8.3 Lex and Yacc

You may encounter lex and yacc when compiling programs that read configuration files or commands.

  • Lex is a tokenizer that transforms text into numbered tags with labels. The Linux version of lex is named flex . You may need a -ll or -lfl linker flag in conjunction with lex.

  • Yacc is a parser that attempts to read tokens according to a grammar . The GNU parser is bison ; to get yacc compatibility, run bison -y . You may need the -ly linker flag.
