Description pavel 2006-06-24 10:08:40 UTC 
Hi,

in the current m173:

In file included from
/disk3/oo/BuildDir/ooo_SRC680_m173_src/rsc/source/parser/rscyacc.cxx:290:
../../unxlngi6.pro/inc/yyrscyacc.cxx: In function `int yyparse()':
../../unxlngi6.pro/inc/yyrscyacc.cxx:2477: warning: label `yyerrlab1' defined
but not used
dmake:  Error code 1, while making '../../unxlngi6.pro/obj/rscyacc.obj'

Comment 1 pavel 2006-06-24 14:32:44 UTC 
I build with

gcc version 3.4.1

(with enum and visibility patches).
Comment 2 jens-heiner.rechtien 2006-06-26 15:37:49 UTC 
Works fine for me (gcc-3.4.1+enum+visibility). Probably it's a bison problem
anyway which produces an unused label. We use bison 1.28.
Comment 3 jens-heiner.rechtien 2006-06-26 15:38:22 UTC 
Reassign to sb for further tracking.
Comment 4 pavel 2006-06-26 16:51:46 UTC 
I use

oo@oo:~> bison --version
bison (GNU Bison) 1.875

and I have used it for 1.1.x and 2.0.x. If this version is not enough, we have
to test that it is not enough. But I doubt it.

The file contaisn this:

/*----------------------------------------------------.
| yyerrlab1 -- error raised explicitly by an action.  |
`----------------------------------------------------*/
yyerrlab1:

  /* Suppress GCC warning that yyerrlab1 is unused when no action
     invokes YYERROR.  */
#if defined (__GNUC_MINOR__) && 2093 <= (__GNUC__ * 1000 + __GNUC_MINOR__) \
    && !defined __cplusplus
  __attribute__ ((__unused__))
#endif
Comment 5 jens-heiner.rechtien 2006-06-26 17:01:11 UTC 
IMHO the solution is to relax that warning=error for generated files. We'll
never be able to test and support all variants of yacc/bison etc.
Comment 6 Stephan Bergmann 2006-06-27 09:01:41 UTC 
I second HRs last comment.  Meanwhile, I encountered the same problem on my home
OOo build, and this issue will be fixed as part of issue 66577:
