Boost Unit Test Entry Point Issue - c++

Question

Here's the code I'm working with in Eclipse CDT (from the official boost doc http://www.boost.org/doc/libs/1_55_0/libs/test/doc/html/tutorials/hello-the-testing-world.html):
#define BOOST_TEST_MODULE MyTest
#include <boost/test/unit_test.hpp>
int add(int i, int j) {
return i + j;
}
BOOST_AUTO_TEST_CASE( my_test ) {
// seven ways to detect and report the same error:
BOOST_CHECK(add(2, 2) == 4); // #1 continues on error
BOOST_REQUIRE(add(2, 2) == 4); // #2 throws on error
if (add(2, 2) != 4)
BOOST_ERROR("Ouch..."); // #3 continues on error
if (add(2, 2) != 4)
BOOST_FAIL("Ouch..."); // #4 throws on error
if (add(2, 2) != 4)
throw "Ouch..."; // #5 throws on error
BOOST_CHECK_MESSAGE(add(2, 2) == 4, // #6 continues on error
"add(..) result: " << add( 2,2 ));
BOOST_CHECK_EQUAL(add(2, 2), 4); // #7 continues on error
}
When I try to build it in Eclipse or the terminal, I get an error message regarding the lack of an entry point or main function:

Putting a main function in the code causes the program to build fine, but then the tests are skipped entirely. I installed boost test using synaptic package manager so it should be almost plug and play minus the part where I specify the library(-l) as boost_unit_test_framework.
I've been able to get boost/test/minimal.hpp linking and working just fine, but unfortunately I haven't got boost/test/unit_test.hpp working nicely in Eclipse in which the unit test output is shown within the C/C++ Unit view. I've tried going through several official and unofficial boost documentation/tutorials and haven't been too successful. I'm trying to get to a point where I can start unit testing within Eclipse where it's somewhat similar to the comfortability of using JUnit inside Eclipse. Any help or suggestions is appreciated. Thanks.

Figured it out. Turns out I should have avoided installing framework libraries through the package manager. It's best to install from source so you know where everything is. These two docs helped:
http://ubuntuforums.org/showthread.php?t=1180792
and for generic situations dealing with shared libraries (i.e. right after the bjam installation phase):
http://www.cprogramming.com/tutorial/shared-libraries-linux-gcc.html
I'm not exactly sure where the package manager put the libraries, but I needed to verify the integrity of linking at link-time and at run-time by making sure I put the library files in /usr/local/lib and then following up with ldconfig.
