Re: Help! regarding libpcap.

Hi Burce,
At first, I'm sorry replay late. I've test build libpcap without ports
and using same tar ball. The error message still output.
SLT2# make
gcc -O2 -I. -DHAVE_CONFIG_H -D_U_="__attribute__((unused))" -c
./pcap-null.c
./pcap-null.c:43: error: conflicting types for 'pcap_activate'
./pcap/pcap.h:266: note: previous declaration of 'pcap_activate' was here
*** Error code 1
Stop in /usr/ports/distfiles/libpcap-1.0.0.
SLT2#
Thank you!
-Leo

Hi,
I can't think what might be causing this for you... Do you have other
pcap libraries installed on the system? Perhaps a define is incorrect.
Are you trying this on a 7.2 or a HEAD system? I believe 7.2, so that
should rule out changes in HEAD.
Do you have BPF headers present on the system? Have you checked the
output of config.log? Do you have a bpf device in your kernel?
-- I think that might be it. The fix might be to specify
--with-pcap=bpf in CONFIGURE_ARGS in the port.
I just built the port on an i386 system tracking RELENG_7 sources, and
couldn't reproduce this problem, although I have bpf in kernel there.
thanks,
BMS

Hi Bruce,
I don't have other pcap lib installed on this box. Previously installed
a libpcap 0.9 on this box , But I've deleted this version. On my box,
not enable BPF. Let me try if enable the feature.

That's probably what it is. Can you try the following:
* give pcap configure --with-pcap=bpf WITHOUT having bpf in your kernel
config.
* try enabling bpf in kernel config and building the port as usual.
Most likely libpcap's new configure script is detecting the lack of
/dev/bpf* and assuming there is no packet capture support in the system.
This needs to be fixed for cross compiling to be possible. If you could
try at least the first fix then this is the answer.
thanks,
BMS

Hi Bruce,
I've tried 2 method on my box. that you previously mentioned. Both of
