I was hoping to start running regression tests for the upcoming Visual Studio 2019 (toolset 14.2) and got stumped by an issue. I've set a user-config.jam: using msvc : 14.2 ; using python : 2.7 # version : C:\\Python27-32\\python.exe # Interperter/path to dir : C:\\Python27-32\\include # includes : C:\\Python27-32\\libs # libs : <address-model>32 <address-model> # conditions ; using python : 2.7 # version : C:\\Python27-64\\python.exe # Interperter/path to dir : C:\\Python27-64\\include # includes : C:\\Python27-64\\libs # libs : <address-model>64 # conditions ; Then I ran the command, from a vs2019 developer command prompt: D:\tmp>C:\Python27-64\python.exe run.py --runner=teeks99-test02 --toolsets=msvc-14.2 --tag=develop The full build output (minus some repetitive git and mklink commands) can be found here: https://gist.github.com/teeks99/2d72382bf13569855dbdcd2e0850c1cf A couple notable parts...
