I'm trying to create a simple unit test (using the Unit Test Framework) using boost 1.31.0 + win32 + vc71, but I get the following linker error due to the undefined symbol __imp___CrtSetReportHook: tests error LNK2019: unresolved external symbol __imp___CrtSetReportHook referenced in function "public: int __thiscall boost::execution_monitor::execute(bool,int)" (?execute@execution_monitor@boost@@QAEH_NH@Z) There was mention of this undefined symbol (__imp___CrtSetReportHook) in this thread: http://lists.boost.org/MailArchives/boost/msg43787.php. However, that post was concerning the Metrowerks compiler, but I am using Microsoft's vc71 compiler. Can someone help me resolve this undefined symbol (__imp___CrtSetReportHook) problem? Here is my simple "unit test suite" that I am trying to build: #include #include using boost::unit_test_framework::test_suite; void test_GleamData() { BOOST_CHECK(2 == 1); // non-critical test => continue after failure } test_suite* init_unit_test_suite( int, char* [] ) { test_suite* test = BOOST_TEST_SUITE( "GleamAnalysis Test Suite" ); test -> add( BOOST_TEST_CASE( &test_GleamData ), 1 /* expected one error */ ); return test; } Warmest regards, Matt
