Exercise 45: A Simple TCP/IP Client

I'm going to use the RingBuffer to create a very simplistic network testing tool called netclient. To do this, I have to add some stuff to the Makefile to handle little programs in the bin/ directory.

Augment the Makefile

First, add a variable for the programs just like the unit test's TESTS and TEST_SRC variables:

PROGRAMS_SRC=$(wildcard bin/*.c)
PROGRAMS=$(patsubst %.c,%,$(PROGRAMS_SRC))

Then, you want to add the PROGRAMS to the all target:

all: $(TARGET) $(SO_TARGET) tests $(PROGRAMS)

Then, add PROGRAMS to the rm line in the clean target:

rm -rf build $(OBJECTS) $(TESTS) $(PROGRAMS)

Finally, you just need a target at the end to build them all:

$(PROGRAMS): CFLAGS += $(TARGET)

With these changes, you can drop simple .c files into bin, and make will build them and link them to the library just like unit tests do.
