So I've got one last issue:


The #s between the #### are BOOST_MSVC and _MSVC_VER print outs using the preprocessor just to make sure I know what code is getting compiled.

The warnings can be ignored, they are a very irritating warning that MS spews all the time with dlls and the STL.


It seems to me that the MSVC_VER is high enough that we shouldn't need the workaround, but for whatever reason named_slot_map can't seem to find the right function when it compiles that template.

This code compiles just fine using the 2012 x86 command prompt, (which also is _MSVC_VER=1700) so I'm wondering if there is a header file that has some magic jiggery involving partial template overloading or something and it simply doesn't recognize the combination of _M_ARM and MSVC_VER=1700 or whatnot. I understand if you tell me to go over to boost.iterator's mailing list and ask there....

The problem is that the compiler is expanding to nothing
(thus leaving the .rsp as the first component on the command line).

This indicates that $(cpu-conditions) isn't matching anything.
I'm not sure why.  You might want to add
ECHO cpu-conditions: $(cpu-conditions) ;
before all the toolset.flags calls to check
that it has the expected value.  If that
looks okay, you can try --debug-building
to check the build properties.  (This will generate
a ridiculous amount of output.  You can use
--with-system to limit it to one library)

One problem is that you created a special toolset
version for msvc.  Just use 11.0 as the version
and pass architecture=arm when building.

In summary, what you should have is:

user-config.jam:

using msvc : 11.0 ;

command line:

./b2 toolset=msvc-11.0 architecture=arm link=shared threading=multi
runtime-link=shared variant=debug,release --without-context

(I'm being very explicit here. Some of this can be abbreviated.)
