How could I generate an output file via a Make rule when the desired content of the file is in a Make variable that's too big for the command line? > and then use redirection to provide the output file to any programs. SET-diff is used to build Make variables which are then used as "lists of targets", so I'd have to use a nested Make invocation :-( > Within Gnu Make, it's pretty easy to $(sort) sort a list, but > de-duplicating it is a bit tougher.

I'll see how/if I can make use of it, thanks, Stefan _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
