Here's a little how-to to build DBD::Sybase in the Cygwin
(http://www.cygwin.com) environment under Windows.

First - you need to have Sybase OpenClient installed. This is pretty
easy to get from http://www.sybase.com/ase_1252devel/.

Second, you need to map the entry points to the Sybase DLLs to something
that gcc can use. I've built a set of .a files (libcs.a, libct.a and
libblk.a) that provide these entry points - you can get them from
http://www.peppler.org/downloads/cygwin.tar.gz. Install the .a files in
/usr/local/lib so that the build will find them easily.

Third, grab the most recent "dev" release of DBD::Sybase 1.04_14 or
later, available from http://www.peppler.org/downloads/).
Now build this as usual (perl Makefile.PL, etc) making sure that the
SYBASE and SYBASE_OCS environment variables are set correctly.

Et voilà!

If you don't want to download/use the dev release, you can achieve the
same result like this:

After installing the cygwin libct/cs/blk.a files, run perl Makefile.PL
in the DBD::Sybase source directory. Now edit the generated Makefile,
and add -D_MSC_VER=800 to the CCFLAGS macro, and change the EXTRALIBS
and LDLOADLIBS macros to
EXTRALIBS= -lcs -lct -lblk
LDLOADLIBS= -lcs -lct -lblk

and now run make.

For those of us who prefer a Unix-like feel this gives a nice
alternative to the ActiveState version of perl.
