[Mesa-users] Being shown yacc help screen when compiling

[Andoru Ekkusu]

So I've been trying to compile llvmpipe using this article:
http://www.mesa3d.org/llvmpipe.html but it gives me this:
________________________________________________________________
  Compiling src/mesa/program/symbol_table.c ...

  Generating build/linux-x86/mesa/program/program_parse.tab.c ...

  -b prefix    Change `y' into `prefix' in all output filenames
  -d           Generate header file `y.tab.h'
  -DNAME       Define btyacc preprocessor variable NAME
  -E           Print preprocessed grammar to stdout
  -l           Do not insert #line directives into generated code
  -r           Write tables to `y.tab.c', code to `y.code.c'
  -S x.skel    Select parser skeleton
  -t           Include debugging code in generated parser
