Hi there, I'm using boost 1.34 on MSVC 7.1. For whatever reason I cannot eliminate various linker errors. I have defined my BOOST_AUTO_TEST_CASEs in several .cpp files and this seems to create multiple definition of various symbols. The errors look as the following: string_table_test.obj : error LNK2005: "bool boost::test_tools::`anonymous namespace'::dummy_cond" (?dummy_cond@?A0x7aa5c0d5@test_tools@boost@@3_NA) already defined in ORM_test.obj string_table_test.obj : error LNK2005: "class unit_test_log_t::boost::unit_test_log_t & boost::unit_test::`anonymous namespace'::unit_test_log" (?unit_test_log@?A0x7aa5c0d5@unit_test@boost@@3AAVunit_test_log_t@23@A) already defined in ORM_test.obj Did anyone had to deal which such messages before? Thanks ahead, Christian

Hi Gennadiy, This fix only solved one of the LNK2005s. The following error is still appearing: error LNK2005: "class unit_test_log_t::boost::unit_test_log_t & boost::unit_test::`anonymous namespace'::unit_test_log" (?unit_test_log@?A0x7aa5c0d5@unit_test@boost@@3AAVunit_test_log_t@23@A) already defined in database_test.obj Does this fix only applies to MSVC 7.1 only?

Hi Gennadiy, were you able to find a solution for my problem? I would really need a fix, here. Let me know if there is anything I can help you out with. My solution right now is to put all my tests into one file which is not a good one. Thanks, Christian On 7/11/07, Christian Henning wrote:

Thanks Gennadiy, that did the trick. When do you think those changes will make it into the boost? For 1.34.1, maybe? Thanks again, Christian On 7/17/07, Gennadiy Rozental wrote:
