Maybe a Bison version issue. Which Bison version are you using?
The C arrays yyprhs[] and yyrhs[] are automatically generated by Bison
according to the current grammar definition in src/network/lscp.y. However
there is something special about them: those two arrays are not required for
Bison's basic parser work, they are rather intended to be used for debugging
purposes, human readable syntax errors, custom parser code and stuff like
that. That's why those two arrays are embedded into C preprocessor macros in
the auto generated lscpparser.cpp file by Bison. In my Bison version I just
had to add
#define YYDEBUG 1
to make those arrays available (I added this define in lscpparser.h). Does
your Bison version need another macro maybe?
