C Compiler for SCO Openserver 5.0.5

I am using SCO Openserver 5.0.5 and am trying to install a Moxa Nport N5110A Serial Device Server to run a printer.
Part of the install is to run 'make sco'.  When I do so I get 'make cannot find'

I have installed gcc, gnu tools & make which I downloaded from the net, but when I try running make I get a long list of files/directories not found.

I have attached the 'tar' file for the install.  If you vi Makefile there is a line for make sco 'cc -0' etc. That's where I get the error.

I need something that will allow me to complete the install

Looks like you need to install system libraries:

Thanks for that.  I have downloaded and installed both gcc-2.95.2-VOLS & Make-3.78.1-VOLS, but they didn't help.
Have I used the wrong files? Is there something I've missed?  Am I an idiot?

You're basically talking to a dummy novice about this

The part I was talking about was this:

[Important Note for OpenServer Users]: The GCC package for OpenServer requires system libraries and headers. Even if you do not have a licensed Caldera development system, you are licensed to use these at no cost and they are available on your installation media. Install them thusly:

Invoke custom
Select "Install New" option from the "Software" menu.
Follow the prompts to steer custom toward the original media you used to install OpenServer 5.
Select Application Development Libraries and Linker. Install it all. This will give you the libraries, headers, and man pages.

Did that and installed the Application Development Libraries & Linker.
Ran 'make sco' but got the same error.
So I thought I'd be smart and edited the Makefile file so the line for sco read 'gcc' instead of cc.
Ran 'make sco' again and after about 5 seconds the # prompt re-appeared with no errors.
I assume it worked.
Let you know if I can get the printer to work in a day or two
Hopefully it worked.  I thought part of the SCO lib install was to link gcc and cc - could be the order in which things get installed.  This is a very old OS...
