Create Makefile from source files
1. The problem statement, all variables and given/known data:

Create a makefile for a set of source files. Several sources files are given but we are not allowed to modify them. The goal is to create a makefile such that if a change is made to any of the source code files, the project can be rebuilt by typing make at the command line.

2. Relevant commands, code, scripts, algorithms:

use vi in unix environment; -o, -I, -c

3. The attempts at a solution (include all code and scripts):

Code:
all: frprog gqprog vwprog

frprog: fr.o
        g++ -o frprog fr.o

fr.o: fr.cc pg.h
        g++ -c fr.cc

gqprog: gq.o
        g++ -o gqprog gq.o

gq.o: gq.cc ac.h bb.h
        g++ -c gq.cc -I/includes/bb.h

vwprog: vw.o
        g++ -o vwprog vw.o

vw.o: vw.cc ac.h
        g++ -c vw.cc

ac.o: ac.cc ac.h pg.h
        g++ -c ac.cc

pg.o: pg.cc pg.h
        g++ -c pg.cc


clean:
        -rm *.o

Code:
g++ -o frprog fr.o
fr.o: In function `main':
fr.cc:(.text+0x21): undefined reference to `f1()'
collect2: error: ld returned 1 exit status
Makefile:4: recipe for target 'frprog' failed
make: *** [frprog] Error 1
make: *** No rule to make target 'bb.h', needed by 'gq.o'.
g++ -o vwprog vw.o
vw.o: In function `main':
vw.cc:(.text+0x21): undefined reference to `x2()'
collect2: error: ld returned 1 exit status
Makefile:16: recipe for target 'vwprog' failed
make: *** [vwprog] Error 1
make: Target 'all' not remade because of errors.
