Re: A function to print instead of $(warning ) or $(error )

[Pete Johnson]

I finally settled on this solution to printing a message. The drawbacks 
are that it spawns a process for each call, and the output goes to 
stderr. It does however handle tabs quotes multiple newlines without 
problems. There are some quoting issues (mostly with \) but users just 
typing in most text will not get surprised.

define newline


endif

output-message = $(shell printf "$(subst $(newline),\n,$(subst 
",\",$1))\n" 1>&2)

Thanks for all your help.
