Re: [Boost-build] How do you redefine features for a variant?

From: Daniel Einspanjer (deinspanjer_at_[hidden])

I added the following to my Jamroot file:
# Rearrange default features to our specs
import feature ;
feature.set-default threading : multi ;
feature.set-default runtime-debugging : off ;
feature.set-default runtime-link : static ;
feature.set-default link : static ;

and if I execute a bjam -d2, I now see /MT in the cl options, but the build 
path is bin/msvc/debug/runtime-debugging-off.
Any idea why that one feature is becoming part of the output path?

p.s. What is the proper name for that propagation of features to the output 
path? I would probably be able to find out more information about 
customizing it if I knew what to search for. :)

This should work with all built-in features. Unless you try to remove NDEBUG
from release, of course...

Yours,
