mk file question

In a makefile when you specify something like....

xxx-xx:
-$(yyy) $(zzz)

What does the"-" (hyphen) before the "$" mean? (assuming xxx-xx is the target name)

Hi.
Quote:
To ignore errors in a command line, write a `-' at the beginning of
the line's text (after the initial tab). The `-' is discarded before
the command is passed to the shell for execution.

-- excerpt from iinfo make
If you are starting to use make seriously, I recommend that you read the info file. It is long, but most of your questions will be answered there ... cheers, drl
