How did you get just clang.jam to work ? Doesn't it need VC++ support when using clang-cl ?

I installed LLVM 4.0 in C:\LLVM and put

using clang : 4.0 : "C:/LLVM/bin/clang.exe" : <compileflags>-fmsc-version=1910 <linkflags>-fuse-ld=lld ;

in my user-config.jam. It found my VS 2017 installation by itself. There was no need to use the developer command prompt or put anything into PATH.

I'm trying to walk before I can run (but have stumbled :-( )

I:\modular-boost\libs\hello_boost\example\jamfile.v2 just calls run hello_boost.cpp ;

I have pulled Edward's pre-processor update https://github.com/boostorg/preprocessor/commit/dfc1c46ecedef21274eb142e267e...

and tried this in my user_config.jam

with discouraging results.

It picks up the compiler as expected (I think)

notice: will use 'C:/LLVM/bin/clang.exe' for clang-linux, condition <toolset>clang-linux-4.0.0

but doesn't find any targets or do anything beyond config checks???

Performing configuration checks

- 32-bit : no (cached) - 64-bit : yes (cached) - arm : no (cached) - mips1 : no (cached) - power : no (cached) - sparc : no (cached) - x86 : yes (cached) - symlinks supported : yes (cached)

delete I:\modular-boost\bin.v2\libs\hello_boost to check what is created. But there is no expected folders and files here.

But I still only have VS 2015 14.0.25402.00 update 3RC - does this mean I need to update? (Sigh)

Or use a different <compileflags>-fmsc-version=1910 ???

I use -fmsc-version=1900 for VS2015. My entry using the distributed clang 4.0 version, which by default targets VC++, is: using clang : 4.0 : C:/Utilities/LLVM/400/x32/bin/clang++ : <cxxflags>-fmacro-backtrace-limit=0 <cxxflags>-Wno-invalid-token-paste <compileflags>-fmsc-version=1900 <linkflags>-fuse-ld=lld ; and is invoked with "toolset=clang-4.0".

Or am I doing something silly?

But thanks for making progress on this - I still hope to catch up.

PS I would use Cygwin, but I already have mingw installed and changing would muck other things up.
