c++ - makedep redirect to file

Hi,

I can't get makedep to write to a file.  In the docs, the following
technique is suggested:

    makedep -s sourcefile.cpp > outfile.dep

but when I try this, the '>' is treated as a file to create dependancies
for.  As is 'outfile.dep'.

Without redirection, how (and where) would this utility be used in the
makefile?  I've tried numerous things but usually I get the error:

    missing { Colon Colon2 } in target block

Sorry, I replied personnally and not to the group by mistake.

No.  Makedep then thinks that '>outfile.dep' is a file to create
dependancies for.

I should have mentioned it's WinME.

I've tried all the variations I can think of for the cmdline, but no joy.
Besides, redirection works ok with other programs.

Does anyone else have the same problem?  Or to put it another way, does
EVERYONE else NOT have this problem?

ah... well i have heard that WinME has some strange behavior.  wish i could
help, i'm sure there is a solution.  so if you try:  
dmc > output
you create a file named output, but it doesn't work with makedep?  if it's just
that one app, i'd say it's likely a makedep bug.  if it's the whole range of dmc
apps i'd say the os is possibly at fault...

weird!

if it turns out to be an os issue, here's a pretty large forum on winme you
might find some help there...

Just to bring you up to speed, I now have makedep working and it turns out
that my problem is nothing to do with makedep, but the way I've been trying
to use it in the makefile.  After alot of water under the bridge, this is
where I stand now:-

    target.exe : $(ALLOBJ:.obj=.dep) $(ALLOBJ) etc...
        dmc blah...

    .cpp.dep:
        makedep -s $*.cpp >$*.dep

This is basically what I'm trying to do in order to automatically update the
dependancies.  The problem is that the exts are not substituted in the
macros so the implicit rule to build the dep files is never used.

The docs for smake say that this should work.  Any Ideas?

hmmm, well i'm not real good with smake, but you can make one file with all the
dependencies like this:

*.dep:
makedep -s $*.cpp >all.dep

if you want to make separate files for each .cpp maybe you can make a macro that
is a wildcard?  i don't think $* should expand, cuz it's not a macro?

there's always a way, long as ya don't give up!

With this method, every time one file needs updating, the dependancies of
all files are updated.  With very large projects, this could take some time.

It actually expands to the current target's name and path, without the
extension.  (Look in the smake docs).

At the moment I can see only 2 options
    1. Use a different make (MinGW, Borland, etc...).
    2. Create a $(ALLDEP) macro when creating the makefile.

The first option is definately out.  I want to solve the problem using only
tools available in the DM downloads.

The second option means I will have to re-write a section of my IDE in order
to support this (pain in the neck, but possible).

I really would like to know of any other options that have eluded me.

didn't realize that, good to know!  seems like as with c/c++ that make file
programming can be frustrating sometimes... good luck.
