在linux下编译gstreamer出现一下错误：

grammar.tab.c: In function 'priv_gst_parse_yyparse':

grammar.tab.c:1819:7: 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);
     ^

这是由于本机装的bison3.0中grammar的参数做了调整，具体是：

这样的话你可以像上面那样去修gst/parse/grammar.y，也可以把本机的bison3 从新装到2.5的版本
