wildcard all the .cc file in the subdirectories?

Hi,

Suppose I have a root directory, whose subdirectories could
also
subdirectories, etc. I want to wildcard all the .cc in the
root
directory, which shall give me all the path of all the .cc
files.
Would you please let me know how to do it?

Thanks,
Peng

  Is this what you're looking for?

DIR:=/path/to/whereever
CC_FILES_IN_ROOT:=$(wildcard $(DIR)/*.cc)


  It doesn't specifically look for files, but as long as
none of your
directories have '.cc' extensions that will be OK.

  Ah, I misunderstood the use of "root directory"
in "all the .cc in the root
directory", but in that case AFAIK the only way to do
it would be

DIR:=/path/to/whereever
CC_FILES_IN_ROOT:=$(shell find $(DIR) -type f -name '*.cc')

(Well, you could actually get horribly tricky with recursive
functions adding
successive instances of '*/' to the front of a string that
start of as '.cc'
and using $(wildcard) on that, but it's probably not worth
the trouble).

I use this function.  Even without the $(info) it probably
requires 3.81.

# logical not
not = $(if $(strip $(1)),,t)

# find-files-matching-extension:
# $(1)=subdir of $(CURDIR) to begin search
# $(2)=extension patterns
# $(3)=private recursive state variable (don't set)
find-files-matching-extension = 
$(strip 
  $(if $(call not,$(3)), 
    $(eval .thisdir := $(CURDIR)/$(1)) 
    , 
    $(eval .thisdir := $(1)) 
   ) 
  $(eval .thesefiles := $(wildcard $(.thisdir)/*)) 
  $(foreach .thisfile,$(.thesefiles), 
    $(eval .subdir := $(wildcard $(.thisfile)/*)) 
    $(if $(.subdir), 
      $(call
find-files-matching-extension,$(.thisfile),$(2),t) 
      , 
      $(filter $(2),$(.thisfile)) 
     ) 
   ) 
 )

$(info $(call find-files-matching-extension,.,%.cc))

   Enjoy
