Re: Hi everyone,

[Uxio Prego]

Yes of course, by inclusion of headers, in a very much
common way. You can then manipulate shorter *.y and
*.l docs, but this is not going to fix any Bison usage issue
you are having.

If yours is a serious book, it should have made a small
annex stating which versions of Flex and Bison the book
examples are expecting. If it doesn’t, then nothing stops
you from investigating in which years was the book written,
and guessing and eventually figuring out the Flex and
Bison versions used by the examples in it.

If you want an easy quick start, you might consider useful
either to fall back to some other book which would use Yacc
and Lex instead, and then use Bison in Yacc mode until you
know the basics enough to be able to cope with more
advanced contemporary Bison use; or directly fast forward
and use the current Bison and Flex documentation.

Considering you are having some trouble to use Make too,
maybe your case would fit better sticking in C and the Yacc
mode.
