Possible to output line Makefile is executing?

Is it possible to output the line a Makefile is executing? I'm getting this "No rule to make target X needed by Y" and I want to know where in the Makefile it's trying to call this rule.

I can't locate a means of outputting the executing line number of a Makefile (this certainly doesn't mean there's no way to do it) but this may help:

shell# make --debug=v

It doesn't return line numbers, but gives verbose output as to what file Make is reading, what it decides to do with what it reads, and more.

If you need to run something like `make helloworld` then just put the 'helloworld' after the --debug=v

The `Make` man page has more details & other options.

Hope this helps some,

Sasha

If you wrote the 'Makefile', I guess you will
have an idea, what it is about.

If we are talking about a standard application,
please tell which.
And which Linux is used for the compilation ? ?

... Not to be found in the Makefile, it is a
"build in" function / reply in the 'make' executable.

This command will give a reply ( with a linenumber )
if the word is in the Makefile :

cat -n Makefile | grep -i <word>
