Hi everyone

I'm trying to install libpcap 1.0 for snort, but when I put the make command apears the following:

[root@fatima libpcap-1.0.0]# make
gcc -O2 -fPIC -I. -DHAVE_CONFIG_H -D_U_="__attribute__((unused))" -c ./fad-getad.c
In file included from ./fad-getad.c:67:
/usr/include/linux/if_packet.h:52: error: expected specifier-qualifier-list before __u32
make: *** [fad-getad.o] Error 1
[root@fatima libpcap-1.0.0]#

I'm running centOS 5, I've run de ./configure and doesn't mark an error what can I do?
