hi: I am new to bro. After downloading the source  
code, I try to install it on my linux machine. First I  
run configure command. The output is as following:

[root@jqxin bro-pub-0.7a90]# configure

It seems fine. But when it comes to make. The output  
is as following:

[root@jqxin bro-pub-0.7a90]# make  
c++ -I. -O -Ilinux-include -c Func.cc  
Func.cc: In function `void do\_fmt (const char \*&, Val  
\*, ODesc \*)':  
Func.cc:247: `localtime' undeclared (first use this  
function)  
Func.cc:247: (Each undeclared identifier is reported  
only once for each  
function it appears in.)  
Func.cc:247: `strftime' undeclared (first use this  
function)  
make: \*\*\* [Func.o] Error 1

So I do not know how to tackle this problem. Would you  
please give me some hint? Thanks very much for your  
kind help.

yours,  
Xin

Same problem comes again... It's because of the library functions time.h is  
using. You can either change the line

#include \<sys/time.h\>

in Func.cc to

#include \<time.h\>

or add this line directly. Then everything is done.

Good luck,
