[Cook] How can I make my cook file stop always generatingdependency files? -- LONG --

[Pendergraft, Jerry]

I believe your problem is due to a couple simple things:
1) 	#include-cooked [pkg_dependencies]  should be:
	#include-cooked-nowarn [pkg_dependencies]
2) On the dep file recipes
    set no-cascade  should be
  set nocascade

There are also some simplifications you could easily do.
First you don't need 2 recipes for the dep files. You can combine them into one using another pattern match. The following would work for both .cpp .hpp plus .hxx .C .c or anything.

%0%.%1_dep: %0%.%1
  set nocascade
{
  function Say-Why [__FILE__] [__LINE__];
  c_incl --no-cache --no-recurs %0%.%1
    -I[dirname %0%.%1]  [cpp_incl]
    "--prefix='cascade %0%.%1 = '"
    "--suffix=';'"
    -o [target]
      set silent;
}

Second your loop where you define the variables could be:
/* turn the list of packages into a list of libraries */
loop local var_name = [pkg_names]
{
  local var_lib = [prepost lib/lib .a [var_name]];
  [var_lib]_src = [match_mask [var_name]/%0%.cpp [MANIFEST]];
  [var_lib]_hdr = [match_mask [var_name]/%0%.hpp [MANIFEST]];
  [var_lib]_xml = [match_mask [var_name]/%0%.xml [MANIFEST]];
  [var_lib]_obj = [fromto %0%.cpp %0%.o       [[var_lib]_src]];
  [var_lib]_dep = [addsuffix _dep [[var_lib]_src]] [[var_lib]_hdr]];
                  ;
  function print [var_lib]_src is [[var_lib]_src];
  function print [var_lib]_dep is [[var_lib]_dep];

  if [count [[var_lib]_obj]] then
  {
    pkg_libraries          += [var_lib];
    pkg_dependencies  += [[var_lib]_dep];
  }
}

I'm trying to create a cook book based on the sample that uses dependency files in the user's guide. I've got it working, but there are a few things that I don't understand. The cook file is attached, it's long but I don't know which parts to cut out and still make it understandable.

1. When I run a "cook what" to create a dump of my variables so that I can verify what I'm doing, it always re-creates all of my _dep files. I'm pretty sure it's because of this line
	#include-cooked [pkg_dependencies]
Is there a way to make that conditional?

2. The sample had the cpp_dep files created with "set no-cascade" and the hpp_dep files created without that. I've tried it both ways and it seems to work, so I guess that I'm not understanding what it is that the no-cascade option does. I've looked at the manual but remain utterly clueless.

3. Why does the hpp_dep rule look at dirname %0%.cpp? Shouldn't it look at %0%.hpp or since it's doing a dirname, does it even matter?
