I'd guess that the define makes the binding available at run time and thus include comes "too early" (i.e. compile time): the variable somehow already exists as far as include can see but has no value... I don't know whether it is TRT, but you might try wrapping your define form in (eval-when (compile) ...) or similar. But see the doc of eval-when, especially if you have any cats. Cheers -- t
