Thanks Michael Mirold for the answer of my last question.
When I want to use more .bro files, such as:
./bro -i eth0 ftp.bro http.bro,
then the program tell me that it can't go on when it analy the http.bro.
but when I use one .bro file , ftp.bro or http.bro ,they are all ok.
I follow these steps to compile the bro.
./bro -i eth0 //note: eth0 is my netcard
but there is nothing appear in the screen. So I debug the program ,
I found it loop in the function yyparse( ) in main.cc line 220, no
longer go out from the yyparse();
what caused these?
