Hi Everyone,

I`m developing application for Windows 10 phones and I`d like to use Boost
in it.
I`ve tried to build current release (1.59.0) to support UWP but currently
with no major success.

Using command:
 b2.exe toolset=msvc-14.0 link=static windows-api=store threading=multi
runtime-link=shared

results in errors like:

libs\filesystem\src\operations.cpp(178): error C2039:
'GetEnvironmentVariableW': is not a member of '`global namespace''
libs\filesystem\src\operations.cpp(178): error C3861:
'GetEnvironmentVariableW': identifier not found
libs\filesystem\src\operations.cpp(182): error C2039:
'GetEnvironmentVariableW': is not a member of '`global namespace''

Which I think is due to using API not supported in UWP.

When I tried using header-only portion and I discovered that setting  flag
/ZW (https://msdn.microsoft.com/en-us/library/hh561383.aspx) resolves this
issue ( I successfully compiled some of asio examples) so I`ve tried to
pass this flag when compiling with b2.

 b2.exe -a  -d+2  toolset=msvc-14.0 link=static windows-api=store
threading=multi runtime-link=shared cxxflags=/ZW

But it yields errors like libs\graph\src\read_graphviz_new.cpp: fatal error
C1107: could not find assembly 'platform.winmd': please specify the
assembly search path using /AI or by setting the LIBPATH environment
variable

So i looked for mentioned file location and tried to use
using msvc : : :
<compileflags>/ZW
<compileflags>/AI"\"C:/Program Files (x86)/Microsoft Visual Studio
14.0/VC/lib/store/references/\""
;

with b2.exe -a  -d+2  toolset=msvc-14.0 link=static windows-api=store
threading=multi runtime-link=shared

Some libraries compile, but others yields errors like:
libs\filesystem\src\operations.cpp(178): error C2039:
'GetEnvironmentVariableW': is not a member of '`global namespace''

and

libs\context\src\execution_context.cpp(24): error C2483:
'boost::context::execution_context::activation_record::toplevel_rec':
object with destructor or non-aggregate type cannot be declared with thread
storage duration in WinRT code

I experimented with vcvars scripst and i discovered that passing "store" to
script sets some variables in promising way, but i couldn't make b2 to pass
this argument, I`ve  tried to use <setup> and <setup-x86> in my
user-config.jam but with no success. It always used the scrip from <setup>
and passed argument "x86".

Could you provide me with some guidelines how to compile and use Boost with
Windows Universal Platform, or any other way to use Boost with Windows 10
phones?

Best regards
