Windows Boost 1.64 VS2017 Python libraries are missing

I am trying to build Boost 1.64 on Windows with VS2017. Everything builds without errors, but some s .lib

and .dll

s are missing in my output libs directory . Specifically, the main missing library I need is Boost.Python.

My last attempt at creation looks like this, although I've tried many different combinations of options:

.\b2 --prefix=c:\boost --build-dir=boost_build --layout=versioned toolset=msvc-14.1 address-model=64 -j4 --with-python -a --reconfigure --stage-dir=stage --build-type=complete --debug-configuration -d2 stage >build.log 2>&1

      

        
        
        
      

    

And my build output looks like this:

...found 1 target...

      

        
        
        
      

    

Notes:

• I am using Miniconda instead of a traditional Python installation. Could be a problem, although the output from it --debug-configuration
  
  definitely indicates that it is finding everything correctly.
• After adding some debug messages, I found that what I found 1 target
  
  is all
  
  target; I don't see any build results for boost.python sources, as I see if I build additional libraries.
• Adding additional debug output isn't particularly useful; even with maximum debugging results, I could not find any Python related errors or warnings.
• I also tried starting with boost.python quickstart , which compiles successfully but is not linked because it cannot find it boost_python.dll
  
  . (Although technically I think it should be looking for something like boost_python-vc141-mt-1_64.dll
  
  ...)

I tried several options for combinations bootstrap.bat

(eg, --with-libraries=python

, --with-python=C:\Miniconda2\python.exe

, --with-python-root=C:\Miniconda2

), and b2.exe

, but it seems that nothing has changed.

If I download the pre-compiled libraries boost_python

and put them along with all the other libraries I have created, my project builds and works as expected. Building the python libraries themselves is the only thing I still stick with.

I know that I am not alone; I posted this question on a Reddit thread and another user mentioned that they have the same problem; unfortunately his solution was to "end up hitting the right set of options for both bootstrap and b2".

Does anyone else have a problem like this?
