Use Borland C++ 4.0 For Network Programming

The easiest way to compile network programming project using
Borland C++ (4.0 or above) is to compile and build the program in DOS
environment. The following steps give you some ideas how it works.

Before doing this, you have to determine where the BC binaries are
stored. In the Academic Service Building labs, they are stored in
m:\borland\bc4\bin.

1. Start the DOS prompt
2. At the DOS prompt, set the path properly by

path=$path;m:\borland\bc4\bin

3. Either save from the Web browser, or from this file, the following
makefile.bcc to a directory of your choice (typically you should put
the network program and the makefile in the same directory).

# begin of makefile.bcc
#
# Internetworking with TCP/IP, Volume III example code Makefile

CC = m:\borland\bc4\bin\bcc32 # this depends on where your BC compiler is
LINK = $(CC)                  # BC doesn't have a separate LINK
INCLUDE=-Im:\borland\bc4\include   # this depends on where your BC compiler is
DEFS = /DMT
CFLAGS = $(DEFS) $(INCLUDE)

HDR =
SRC = tcpecho.cpp tcpechod.cpp tcplib.cpp
OBJE = tcpecho.obj tcplib.obj
OBJD = tcpechod.obj tcplib.obj

all: tcpecho.exe tcpechod.exe

tcpecho.exe: $(OBJE)
	$(LINK)  $(OBJE)
tcpechod.exe: $(OBJD)
	$(LINK) -WM $(OBJD) 
tcpecho.obj: tcpecho.cpp
	$(CC) $(CFLAGS) -c tcpecho.cpp
tcpechod.obj: tcpechod.cpp
	$(CC) $(CFLAGS) -WM -c tcpechod.cpp
tcplib.obj: tcplib.cpp
	$(CC) $(CFLAGS) -c tcplib.cpp
clean:
	del *.bak
	del *.exe
	del *.obj
# end of makefile.bcc

4. Type at the DOS prompt

make -f makefile.bcc

The program should be compiled and the executable should be generated.

5. Execute the server program e.g. tcpechod first, then on the same
machine or on a different machine execute the client program,
e.g. tcpecho

Note that in the original tcpechod.cpp that I gave out, errno.h was
not included in the source code. This didn't cause problem in
VC++. But BC++ doesn't like this, so make sure the following line is
in the server (e.g. tcpechod.cpp) program

#include <errno.h>

The newer version of the tcpechod.cpp has fixed this problem.
