Hello! The current CVS version of the TR1 library has two tests named "test_complex", as the following output demonstrates: $ bjam tr1_has_tr1_array_fail -n --dump-tests | grep test_complex boost-test(COMPILE) "tr1/test_complex" : "libs/tr1/test/test_complex.cpp" boost-test(COMPILE) "tr1/std_test_complex" : "libs/tr1/test/test_complex.cpp" boost-test(COMPILE) "tr1/test_complex" : "libs/tr1/test/test_complex.cpp" There are three tests reportedly using "test_complex.cpp", and two tests named "tr1/test_complex". However, regression results at: http://engineering.meta-comm.com/boost-regression/CVS-HEAD/developer/tr1.htm... mention only one test named "test_complex". Further, the first "test_complex" comes from this loop in Jamfile: for local file in [ GLOB $(BOOST_ROOT)/libs/tr1/test : test*.cpp ] { all_rules += [ compile $(file) : <include>$(BOOST_ROOT) ] ; and the second "test_complex" comes from this loop: for local file5 in [ GLOB $(BOOST_ROOT)/libs/tr1/test/std_headers : *.cpp ] { all_rules += [ compile $(file5) Note that the output of --dump-tests reports wrong name for the second "test_complex" -- libs/tr1/test/test_complex.cpp instead of libs/tr1/test/std_headers/test_complex.cpp I looks like there are two issues in regression system: 1. --dump-tests reports wrong file name 2. The reporting tools don't handle two tests with the same name. Finally, when using Boost.Build V2, instead of above silent issues I get loud complaint right away. So, maybe it's a good idea to add explicit suffix to tests, for example using the following patch: --- Jamfile 12 Dec 2005 18:05:26 -0000 1.10 +++ Jamfile 1 Feb 2006 15:38:17 -0000 @@ -84,7 +84,7 @@ <borland-5_5_1><*><include>$(BOOST_ROOT)/boost/tr1/tr1/bcc32 <borland><*><include>$(BOOST_ROOT)/boost/tr1/tr1/bcc32 <include>$(BOOST_ROOT) - <define>TEST_STD=1 ] ; + <define>TEST_STD=1 : $(file5:B)_header ] ; } Thanks, Volodya
