Research direction

Start in src/contrib/boost.jam at the tag_versioned rule referenced by the issue. Reproduce the report with b2 architecture=x86 address-model=64 and inspect the generated MSVC library name. Done means the x64 build requests the architecture-qualified library and completes successfully.

Written by the indexing model from the issue text.

Description

I use b2 to compile a simple example, and got an error with msvc/Windows:

$ b2
...patience...
...found 817 targets...
...updating 1 target...
msvc.link bin\msvc-14.2\release\cxxstd-latest-iso\threading-multi\test_boost.exe
LINK : fatal error LNK1181: cannot open input file 'boost_program_options-vc142-mt-1_76.lib'

        call "bin\standalone\msvc\msvc-14.2\msvc-setup.bat"  >nul

...failed msvc.link bin\msvc-14.2\release\cxxstd-latest-iso\threading-multi\test_boost.exe...
...failed updating 1 target...

The file boost_program_options-vc142-mt-1_76.lib should be boost_program_options-vc142-mt-x64-1_76.lib.

After looking up boost.jam, I think on Windows this should be:

rule tag_versioned ( name : type ? : property-set )
{
    return [ common.format-name <base> <toolset> <threading> <runtime> <arch-and-model>
        -$(.version_tag) -$(.build_id) : $(name) : $(type) : $(property-set) ] ;
}

After adding , b2 architecture=x86 address-model=64 succeeded.
