Dear all, I am experiencing an issue with VS 2017 (15.6.6) while compiling boost.test on my agent. Traces below. I do not recall having applied any change to this agent apart from installing C++/CLI support for CMake people. Is this problem known? Thanks, Raffi build 01-May-2018 11:43:49 D:\bamboo_build_dir\SW-BCB161-VC2017WIN\library\libs\test\test>..\..\..\b2 --abbreviate-paths toolset=msvc-14.1 cxxflags="/std:c++latest" build 01-May-2018 11:43:50 Performing configuration checks build 01-May-2018 11:43:50 build 01-May-2018 11:43:50 - default address-model : 32-bit (cached) build 01-May-2018 11:43:50 - default architecture : x86 (cached) build 01-May-2018 11:43:50 - symlinks supported : no (cached) build 01-May-2018 11:43:50 - junctions supported : yes (cached) build 01-May-2018 11:43:50 - hardlinks supported : yes (cached) build 01-May-2018 11:43:51 - BOOST_COMP_GNUC >= 4.3.0 : no build 01-May-2018 11:43:54 - Boost.Config Feature Check: cxx11_auto_declarations : no build 01-May-2018 11:43:54 - Boost.Config Feature Check: cxx11_function_template_default_args : no build 01-May-2018 11:43:54 - Boost.Config Feature Check: cxx11_lambdas : no build 01-May-2018 11:43:55 - Boost.Config Feature Check: cxx11_hdr_initializer_list : no build 01-May-2018 11:43:55 - Boost.Config Feature Check: cxx11_template_aliases : no build 01-May-2018 11:43:55 - Boost.Config Feature Check: cxx11_decltype : no build 01-May-2018 11:43:55 - Boost.Config Feature Check: cxx11_hdr_random : no build 01-May-2018 11:43:55 - Boost.Config Feature Check: cxx11_hdr_tuple : no build 01-May-2018 11:43:55 - Boost.Config Feature Check: cxx11_variadic_macros : no build 01-May-2018 11:43:55 - Boost.Config Feature Check: cxx11_trailing_result_types : no build 01-May-2018 11:43:56 - Boost.Config Feature Check: cxx11_nullptr : no build 01-May-2018 11:43:56 - Boost.Config Feature Check: cxx11_unified_initialization_syntax : no build 01-May-2018 11:43:56 - Boost.Config Feature Check: cxx11_variadic_templates : no build 01-May-2018 11:43:57 - Boost.Config Feature Check: cxx11_decltype : no build 01-May-2018 11:43:57 - Boost.Config Feature Check: cxx11_hdr_random : no build 01-May-2018 11:43:57 - Boost.Config Feature Check: cxx11_hdr_tuple : no build 01-May-2018 11:43:57 - Boost.Config Feature Check: cxx11_hdr_initializer_list : no build 01-May-2018 11:43:57 - Boost.Config Feature Check: cxx11_variadic_macros : no build 01-May-2018 11:43:57 - Boost.Config Feature Check: cxx11_trailing_result_types : no build 01-May-2018 11:43:57 - Boost.Config Feature Check: cxx11_template_aliases : no build 01-May-2018 11:43:57 ...patience... build 01-May-2018 11:43:57 ...found 3946 targets... build 01-May-2018 11:43:57 ...updating 553 targets... build 01-May-2018 11:43:58 compile-c-c++ ..\..\..\bin.v2\libs\test\test\string_cast-test.test\msvc-14.1\dbg\thrd-mlt\utils-ts\string_cast-test.obj build 01-May-2018 11:43:58 string_cast-test.cpp build 01-May-2018 11:43:58 D:\bamboo_build_dir\SW-BCB161-VC2017WIN\library\boost/config/detail/select_stdlib_config.hpp(18): fatal error C1083: Cannot open include file: 'cstddef': No such file or directory build 01-May-2018 11:43:58 build 01-May-2018 11:43:58 call "..\..\..\bin.v2\standalone\msvc\msvc-14.1\msvc-setup.bat" >nul build 01-May-2018 11:43:58 cl /Zm800 -nologo @"..\..\..\bin.v2\libs\test\test\string_cast-test.test\msvc-14.1\dbg\thrd-mlt\utils-ts\string_cast-test.obj.rsp" build 01-May-2018 11:43:58 build 01-May-2018 11:43:58 ...failed compile-c-c++ ..\..\..\bin.v2\libs\test\test\string_cast-test.test\msvc-14.1\dbg\thrd-mlt\utils-ts\string_cast-test.obj... build 01-May-2018 11:43:58 compile-c-c++ ..\..\..\bin.v2\libs\test\build\msvc-14.1\dbg\lnk-sttc\thrd-mlt\compiler_log_formatter.obj
