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.
