Re: [Boost-build] Simple bjam question: linking in boost libraries?

Thanks so much for your help. I put the using darwin : 3.2 :
/Users/lally/Work/bin/gfilt ; line into ~/user-config.jam, and it did
exactly what you said.  Wonderfully formatted warnings, and ld's not
complaining about unknown flags anymore.

But, it's not linking in the libraries.  I'm sorry.
bjam eventually runs:

    /Users/lally/Work/bin/gfilt  -o "bin/darwin-3.2/debug/mfront"
"bin/darwin-3.2/debug/config.o" "bin/darwin-3.2/debug/driver.o"
"bin/darwin-3.2/debug/output.o" "bin/darwin-3.2/debug/main.o"
"bin/darwin-3.2/debug/map.o" "bin/darwin-3.2/debug/actions.o"
"bin/darwin-3.2/debug/generator.o"     -g

which complains about many, many undefined symbols.

Is there any other means of specifying a library to link in?
