Hi Steven, 

I realized my mistake; it was an elementary one. I'd used the option "link=static" in my command-line, which would just create an archive of unlinked binary object files instead of checking against the dependencies. Once I changed it to "link=shared", I could see that my link-flags were propagated to the build-system.

Thank you for your response & apologize for wasting your time on a silly matter.

Regards,
Raghu

  Please post specific errors.  These three libraries all require platform specific implementation, so it's entirely possible that they don't support building with windows-api=store.  (Also, assuming that the command line isn't the problem, compile errors would be more appropriate at boost-users.)

I can't reproduce your problem.  After pasting the above into my user-config.jam, I ran:

b2 --with-system link=shared debug -n -a

Looking at the output I see:
link /NOLOGO /INCREMENTAL:NO /DLL /DEBUG /MACHINE:X86 /MANIFEST /subsystem:console /out:"...\boost_system-vc140-mt-gd-1_63.dll"
/IMPLIB:"...\boost_system-vc140-mt-gd-1_63.lib"
"C:/WDK/Lib/winv10.0/um/x64/OneCoreUAP.Lib" /NODEFAULTLIB:kernel32.lib /NODEFAULTLIB:advapi32.lib @"...\boost_system-vc140-mt-gd-1_63.dll.rsp"
which looks right.

What version of Boost are you using?
What command /exactly/ are you using to build?

In Christ,
Steven Watanabe
