Hi,

I use the Boost library 1.34.1 on Ubuntu 7.10 (Gusty Gibbon). I get
the following error while linking with libboost_unit_test_framework.

user23_at_Mycomp:~/scrapbook$ g++ first.cpp -lboost_unit_test_framework
/usr/lib/gcc/i486-linux-gnu/4.1.3/../../../../lib/crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status


The first.cpp has the example given in the Boost website

// Boost.Test
#include <boost/test/unit_test.hpp>
using boost::unit_test::test_suite;

// most frequently you implement test cases as a free functions
void free_test_function()
{
    // reports 'error in "free_test_function": test 2 == 1 failed'
    BOOST_CHECK(2 == 1); // non-critical test => continue after failure

    int* p = (int*)0;
    *p = 0;
}

test_suite*
init_unit_test_suite( int, char* [] ) {
    test_suite* test= BOOST_TEST_SUITE( "Unit test example 1" );

    // this example will pass cause we know ahead of time number of expected failures
    test->add( BOOST_TEST_CASE( &free_test_function ), 1 /* expected one error */ );

    return test;
}

// EOF


Thanks in Advance.
