Maximum # of program arguments

Maximum # of program arguments

[Mike Kasprzak]

Hey there,

I'm having problems linking with an ARM targeted GCC cross compiler.  It
looks like I may have hit some sort of limit for number of character or
arguments to an executable (I keep getting "fork" errors, and child cant
find blah blah blah).  I do have quite possibly over 16k characters I'm
passing as arguments to a program.  Whats the maximum, and how can I
increase it?? :).

I'm running the latest (downloaded yesterday) CYGWIN, GCC's (3.1.1 and
2.9.x), MAKE, ...

Any help would be appreciated. :)
Thanks,

I wouldn't have thought that would work even under Unix.

Nor did I think you could increase it.

16k!  Normally one uses a config file well before getting to that
point.  Or provide an option to read input from stdin or something -
like xargs and cpio do ...

Sorry, I know that answer doesn't help.

On WinNT/2K/XP the maximum length of the command line in cygwin is 8K. 
For some reason, it is 256K in Win9X/ME.  Still, you should probably limit
yourself to 8K for maximum portability.

Cheers,
Nicholas
