Undefined reference to yyparse (flex & bison)

Question

I\'m attempting to learn some flex/bison, and I\'m reading Flex & Bison by John Levine (O\'Reilly). There is an example that I need to get running, however I can\'t get it

Answer 1

I read that chapter as well and I believe the author is indicating that the code should be put in a "Makefile" to automate the build process for said files.

The $@ is a variable expansion used in bash shell scripts (among other places) and probably does the same thing in make or is exactly the same thing that make is implementing.

Answer 2

Solved it, the command

cc -o $@ fb3-1.tab.c fb3-1.lex.c fb3-1funcs.c

Should be

cc -o fb3 fb3-1.tab.c fb3-1.lex.c fb3-1funcs.c

Not sure why the book didn't specify that for the example.
