Hi, I installed Boost 1.68.0 recently from Windows x64 pre-compiled binary "boost_1_68_0-msvc-14.0-64.exe" downloaded from https://urldefense.proofpoint.com/v2/url?u=https-3A__sourceforge.net_projects_boost_files_boost-2Dbinaries_1.68.0_&d=DwIBaQ&c=Ngd-ta5yRYsqeUsEDgxhcqsYYY1Xs5ogLxWPA_2Wlc4&r=uu0095bHyY4u8_4aL_8VSkoBAibccyzY1AWGIZA2kCM&m=cMxoVBp9aAfrFPQFs7HeHNCcnjbvOBsZay8H_qt80Ms&s=Z170hlPZgPTo9kamr5O2JB7PcGOkfoLyrIZ4VPMQ8_U&e=. Then, I noticed that this version of Boost contains only python 3.7 library because the filenames under C:\local\boost_1_68_0\lib64-msvc-14.0 are only boost_python37-vc140-mt-.... This caused errors from building a third-party library which tries to link Boost python 2.7 library (i.e., tries to find file boost_python27-vc140-mt-...) . So what is matter? Does Boost decide to stop supporting python 2.7 since version 1.68.0, or is Boost python 2.7 library located somewhere else using some hard-to-recognize filename? I'm using Windows 10, VS2015 and have only python 2.7 installed. Thank you for your help with this issue.
