But seriously though: why is that not caught by check-package? Because it is not actually an override: the variable is not yet set there, so it is valid to unconditionally set it. check-package should probably recognise that the variable is <FOO>_DEPENDENCIES and consider that conditional assignment should still be forbidden in that case.

I had a look at this, and it is not entirely trivial to test for in check-package. Basically, this is allowed: ifeq(...) FOO_VAR = ... endif ... $(FOO_VAR) ... # Empty if condition not true And this as well: ifeq(...) FOO_VAR = ... else FOO_VAR = ... endif But this is not: ifeq(...) FOO_VAR = ... endif ifeq(...) FOO_VAR = ... endif So basically: - after a variable is assigned, it can't be assigned to any more in the same conditional branch; - it can be assigned to again in the else branch (including else ifeq constructs); - it can not be assigned to any more after the endif. In addition, conditions can be nested... The only way I can think of implementing this is by keeping a stack of conditionally assigned variables. In the else branch, the top of the stack is saved en empties. At the endif, the top of the stack is popped, merged with the saved one, and merged into the new top of the stack. Wow, by writing it down, I almost implemented it :-) Let's see if I can still find the time to actually do it tonight...

Sorry, but I think I got lost somewhere... Currently, check-package does not whine for: ifeq(...) FOO_VAR = ... endif but it does whine for: FOO_VAR = ... ifeq(...) FOO_VAR = ... endif And these two behaviours are, I think, correct. What I am arguing, is that FOO_DEPENDENCIES should be treated specially, where check-package should whine for: ifeq(...) FOO_DEPENDENCIES = ... endif as well as for: FOO_DEPENDENCIES = ... ifeq(...) FOO_DEPENDENCIES = ... endif Regards, Yann E.

My "wanted behaviour" was for other variables which can have the same problem. Probably doesn't happen very often though.
