Re: [solution] how to vary library path based on toolset version

Could some of the several people using BBv2 please pitch in to help
this guy out? I hardly ever use it, so the answers don't come easily
to me!

Definitely the wrong way to go about this. There are conditional
properties. You want something like

lib fooLib
: 
: <name>fooLibd 
<toolset>msvc-7.1:<search>z:/lib/vc7/mt
<toolset>msvc-6:<search>z:/lib/vc6/mt
<toolset>msvc 
<variant>debug
;

Though it might turn out to be a bit uglier:

lib fooLib
: 
: <name>fooLibd 
<toolset>msvc/<toolset-version>7.1:<search>z:/lib/vc7/mt
<toolset>msvc/<toolset-version>6:<search>z:/lib/vc6/mt
<toolset>msvc 
<variant>debug
;

Though as long as msvc is a *requirement*, maybe

lib fooLib
: 
: <name>fooLibd 
<toolset-version>7.1:<search>z:/lib/vc7/mt
<toolset-version>6:<search>z:/lib/vc6/mt
<toolset>msvc 
<variant>debug
;

is enough.

P.S. We like to know the names of the people with whom we're
conversing, if you don't mind. Since you call yourself "RubyScript"
elsewhere, I assume "Altec" is a pseudonym.
