[ubuntu] 14.04 LTS - GNU C/C++ compiler

I upgraded to 14.04 LTS and made all updates. It appears that the install includes gcc, for which the man page says to be GNU C/C++. So, I assume that a version of GNU C/C++ compiler package is installed with 14.04 LTS. I recompiled some of my c files successfully. However, when I tried to compile a C++ program via make, the error message says g++ is not found.

My simple makefile looks like this:

LDFLAGS = -lm
CFLAGS = -O3
CC = gcc

OBJS = read.o
cmp.o

read : $(OBJS) read.h
${CC} ${CFLAGS} -o $@ $(OBJS) ${LDFLAGS}

The source files are read.h, read.C and cmp.C.

Here is the error message:

:~/sbox$ make
g++ -c -o read.o read.C
make: g++: Command not found
make: *** [read.o] Error 127
:~/sbox$

Why is make/gcc looking for g++?
