Hi,
I am new to linux and right now I am just following a tutorial.
I have these two files EchoClient.c and EchoServer.c and a Makefile.txt for them.Now I want to know what command do I have to execute from the shell so as to create the output of the makefile.Please let me know.

First off, a Makefile is named "Makefile," not "Makefile.anything;" that'll cause you problems.

So,

Code:

prompt: mv Makefile.txt Makefile
prompt: make

You can, actually, name a Makefile anything you want to (although that will get confusing after a while) and execute the make utility

Code:

make -f WhatEverNameYouGaveIt

and that will work but you probably see where this is going, eh? The make utility "looks for" a file named "Makefile" by default, probably a good idea to simply follow that.

Hope this helps some.

Hi Tronayne,
I am getting the following error when I executed the command you specified....

make: *** No rule to make target `EchoServer.c', needed by `EchoServer'. Stop.

Your C source files, EchoClient.c and EchoServer.c, what are they? That is, are they both main program source files? Is one a main and the other a function?

If they are both main files, a Makefile would look something like this:

Code:

MAKEFILE =      Makefile

MAINS   =       EchoClient EchoServer

OBJECTS =       EchoClient.o EchoServer.o

SOURCES =       EchoClient.c EchoServer.c

ALL:            $(MAINS)

EchoClient:             EchoClient.o
        $(CC) $(CFLAGS) -o EchoClient EchoClient.o

EchoServer:             EchoServer.o
        $(CC) $(CFLAGS) -o EchoServer EchoServer.o $(LDFLAGS)

EchoClient.o:

EchoServer.o:

It would probably be a good idea to read http://en.wikipedia.org/wiki/Make_%28software%29 to gain an understanding of what make and Makefiles are all about.

Hope this helps some.
