[Rpcap-users] Found the reason: Re: rtdump won't compile...

Matt,

The problem in compilation is only with the pcap_dump* functions.  I
was able to reproduce the problem in the morning, but then had to break
because of domestic concerns...:).  I sat again to look at the problem
again just now, and found the reason.

If you check your error output on the rtdump build, you will notice
that the errors all pertain to pcap_dump, pcap_dump_open,
pcap_dump_close, and related structures. 

Essentially, librpcap as installed in /usr/local/lib is not exporting
the pcap_dump functions at all.  I did not notice this problem when
building on my default system since I have libpcap installed in the 
default (/lib) directory, and the linker simply linked against the
pcap_dump functions in libpcap.so by default when it could not find
them in librpcap.  I found this when I ran nm on librpcap on both my
systems, and could not find these functions.  You can check this by
running nm on librpcap and  looking for pcap_dump, pcap_dump_open, etc.

I will now fix this and get back to you ASAP.

Thanks for your input and patience.

Cheers,  

Krishnan
