Hi, I tried to recompile Alliance 3.0 on a Solaris 2.5 x86 machine but keep getting error messages from the parser (yacc and bison) when trying to parse parser.yac file. Is this something known to cause problems or am I doing something wrong. Thanks, ilic@hickory.engr.utk.edu P.S. Here is an error message: make[1]: Entering directory `/opt/pkg/alliance/tools/mbkedif/archi/solaris/obj' /opt/Summertime_97.i386/bin/bison -y -d parser.yac ("parser.yac", line 343) error: empty rule for typed nonterminal, and no action ("parser.yac", line 1005) error: empty rule for typed nonterminal, and no action make[1]: *** [parser_yac.o] Error 1 make[1]: Leaving directory `/opt/pkg/alliance/tools/mbkedif/archi/solaris/obj' make: *** [mbkedif] Error 2
