how to add a new compiler switch in bjam

I need to compile a library in managed c++ and looking into msvc.jam, I cannot find any feature that would add the /clr switch to my compile flags.

How would I add such a feature? If possible, I woul开发者_运维问答d like to avoid modifying msvc.jam.

The makefile macro you want for compiler flags is CXXFLAGS, and its equivalent on the bjam command line is cxxflags (lower case):

bjam toolset=msvc cxxflags=/clr
