How to generate rules from two lists ?

[Christophe LYON]

Hi all,

I would like to generate rules from two lists. Currently, I use only one 
list, then I call repetitively a "generating" variable, like in the 
following example:

   deps = gcc binutils newlib

   generate = $(1): $(addprefix $(1)-, $(deps))

   $(call generate, configure)
   $(call generate, all)
   $(call generate, install)

I would like to automatize this process, so I tried this kind of code:

   targets = configure all install
   deps    = gcc binutils newlib

   generate = $(1): $(addprefix $(1)-, $(deps))

   $(foreach target, $(targets), $(call generate, $(target)))

However, the last line is not expanded as I expected (error "multiple 
target patterns").

I *do* understand why (all rules are generated on a single line), but is 
there a way to do what I want? (not especially with the function foreach)


Thanks,

Christophe.
