Also read up on 'Command Execution'. If you want to avoid that each command is executed by a new shell, try this
%.foo : %.bar: baz $*.spam ; spam $*.eggs > $@ or %.foo : %.bar: baz $*.spam && spam $*.eggs > $@ I sometime need the makefile to create intermediate scripts; here's a simple way to do that: %.foo : %.bar: ( echo "baz $*.spam" ; echo "spam $*.eggs" > $@ kind regards Peter Ring -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Peter Ring Sent: 29. november 2002 10:14 To: Jens Schweikhardt; [EMAIL PROTECTED] Subject: RE: Here Documents in commands Read up on 'Defining Variables Verbatim', the define directive. Using define, you can assign a multi-line value to a variable. This multi-line variable can of course contain references to variables that will get expanded when you reference the multi-line variable. Bingo, you've got a multi-line template. Kind regards Peter Ring -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jens Schweikhardt Sent: 28. november 2002 20:36 To: [EMAIL PROTECTED] Subject: Here Documents in commands hello, world\n I've been thinking long and deep and even made a few attempts at using shell "here documents" in the commands for a rule. My conclusion is that it is impossible, at least with a POSIX shell. Make's command execution with sh is inherently line oriented, while here documents are multi-line by definition. Continuing lines in the Makefile with backslash newline can't work because the shell only sees the resulting single line. In the remote event that I have overlooked something, does anyone know a way how to get something like cat << EOF foo bar EOF in a rule? PS: Yes, I can get the same effect with a fews echos. Consider it a proof-of-concept question.
