Hi Tina, When you build the boost libraries, is there a way to generate .lib files for them? Below, I have documented the steps I took to build the library. Please take a glance at it and let me know if I missed something that will allow me to obtain the .lib file. I cannot see your pictures („A non-text attachment was scrubbed...“), so I can only guess what goes wrong. My way building boost is (on Windows with VC++ 2015) cd c:\boost_1_64_0 .\bootstrap .\b2 --without-mpi --without-python --build-type=complete --reconfigure msvc stage This generates library files, for example libboost_serialization-vc140-mt-1_64.lib in the stage subdirectory of my boost root directory, here c:\boost_1_64_0\stage __________________________________ Freundliche Grüße * Best regards * Met vriendelijke groeten * Meilleures salutations Holger Gerth _________________________________________________________________________________ EB-Soft Gesellschaft fuer elektronische Beschriftungs-Software mbH Neckargartacher Str. 114, 74080 Heilbronn, Germany Tel: +49 (0)7131 / 9466-0 Email: info@ebsoft.de Fax: +49 (0)7131 / 1099-0 Homepage: www.ebsoft.de Amtsgericht-Registergericht-Stuttgart HRB 102882 Geschaeftsfuehrer: Michael Ehring, Helmut Sigler _________________________________________________________________________________
