ifeq problem?

[S Tao]

Hi, I wrote a make target "test-test" as below. my intention is to assign 1/2 
to v1/v2 respectively.  However, when I run command "make test-test", I am 
getting "v1 == v2". Why? What workaround is available to achieve what I want to 
do here? Thank you very much for your helps.

test-test:
    $(eval v1=$(shell sh -c "echo 1"))
    $(eval v2=$(shell sh -c "echo 2"))
    @echo "v1=$(strip $(v1))="
    @echo "v2=$(strip $(v2))="
ifeq ("$(strip $(v1))", "$(strip $(v2))")
    @echo "v1 == v2"
endif
.PHONY: test-test
