Hello, I have a project like this
  root
    |
    +- dir1
    |
    +- dir2
    |
    `- inc
dir1 and dir2 contains .c source files and .h headers
I want to create rule that create symbolic links to headers files in
dir1 and dir2 into inc (only for unix)
I tried to do something like this:
Jamfile at root/inc:
----
import path ;
rule header-link ( dirs * )
{
  if ! $(NT)
    {
      for local d in $(dirs)
        {
          for local h in [ GLOB [ path.join $(GBLA_ROOT) $(d) ] : *.h ]
            {
              ECHO $(h) ;
              # here i want to 'ln -s $(h) .' ;
            }
        }
    }
}
header-link dir1 dir2 ;
----
project-root.jam at root :
----
path-constant GBLA_ROOT : . ;
import toolset : using ;
import gcc ;
----
but I can not do something similar to:
ln -s $(h) .
Is there a way to do it?
best regards,
Jorge
