Re: BBv2 and globbing

Hi,

I have found a hack solution to the globbing problem:

I added to the file boost/tools/build/v2/build/project.jam the following code

# This module defines rules common to all projects
module project-rules
{
....
rule globex ( subdir wildcards + )
{
import path ;
import project ;

local location = [ project.attribute $(__name__) location ] ;
local all-paths = [ path.glob $(location)/$(subdir) : $(wildcards) ] ;

return $(all-paths:D="") ;
}
}

and called it in my jamfile this way:

lib system : [ globex src *.cxx ] : <include>inc ;

This works fine but I would prefere a solution using the predefined glob rule 
in the way Dave Abrahams suggested.

If such a solution does not exists is it possible to add a rule like globexto
project.jam?

Any suggestions?

With best regards

Johannes
