Re: "argument list too long"

After a few minutes of dependency creation, I get the following error

scripts/mkdep: argument list too long
make: *** [dep-files] Error 2

Can someone help me understand where that comes from?

The error comes from the fact that the  find  command  (the  part  in
`...`  above)  generates a long list of file names which exceeds some
buffer in your shell.

Does it have something to do with the fact that I work under WinXP + Cygwin?

Yes.

No need to say that I am a newbie to the Linux world... help me, Wolfgang
:-)

I try. Find the statement in the Makefile and use xargs  to  avoid  a
long argument list. Something like this might help:

Hi,

Would'nt this overwrite .depend if xargs executes mkdep more than once?
I'd suggest (beware, manually hacked diff ;):
