After installing anaconda3 5.2 I install boost with conda install boost.
In C:\ProgramData\Anaconda3\Library\lib there are two sets of libraries for boost.
boost_python36-vc140-mt-x64-1_67.lib (177 KB)
libboost_python36-vc140-mt-x64-1_67.lib (5576 KB)
what is the difference between these? Is one static and one dynamic?
Refer this link for naming understanding of those libraries.
https://www.boost.org/doc/libs/1_58_0/more/getting_started/windows.html#library-naming
The one started with "lib" is
Prefix: except on Microsoft Windows, every Boost library name begins with this string. On Windows, only ordinary static libraries use the lib prefix; import libraries and DLLs do not.
So it is a static library (libboost_python36-vc140-mt-x64-1_67.lib).
The other one is not with lib prefix, is import library (boost_python36-vc140-mt-x64-1_67.lib ).
Here is a good explanation about import library .
