Linking boost library makefile error

[exenam]

Hi!
I am to use boost library in my project. I have it already installed on Ubuntu, but when running makefile in terminal I encountered such an error:

test.o: In function `init_unit_test()':
test.cpp:(.text+0x4b): undefined reference to `boost::unit_test::framework::maser_test_suite()'
test.o: In function `main':
test.cpp:(.text+0x9e): undefined reference to `boost::unit_test::unit_test_mainbool (*)(), int, char**)'

collect2: error: ld returned 1 exit status
make: *** [proj2] Error 1

Makefile code:

all: proj2
proj2: Wrapper.o inherit.o test.o
	g++ Wrapper.o inherit.o test.o -o proj2
Wrapper.o: Wrapper.cpp
	g++ -c -Wall Wrapper.cpp
inherit.o: inherit.cpp
	g++ -c -Wall inherit.cpp
test.o: test.cpp
	g++ -c -Wall test.cpp -lboost_unit_test_framework-mt
clean:
	rm rf *o proj2

What is wrong with that?

When you invoke GCC, it normally does preprocessing, compilation,
assembly and linking. The "overall options" allow you to stop
this process at an intermediate stage. For example, the -c option
says not to run the linker. Then the output consists of object
files output by the assembler.

g++ -c -Wall test.cpp -lboost_unit_test_framework-mt 

-lboost_unit_test_framework-mt is ignored

all: proj2
proj2: Wrapper.o inherit.o test.o
	#this is the linking stage
	g++ Wrapper.o inherit.o test.o -lboost_unit_test_framework-mt -o proj2
