Hi list.
I'm trying to compile and run simple unit test, but only to fail:
#include
using namespace std;
using namespace boost::unit_test;
using namespace boost;
void force_division_by_zero()
{
BOOST_CHECKPOINT("About to force division by zero!");
int i = 1, j = 0;
i = i / j;
}
test_suite*
init_unit_test_suite(int, char*)
{
test_suite* test = BOOST_TEST_SUITE("Unit test example2");
test->add(BOOST_TEST_CASE(&force_division_by_zero), 1);
return test;
}
This does not compile though this is the program shown in the document.
The errors are:
/usr/lib/gcc/x86_64-redhat-linux/4.0.2/../../../../lib64/crt1.o

I'm compiling the sorce like g++ filename.cpp. My environments:
$ g++ -v
Using built-in specs.

Any idea?
