This is a bug, which has been fixed for the next release: https://savannah.gnu.org/bugs/?61463 In the meantime it will work to separate the export from the private, like this: FOR_FOO := global foo: private export FOR_FOO = $(p_FOO) foo: private p_FOO := 1 foo: bar baz foo bar baz: ; @echo $@: $$FOR_FOO (the "private" on the first foo: line doesn't have the desired effect until the above bug is fixed but I left it there anyway). Note it's of course critically important to use "=" in the export assignment, not ":=".
