hi: when I try to compile the dice, there are some errors like this:

I checked the old mailist again. Somebody else encountered the same problem with me. I use g++3.3.6 and bison 1.35. My host OS is ubuntu 5.10. How to fix it?
This looks like something went wrong when translating the scanner.ll files. Could you please check which version of flex/lex you have installed (check the LEX variable in dice/src/parser/dce/Makefile to know which tool is actually used). I am using the '-P' option of flex/lex to replace the "yy" prefix for global symbols and functions (such as yylex()). Seems like this option is not working...
Another problem could be an automake incompatibility. Could you please check the dice/src/parser/dce/Makefile if it contains a LEXCOMPILE variable (which should be set to LEXCOMPILE=$(LEX) $(LFLAGS) $(AM_LFLAGS))? (The AM_LFLAGS variable contains the -P option.)
