It is hard to say what is the case. This happens because some error in
the grammar is not detected by the earlier phases in the compiler. In
particular the compiler is trying to process some 'lin' definition for
which there is no definition in the abstract syntax. It could be also
that you forgot to add some abstract syntax module. Try to remove
stuff from the grammar until it start working and then add them back
until you find what exactly caused the problem.
