im offically confused now i can't build any of my former projects using 1.73 or 1.74 only 1.69 works without changes (maybe also 1.70+) so mabye i didn't properbly checked the builds when i upgraded to 1.73 IDE: VS2017, clang-cl 10.0.0, LLVM Visual Studio Extension, Boost 1.69,1.73,1.74 - freshly build using Boost 1.69 projects builds with microsoft-cl and clang-cl without definining BOOST_LIB_TOOLSET for Boost 1.73,1.74 i need to set BOOST_LIB_TOOLSET to "vc141" example: ---------------------- //#define BOOST_LIB_TOOLSET "vc141" // only needed for 1.73 and 1.74, not for 1.69 #include <boost/regex.hpp> /* definition to expand macro then apply to pragma message */ #define VALUE_TO_STRING(x) #x #define VALUE(x) VALUE_TO_STRING(x) #define VAR_NAME_VALUE(var) #var "=" VALUE(var) #ifdef _MSC_VER #pragma message(VAR_NAME_VALUE(_MSC_VER)) #pragma message(VAR_NAME_VALUE(_MSC_FULL_VER)) #endif #ifdef _clang__ #pragma message(VAR_NAME_VALUE(__clang__)) #pragma message(VAR_NAME_VALUE(__clang_version__)) #endif #ifdef BOOST_MSVC #pragma message(VAR_NAME_VALUE(BOOST_MSVC)) #endif #ifdef BOOST_VERSION #pragma message(VAR_NAME_VALUE(BOOST_VERSION)) #endif #ifdef BOOST_LIB_TOOLSET #pragma message(VAR_NAME_VALUE(BOOST_LIB_TOOLSET)) #endif int main() { return 0;

i've never need to change anything in my projects beside installing latest LLVM/clang + extension and switching the compiler in every of my private and customer projects - its the first time with 1.74 that it does not work out of the box
i've never set any auto-link defines and using clang-cl on daily basis for some years now
What happens when you define BOOST_LIB_DIAGNOSTIC? What's the full compiler output when building your test program?
