RE: Advice on "clean:" rule for Win32 platform needed...

[Bijal Shah]

There is a very specific limit of around 4096 characters in Windows NT. I
think this is much less in Windows 95 and I don't know about Win2k.

I ran into the very same problem and had to resort to some ugly code to make
it work - I seem to remember using $words or similar to split the request
over several "batches", or in one case writing a console program in C to do
the job for me.

I tried all sorts of tricks and couldn't get around the character limit - it
gets you somewhere.

B.

P.S. Also worth watching out for is the behaviour of the 'for' command for
files - its different between different NT service packs.

Then what about using the other trick I suggested (with wildcards)?

Win2k?

There should be no limits, at least not limits that you should hit in 
your scenario.  I suspect that your commands use shell features, and so 
Make goes through a temporary batch file to run those commands.  Batch 
files is where the limits bite you.

So a solution would be to avoid using shell commands entirely; then Make 
should attempt to invoke the command directly, not via the shell.

In other words, throw together a simple version of `rm', compile it with 
the Windows compiler, and use it (with an explicit list of files to 
delete, not via a FOR loop) to remove those files.
