What toolset did you use?
What does your user-config.jam file look like?
Do you run bjam/b2 from the Windows command line or the bash command line?
I do not use cygwin, however I have successfully been building and using Boost with Clang on Windows using the toolchain provided by rubenvb over at the Mingw-w64 project: http://sourceforge.net/projects/mingw- w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/rubenvb/cl ang-3.1-release/
My user-config.jam is empty.
I compile with the following command line (windows command line):
set OLDCD=%CD% pushd %BOOST_ROOT% set OLDPATH=%PATH% set PATH=%MINGW32_CLANG%;%MINGW32_CLANG%\bin\;%PATH% b2 -j %NUMBER_OF_PROCESSORS% toolset=clang cxxflags=-std=c++11 address-model=32 architecture=x86 --stagedir=stage/clang-x86 link=static runtime-link=static threading=multi debug-symbols=on define=WINVER=_WIN32_WINNT_VISTA define=_WIN32_WINNT=_WIN32_WINNT_VISTA stage > %OLDCD%\clang32.txt set PATH=%OLDPATH% popd
Unfortunately Boost is detecting the compiler as "clang.linux", but other than that it seems to work for the most part.
The stuff that doesn't work: * Boost.Context (it fails to assemble its assembler files) * Boost.Math (it attempts an 'rm' command, I assume because it thinks it's on *nix) * Boost.Python (the same ::hypot error that also plagues GCC in C++11 mode)
Most everything else seems to work okay (though I have to use pragmas to disable a LOT of warnings when including boost headers, though that may simply be because I have all warnings enabled).
Clang support on Windows still needs a lot of work (Ruben tells me that there's about half a person working on it on the Clang side), but perhaps some interest from the Boost community would help drive some more investment into the platform?
This sounds rather promising.
Having got Ruben's mingw gcc binary to work nicely with NetBeans, I tried to use Ruben's Clang binary, but I haven't got this configured right yet. Since NetBeans provides a nice IDE on Windows, I'm sure there will be lots of enthusiasm from Boosters to be able to use this compiler.
But I am now trying to build the Boost libraries using the mingw. After some googling, I've added # Clang compiler using mingw32 dw2 Ruben's release. using clang : 3.1 : "C:/mingw32-dw2/bin/clang++.exe" : # <cxxflags>-std="c++11" <cxxflags>-v # diagnostics <cflags>-nostdinc # Do not include MSVC C headers. <cxxflags>-nostdinc++ # Do not include MSVC C++ headers. # Instead use mingw-dw2 for includes <cxxflags>-cxx-include-arch="C:/mingw32-dw2/i686-w64-mingw32" <cxxflags>-cxx-include-root="C:/mingw32-dw2/include/c++/4.6.3" <cxxflags>-cxx-include-32bit-dir=32 <cxxflags>-stdlib=libc++ <linkflags>-stdlib=libc++ ; # includes like <cstddef.h> are at C:\mingw32-dw2\include\c++\4.6.3 to my user_config.jam with this results compile.c++.without-pth i:\boost-trunk\boost\bin.v2\libs\test\build\clang-linux-3.1\debug\threading-multi\execution_monitor. obj clang version 3.1 (tags/RELEASE_31/final 161181) (llvm/tags/RELEASE_31/final 161243) Target: i686-w64-mingw32 Thread model: posix "C:/mingw32-dw2/bin/clang++.exe" -cc1 -triple i686-w64-mingw32 -S -disable-free -disable-llvm-verifier -main-file-name execution_monitor.cpp -mrelocation-model static -mdisable-fp-elim -mconstructor-aliases -target-cpu pentium4 -target-linker-version 2.22.0.20120323 -momit-leaf-frame-pointer -v -g -coverage-file C:/Users/Paul/AppData/Local/Temp/execution_monitor-536331.s -nostdinc++ -resource-dir "C:/mingw32-dw2/bin\\..\\lib\\clang\\3.1" -D BOOST_ALL_NO_LIB=1 -D BOOST_TEST_DYN_LINK=1 -I . -fmodule-cache-path "C:\\Users\\Paul\\AppData\\Local\\Temp\\clang-module-cache" -stdlib=libc++ -O0 -Wall -pedantic -fdeprecated-macro -fno-dwarf-directory-asm -ferror-limit 19 -fmessage-length 0 -mstackrealign -fno-use-cxa-atexit -fno-inline -fgnu-runtime -fobjc-runtime-has-arc -fobjc-runtime-has-weak -fobjc-fragile-abi -fcxx-exceptions -fexceptions -fdiagnostics-show-option -o C:/Users/Paul/AppData/Local/Temp/execution_monitor-536331.s -x c++ "libs\\test\\src\\execution_monitor.cpp" clang -cc1 version 3.1 based upon LLVM 3.1 default target i686-w64-mingw32 ignoring nonexistent directory "/usr/local/include" ignoring nonexistent directory "C:/mingw32-dw2/bin/../lib/clang/3.1/../../../x86_64-w64-mingw32/include" ignoring nonexistent directory "/mingw/include" ignoring nonexistent directory "/usr/include" #include "..." search starts here: #include <...> search starts here: .
