I will do another build on windows with gcc-11.2 with MSys;

``` ...failed updating 5 targets... ...skipped 9 targets... ...updated 8376 targets... ```

Failures are like this ; `...failed msvc.link.dll

Looks like the problem is that you're building 32-bit Boost.Python and linking with 64-bit Python libraries. I'm not sure if Boost.Python is supposed to find the correct libraries or this is just a user configuration error.

Do you mean my configuration mistake; i installed python 3.10 64 bit and checked from MSVC VS 2022 64 bit command line using this ; It looks like my Python is 64 bit;

C:\Program Files\Microsoft Visual Studio\2022\Community> C:\Program Files\Microsoft Visual Studio\2022\Community>python Python 3.10.0 (tags/v3.10.0:b494f59, Oct 4 2021, 19:00:18) [MSC v.1929 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.

import struct version = struct.calcsize("P")*8 print(version) 64

is there a way to configure when building with b2 I used this ; b2 cxxstd=20 --build-type=complete stage

By default both 32 and 64-bit Boost binaries are built. To build only 64-bit binaries you can add address-model=64 to the b2 command line. If you want to build 32-bit libraries, use address-model=32 and also make sure 32-bit Python libraries are found by the build process.

I did another build on Windows 11 ; this time using gcc-11.2 (via MSys2 MinGW), c++20 I did 2 runs one on command line and one on x64 Native Tool MSCV 2022 Also used address-model=64 to avoid Python 32-bit No errors but compiled way less files this time ; typically it was around ~8000+ this time "...updated 3693 targets.." command line i used ; b2 cxxstd=20 address-model=64 toolset=gcc --build-type=complete stage

as usual got warning for auto_ptr and this one ;

C:/msys64/mingw64/include/c++/11.2.0/ext/new_allocator.h:145:26: warning: 'void operator delete(void*, std::size_t)' called on unallocated object 'boost::wave::util::SimpleStringStorage

...

::emptyString_' [-Wfree-nonheap-object] 145 | ::operator delete(__p | ~~~~~~~~~~~~~~~~~^~~~ 146 | #if __cpp_sized_deallocation | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 147 | , __t * sizeof(_Tp) | ~~~~~~~~~~~~~~~~~~~ 148 | #endif | ~~~~~~ 149 | );

If needed I can put the whole build outputs on gist.

This looks like the same issue as https://github.com/boostorg/wave/issues/159. I think it's a new analysis in gcc 11 that we haven't seen before (and therefore not a regression).

Only one question is it normal to use address-model=64 or should this be detected thru b2 or CMake and if it causes any other needed libraries skipped because there was quite a bit of difference in the updated amount
