Re: [Boost-build] Seleting alternatives based on multiple conditions

OK, I separated a simple test case completely outside of my source code 
tree. I believe the only thing that's used from my usual configuration is 
site-config.jam, with the following content:

import toolset : using ;
using msvc : 8.0 ;
using msvc : 7.1 ;
using gcc ;
using como-win ;

I simplified my test case to the point of only distinguishing between 
msvc-7.1 and msvc-8.0, that is, I don't have the additional alternatives for 
<release> or <debug>.

So, in this isolated folder I have a single file, jamroot, with the 
following in it:

lib a : : <toolset>msvc-7.1 <file>a1 ;
lib a : : <toolset>msvc-8.0 <file>a2 ;
exe b : a ;

I launch bjam like so:

bjam variant=release toolset=msvc-7.1 -n

I get this output:

warning: toolset gcc initialization: can't find tool g++

Please let me know if I am doing something wrong.

Thanks,
Emil

This works for me.
Could you give us more detail about your configuration?
