Hi Michael Steiger,
* Thanks for your valuable feedback.*
*
*
As per your suggestion, i have gone through the links as you suggested in
the previous mail.
I have searched config.log file in all possible configuration paths but i
can't able to find it .
*Please suggest me on following things*
*
*
1) What is the actual difference between configure options such as --host
and --build ?
2) Configure options such as --host, --build and --target are used for
cross compiling. Whether we need to specify processor/controller type for
each of these options? What is the format of specifying --host, --build
and --target ?
3) When i run uname -a on the UBUNTU host and target device i got
following output
**************UBUNTU***************
prashant@prashant-PC:~/Desktop/SNMP/SNMPDownloads/net-snmp/net-snmp-5.6.1.1$
*uname -a*
*Linux prashant-PC 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC

uname --help
Usage: uname [OPTION]...
Print certain system information. With no OPTION, same as -s.
-a, --all print all information, in the following order,
except omit -p and -i if unknown:
-s, --kernel-name print the kernel name
-n, --nodename print the network node hostname
-r, --kernel-release print the kernel release
-v, --kernel-version print the kernel version
-m, --machine print the machine hardware name
-p, --processor print the processor type or "unknown"
-i, --hardware-platform print the hardware platform or "unknown"
-o, --operating-system print the operating system
--help display this help and exit
--version output version information and exit
******************************************************************************
************* Target device*************
#* uname -a*
*Linux iSense 2.6.27 #227 Fri Apr 15 14:50:22 IST 2011 armv5tejl unknown*
# uname -h
BusyBox v1.12.0 (2010-09-24 12:04:01 IST) multi-call binary
Usage: uname [-amnrspv]
Print system information.
Options:
-a Print all
-m The machine (hardware) type
-n Hostname
-r OS release
-s OS name (default)
-p Processor type
-v OS version
******************************************************************************************
Now tell me based on this how can i set configure options such as --host,
--build and --target ?
*Thanks in Advance*

At least
host, target and build
> 2) Can you tell me the location(path) for config.log file ?
Should be in the same directory where configure is located
At least on my system.
Did you really look for it?
Maybe
http://www.pavius.net/2011/02/compiling-net-snmp-for-embedded-linux-using-the-eldk/
can help you.
But please use google (or another search engine) yourself.
Using "cross-compile net-snmp" you would have found
http://www.net-snmp.org/wiki/index.php/FAQ:Compiling_06
which partly explains the process.
