Hi guys, Our build-server (Jenkins) tried to build Boost 1.58 with Clang 3.8 and libc++ and tripped over an error that I do not understand. Maybe someone can shed some light on it? The specific error is this: clang-linux.compile.c++.pch /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release/threading-multi/../src/tr1/pch.hpp.pth clang: error: cannot specify -o when generating multiple output files Does this look familiar to anyone? My build-environment is Ubuntu 16.04 x86_64 and I invoked Boost.Build like this: cd /home/jenkins/workspace/Pipeline_Boost/sources/boost_1_58_0 COMMON_COMPILER_FLAGS="-m64 -fpic -fdiagnostics-color=always -O3" CFLAGS="$COMMON_COMPILER_FLAGS" CXXFLAGS="$COMMON_COMPILER_FLAGS -std=c++14 -stdlib=libc++ -isystem/usr/include/libcxxabi -lc++abi" CC=/usr/bin/clang-3.8 CXX=/usr/bin/clang++-3.8 /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost-build/b2 -j1 -q \ --build-dir=/home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost \ --build-type=minimal --layout=versioned address-model=64 install \ --prefix=/home/jenkins/workspace/Pipeline_Boost@3/clang38/installed/opt/BENOCS/clang38 \ --libdir=/home/jenkins/workspace/Pipeline_Boost@3/clang38/installed/opt/BENOCS/clang38/lib/x86_64-linux-gnu \ dll-path==/opt/BENOCS/clang38/lib/x86_64-linux-gnu \ toolset=clang-3.8 \ cflags="$CFLAGS" CXXFLAGS="$CXXFLAGS" linkflags="-Wl,--as-needed" The more detailed error-message is the following: common.mkdir /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build common.mkdir /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8 common.mkdir /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release common.mkdir /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release/threading-multi common.mkdir /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release/threading-multi/.. common.mkdir /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release/threading-multi/../src common.mkdir /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release/threading-multi/../src/tr1 clang-linux.compile.c++.pch /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release/threading-multi/../src/tr1/pch.hpp.pth clang: error: cannot specify -o when generating multiple output files rm -f "/home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release/threading-multi/../src/tr1/pch.hpp.pth" && "clang++" -x c++-header -m64 -fpic -fdiagnostics-color=always -O3 -std=c++14 -stdlib=libc++ -isystem/usr/include/libcxxabi -lc++abi -m64 -fpic -fdiagnostics-color=always -O3 -O3 -Wno-inline -Wall -pthread -fPIC -m64 -m64 -fpic -fdiagnostics-color=always -O3 -std=c++14 -stdlib=libc++ -isystem/usr/include/libcxxabi -lc++abi -m64 -fpic -fdiagnostics-color=always -O3 -DBOOST_ALL_NO_LIB=1 -DBOOST_BUILD_PCH_ENABLED -DBOOST_MATH_TR1_DYN_LINK=1 -DNDEBUG -I"." -I"libs/math/src/tr1" -Xclang -emit-pth -o "/home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release/threading-multi/../src/tr1/pch.hpp.pth" "libs/math/build/../src/tr1/pch.hpp" ...failed clang-linux.compile.c++.pch /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost/boost/bin.v2/libs/math/build/clang-linux-3.8/release/threading-multi/../src/tr1/pch.hpp.pth... ...skipped
