C++ Example

Suppose you have a program of five source files and the makefile:

manythreads.cc

Makefilemany.cc

thr.cc

misc.h

defines.h

The target files are many, manythreads, and thrI.

The makefile looks like this:

all: many manythreads thrI

many: many.cc
      CC -o many many.cc -g -D_REENTRANT -lm -lnsl -lsocket -lthread
thrI: thr.cc
      CC -o thrI thr.cc -g -D_REENTRANT -lm -lnsl -lsocket -lthread
manythreads: manythreads.cc
      CC -o manythreads -g -D_REENTRANT manythreads.cc -lnsl \
      -lsocket -lthread

The first line of this makefile groups a set of targets with the label all. The succeeding lines give the commands for making the three targets, each of which has a dependency on one of the source files.
