[comp.lang.c++] Question LEX++ and YACC++

mvvj6@tnofel.fel.tno.nl (Marcel van Veelen) (12/14/90)

I am trying to convert my LEX and YACC files to C++ using LEX++ and YACC++.
However simply using LEX++ and YACC++ gives segmentation faults.
Process starts but crashes somewhere.
Even a very simple language crashes.
Please can somebody tell me what I am doing wrong ?????

You must set the environment variable CCROOTDIR.  See the man page on CC.
