Prerequisite target for compiling % wildcard about makefiletutorial HOT 3 CLOSED

You can put bootstrap as a prereq for the default target. Also, boot.txt is an invalid prereq, because there is no target for it.

You also made the unfortunate mistake of using * without the wildcard. See this:

Here's my best guess as to what you want:

default: bootstrap $(wildcard *.in)

boot.txt:
	echo "hi" > boot.txt

bootstrap: boot.txt

# Define a pattern rule that compiles every .in file into a .txt file
%.in: FORCE
	echo $@
	echo $(patsubst %.in,%.txt,$@)

FORCE:

I ended up using the hack with $< which only passes the first parameter.

-%.txt: bootstrap %.in
-        echo $^ $@
+%.txt: %.in bootstrap
+        echo $< $@

Nice! Glad to hear it.
