Testing Outcome on MSVC, I get: C:\Users\ned\Downloads\boost_1_71_0_b1_rc1\boost_1_71_0\libs\outcome\test>..\..\..\b2 toolset=msvc-14.0 Performing configuration checks - default address-model : 32-bit - default architecture : x86 - !BOOST_COMP_GNUC : no - BOOST_COMP_GNUC >= 6.0 : no - !BOOST_COMP_CLANG : no - BOOST_COMP_CLANG >= 4.0 : no - Boost.Config Feature Check: cxx14_variable_templates : yes - Boost.Config Feature Check: cxx14_constexpr : yes - !BOOST_COMP_GNUC : no - BOOST_COMP_GNUC >= 6.0 : no - !BOOST_COMP_CLANG : no - BOOST_COMP_CLANG >= 4.0 : no - Boost.Config Feature Check: cxx14_variable_templates : yes - Boost.Config Feature Check: cxx14_constexpr : yes ...found 1 target... Outcome's Jamfile requires: project : requirements [ requires cxx14_variable_templates cxx14_constexpr ] [ predef-require "!BOOST_COMP_GNUC" or "BOOST_COMP_GNUC >= 6.0" ] [ predef-require "!BOOST_COMP_CLANG" or "BOOST_COMP_CLANG >= 4.0" ] <define>BOOST_TEST_MODULE=Outcome <library>../../test/build//boost_unit_test_framework ; So, the fact that !BOOST_COMP_GNUC and !BOOST_COMP_CLANG are false on MSVC is a problem, the tests won't run on MSVC. Yet Outcome works fine for the developer build, as evidenced by the regression matrix. So this is a problem affecting this release build ONLY. Thoughts? Niall
