How to cross compile NET-SNMP

[Hector Oron <hector.oron@gmail.com>]

Hello folks,


 I've been trying to cross-compile net-snmp for ppc over i386. I have
build a script with some of the options that we should select. I'm able
to generate my binary file, but when i start snmpd agent it doesn't
work as I expect.


Target: MPC-855 (ppc), glibc-1.99, kernel-2.4.18

Host: i686 (pentium4), glibc-2.3.2, kernel-2.6.8 and kernel-2.4.27 (i have tried both)

Toolchain: 1) Crosstool - gcc-3.4.0 - glibc-2.3.2
                
2) Emdebian toolchain - gcc-3.3 - glibc-2.3.2


I have build a script with several switches for cross compilation, "mytool" (see attachment)

I have been able to generate a binary file by several ways, but i got stuck starting snmpd agent:

$ file usr/sbin/snmpd 
usr/sbin/snmpd: ELF 32-bit MSB executable, PowerPC or cisco 4500,
version 1 (SYSV), for GNU/Linux 2.2.0, statically linked, not stripped


$ cat /etc/snmp/snmpd.conf

rocommunity open_public


When I start daemon as: 
/ # snmpd -DALL -Le -f -C -c /etc/snmp/snmpd.conf

[...]

wtest: oid cmp: .2  --- off = 1, in off = 1 test = 1

trace: netsnmp_ds_set_string(): default_store.c, 283:

netsnmp_ds_set_string: Setting LIB:6 = "snmpd"

trace: snmpd_register_config_handler(): agent_read_config.c, 281:

snmpd_register_app_config_handler: registering .conf token for "injectHandler"

trace: netsnmp_register_callback(): callback.c, 159:

callback: registered (0,0) at 0x101997a8 with priority 0

trace: netsnmp_callback_transport(): snmpCallbackDomain.c, 416:

transport_callback: initialized master listening on 1

%----  here it doesn't show any more output


On my host (working fine), it continues as follows:

trace: which_module(): parse.c, 3590:

parse-mibs: Module SNMPv2-SMI not found

trace: which_module(): parse.c, 3590:

parse-mibs: Module RFC1155-SMI not found

trace: which_module(): parse.c, 3590:

parse-mibs: Module RFC1213-MIB not found

trace: netsnmp_tdomain_init(): snmp_transport.c, 191:

tdomain: netsnmp_tdomain_init() called

trace: netsnmp_tdomain_dump(): snmp_transport.c, 236:

tdomain: domain_list -> { iso.3.6.1.6.1.1, "udp" } -> {
iso.3.6.1.3.91.1.1, "tcp" } -> { iso.3.6.1.4.1.8072.3.3.2, "unix" }
-> { iso.3.6.1.4.1.8072.3.3.4, "udp6/ipv6/udpv6/udpipv6" } -> {
iso.3.6.1.4.1.8072.3.3.5, "tcp6/tcpv6/tcpipv6" } -> [NIL]

[...]

That happens when compiling statically, but when i compile dinamically
it is missing some libraries, some of them included in glibc (libm,
libwrap0, libz, ...)

I have try all the posible configurations on "mytool" and some more,
with same results, some help would be appreciated, also i'd give some
cash in case of submitting a working binary (or working solution) for
my target board.
 

You have a explanation of the problem here:
http://linuxupc.upc.es/~hecormar/netsnmp/ with config.log files and
debug messages when starting snmpd agent.

Please, ask for extra information if you need it.

Best Regards,
