[Snort-users] Tip: Building Snort 2.2.0 under 64-bit Sun sparc sol9

This is a heads-up/FYI for building snort on 64-bit sparc solaris 9.
I had to spend a day at it - unexpectedly (but this is not a complaint.)
There were 3 hurdles to overcome. Google helped --A LOT (of course!)

Cheers!
I hope this helps someone.
Thanks to all posters and contributors to this site. I am learning
a whole lot from you.



Limitations:
1) these may not the most elegant or complete methods.
   I needed it to work this weekend!
2) there may be more problems not yet encountered - only the problems 
listed
   were resolved.
3) this is for a Sun/Solaris 9 64 bit system. Had I been running 32 bit 
   mode, i might have encountered different or no problems.

My system:
SunOS 5.9 sun4u sparc SUNW,Ultra-2
Memory size: 512 Megabytes
2 sparcv9 processors / 168 MHz

gcc version 3.4.2

--- problems and resolution ---

1-  libpcap
./configure error generated:

checking for pcap_datalink in -lpcap... no

   ERROR!  Libpcap library/headers not found, go get it from
   http://www.tcpdump.org
   or use the --with-libpcap-* options, if you have it installed
   in unusual place
-bash-3.00$

hint: in configure.log
configure:5826: checking for pcap_datalink in -lpcap
configure:5859: gcc -o conftest -g -O2 -Wall   -DBSD_COMP

ld: warning: file /usr/local/lib//libpcap.a(pcap.o): wrong ELF class:

pcap_datalink                       /var/tmp//ccM9VScB.o
ld: fatal: Symbol referencing errors. No output written to conftest

problem:
     linker not set for 64-bit mode
Fix: force gcc to 64-bit mode
     sudo env CC="gcc -m64" sh ./configure --with-mysql=/usr/local/mysql
result: worked for me.

I figured this one out, with help from George. Posting it so that I can
find it again once I run into this issue a year from now.

The only place in the code where I saw IXDR_GET_LONG being referenced
was in detection-plugins/sp_rpc_check.c
As far as the includes, this symbol was only defined in rpc/xdr.h
(which George pointed out), but this file wasn't included in the snort 
source.
After trying (unsuccessfully) to "#include <rpc/xdr.h>" at the top of
sp_rpc_check.c, I just took the part where this symbol is defined in

xdr.h
and threw it into sp_rpc_check.c: "#define IXDR_GET_LONG(buf)
((long)ntohl((ulong_t)*(buf)++))". After that, no issues...
