Patch to fix warnings because of redundant declarations

Bison did some API changes. Gst does not build:

grammar.tab.c: In function 'priv_gst_parse_yyparse':
grammar.tab.c:1809:7: error: too few arguments to function 'priv_gst_parse_yylex'
   if (yychar == YYEMPTY)
       ^
./grammar.y:39:5: note: declared here
 int priv_gst_parse_yylex (void * yylval_param , yyscan_t yyscanner);
     ^

The patch to fix is pretty simple, didn't test it with older bison though.

Patch to fix build with bison 3.0

Thanks for the patch! Unfortunately this seems to break the build with bison 2.x:


  CC     libgstparse_la-grammar.tab.lo
grammar.tab.c: In function 'priv_gst_parse_yyparse':
grammar.tab.c:1992:7: error: too many arguments to function 'priv_gst_parse_yylex'
./grammar.y:39:5: note: declared here
make: *** [libgstparse_la-grammar.tab.lo] Error 1
Comment 3 Lubosz Sarnecki 2013-08-03 14:59:29 UTC 
The patch fixes the build, but it crashes

bmonkey@bbook:~$ gst-launch-1.0 videotestsrc ! autovideosink

Any chance you could provide a stack trace with full debugging symbols?

gst-launch freezes at this step with debugging symbols:

0:00:00.044489880 11820       0x717a00 INFO            GST_PIPELINE gstparse.c:322:gst_parse_launch_full: parsing pipeline description 'videotestsrc ! autovideosink '

i tried "-g -O0", "-g3", "-g" but it does not crash anymore.

Could you get a backtrace of that crash? Must be somewhere in the bison generated code
