Extend the makefile to generate a library and documentation with doxygen

Question

I have implemented a binary tree program which includes the tree.c with the functions, the tree.h with the declarations of them and a main.c for testing. Also, I have a mak

Answer 1

Well, I don't really know the syntax for the doxygen command, so I'll make a generic answer:

in your Makefile, each

term: [dep]
    action

is a target.

So if you add something like:

doc: $(OBJ)
    doxygen with-correct-options

You will be able to generate the documentation using:

make doc

(doc being here the name of the target)

Now, if you add:

all: tree doc
    @echo "Generating program and doc."

you will have the program and the documentation generated with simply invoking

make

In the end, there is an additional statment your Makefile could have use of: .PHONY. It's "A way to mark one of many targets as not directly producing files, and ensure their execution even if a file having the same name as the target exists". In other terms, it's to make sure doc, clean or all will always be executed even if files named doc, clean or all exist.

Its syntax is the following:

.PHONY: all clean doc

And is usually put at the end of the Makefile.
