Unable to compile DBSC 2.5.2

Hello all. I downloaded the DBSC 2.5.2 codebase, in an attempt to play around and maybe learn a bit of coding and mainly building. I run a windows vista system, so I'm using cygwin to do this. There were install instructions, which I followed to the T, except selecting the "Base - Zlib" when installing cygwin (because it wasn't even an option actually). Now, I commented out the line in the makefile it says in order to compile with cygwin and use the MCCP. I type in the make command in cygwin, and I get an error...I searched the forums and never found an actual answer to this and hope to get some help.

here is the error I'm seeing:

cannot find -lz
collect2: ld returned 1 exit status
make[1]: *** [dbs] Error 1
make[1]: Leaving directory '/home/username/src'
make: *** [all] Error 2

One more note. I decided to attempt to start it anyways, after typing the command "./startup" it says the following:

limit: Command not found.
ulimit: Command not found.
mv: cannot move '../log/syslog.9' to '../log/archived/1000.log': No such file or directory.

Then the last line just keeps repeating over and over again and I can't do anything with cygwin.

So did you not install zlib? You need to.

Okay. I went to the website and downloaded the source file, unzipped it. Do I then just copy those files into my cygwin folder and use the make command? Which I have already done, but I still get the same errors as before.

No, you need to install it. Check the docs.

Or maybe it is slightly harder. But you should end up with the file libz.a somewhere in the search path for libraries, I think.
