Why does make behave like this?

[Rodrigo de Salvo Braz]

Hi,

This is a make file I wrote, and what happens when I use it:

all: temp/t1 temp/t2
        echo Ok

temp/t%: t%
        mkdir -p temp
        ls > $@

t1:
        ls > t1
        ls > t2

.PHONY: clean
clean:
        rm t1
        rm t2
        rm -R temp

When I run 'make', I get the output:

ls > t1
ls > t2
mkdir -p temp
ls > temp/t1
make: *** No rule to make target `temp/t2', needed by `all'.  Stop.

My question is why do I get this error message? I expected the rule
temp/t%: t%

to be used to make temp/t2.

Thanks,

Rodrigo
