_TEXT Segment Exceeds 64K

I just inherited some c code which runs on a Janus barcode scanner device.
It was developed using the Borland C compiler on the PC.  I guess the
barcode device runs a mini version of DOS.

I've made no source changes yet, I'm trying to get the existing code to
build using the Borland C++ 4.5 environment.

Problem #1 - I get a bunch of warnings from Bcc regarding 'Possibly
incorrect assignment...' and then a message:

Error: Unable to execute command 'tlink.exe'

Problem #2 - When I run tlink manually, I get the the following error:

>tlink esd.obj d:\bc45\lib\ch.lib
Turbo Link  Version 7.00 Copyright (c) 1987, 1994 Borland International
Error: Segment _TEXT exceeds 64K

Thanks for any insight you have.

P.S.

I have used the -mh option for Bcc to indicate the huge memory model, and as the tlink command line indicates, I have been attempting to link with ch.lib library for the huge memory model.  Is there something I'm missing in the Borland command line directives?

I think the second problem is because you are using a wrong memory model. Check what the documentation says you must use, if no documentation or no info about memory model, try to use large or huge memory model.

The first problem, part 2, unable to execute command tlink.exe is often cause by a wrong setup. I.e. the setup don't point to the library with the tlink, or no path to the program.

The first problem, part 1, it is a warning, so dont care if you haven't changed the program.

It turns out that my question was more about the specific installation and project settings for Borland C++ V4.5 than about the c language.  Tovergaard's answer pointed me in the right direction.
