hi,

what was an error in your case?
also, what was the boost version? there are many patches for Clang build in
develop not yet released in 1.65.1.
I was able to build with the following config:
=============start===============
using clang : 5.0 :
 "C:/Program Files/LLVM/bin/clang.exe" :
 <compileflags>-fmsc-version=1910
 <compileflags>-DBOOST_USE_WINAPI_VERSION=0x0502
 <compileflags>-DBOOST_USE_WINDOWS_H=1
 <compileflags>-D_WIN32_WINNT=0x0502
 <compileflags>-DNOMINMAX
 <ranlib>"C:/Program Files/LLVM/bin/llvm-ranlib.exe"
 <archiver>"C:/Program Files/LLVM/bin/llvm-ar.exe"
 <linkflags>-fuse-ld=lld ;
==============end===============
