I want to use Boost Numpy (boost version 1.72) with Visual Studio 2017 and Python 3.8. In my test program which includes I get a link error "boost_numpy38-vc141-mt-gd-x32-1_72.lib". I cannot find the file "boost_numpy38-vc141-mt-gd-x32-1_72.lib" anywhere, it is not created when building the binaries (bootstrap + .\b2) and it is nowhere to be found on the binary repositories at Sourceforge (https://sourceforge.net/projects/boost/files/boost-binaries/ ).
Anybody any clue?
Building Boost using the boostrap + .\b2 method will check to make sure that you have numpy installed before building boost_numpy. Make sure that you have numpy installed (python -m pip install numpy).
On my machine, the exact command used by b2 to check if numpy is installed is:
python -c "import sys; sys.stderr = sys.stdout; import numpy; print(numpy.get_include())"
You can check the command on your own machine by adding --debug-configuration to the .\b2 command, but it should be the same.
Numpy must be installed for whichever version of Python is used for the above command.
Tnx Layne, that was indeed the clue!!
In addition some other clues:
- run 'bootstrap vc141' if you have multiple VS installation and you want to use 2017
- run 'b2.exe --build-type=complete' to get both static and dynamic libraries
Once everything is build you will need
boost_numpy38-vc141-mt-gd-x32-1_72.dll and boost_python38-vc141-mt-gd-x32-1_72.dll to run your program
