-ly Yacc library for Linux

I've installed a new version of Suse Linux, but I cant find the -ly library which is nessesary for the gcc compiler to compile the yacc-generated yyparse and my parser.
My Question:
-Is the library on the distribution, but on another directory?
-Is the -ly library in the Internet?

Linux uses bison instead of yacc, usually.
Bison doesn't need a library ;-)

But why gcc doesn't like my parser-routines any more?? In spite of upward-compability there are a lot of warnings and errors.
what is the equivalent for
lex lexfile
yacc yaccfile
gcc parser.c -ly
?

What do you mean  with:
  "gcc doesn't like my parser-routine"
Do you get compiler or linker errors?

lex lexfile       --> flex lexfile
yacc yaccfile     --> bison yaccfile
gcc parser.c -ly  --> gcc parser.c

I assume you have

  #include "lex.yy.c"

in ottersyntax.y , right?
If you combine flex and bison files, you need to have a common header file which defines yytext, for example.
I.g. this will be extracted from your tokens and defines in the .y file with
  bison -d
please refer to  man bison.

I'm not shure about
 > ottersyntax.l:16: stray '\' in program
sounds, that there is a \ which should be quoted.
PLease remove these 2, then compile again.

Flex/bison are much more flexible than lex/yacc. Most names, defines etc. are configurable (of cause most have usefull defaults, but unfortunately these defaults may be the source of you problem).
IMHO, you need to read man-pages (flex and bison). It's hard staff, but once you get used to it, you'll never use lex/yacc again :-)).

Feel free for more questions.
