Re: ./snmpd:not found

The problem here was that I was trying to statically compile the snmpd. and obviously by looking at the size of snmpd it was dynamically linked.  The size of snmpd was 32K, while it should be around 1Meg!

So, the question is: why does it not statically compile despite the proper flags beeing set ? 

The answer is: DO NOT SPECIFY a "-v" flag (verbose output) in the CFLAGS!!!

If you do so, the config script will think static linking is not supported and a dynamic version will be created instead, without properly warning you! 
If you look carefully in the generated output file, you will see a line warning you of the fact, but it is lost in soooo many other things...

Anyways, many thanks for those of you who spent time trying to solve this issue with me.

Sylvain

Hmmm...
  So one command states that it's not using shared libraries,
while the other claims that it is?  That sounds strange to me.

I presume this is being built for some form of embedded system.
Have you tried asking for advice from that community?
They probably know more about the pitfalls of porting software
to that environment than we do.

I did run make install, and copied everything but the many .h files (I had to remove the .h file since the target is limited in disk spave).

Here is the script I am using to run the install command:

MAKELEVEL=3
GATEWAY_COMPILATION_PLATFORM= arm
MFLAGS=-w
MAKEFLAGS=w
LD_LIBRARY_PATH=$LD_LIBRARY_ PATH:/usr/local/lib
CFLAGS="-v -W -Wall -fPIC -mcpu=ep9312 -mfix-crunch-d1 -Wno-deprecated -DUSE_PTHREADS -MMD -DVOCAL_USE_DEPRECATED"
CPPFLAGS="-v -W -Wall -fPIC -mcpu=ep9312 -mfix-crunch-d1 -Wno-deprecated -DUSE_PTHREADS -MMD -DVOCAL_USE_DEPRECATED"
CONFIGURE_ARGS="--target=arm- linux --host=i686-linux"
export CONFIGURE_ARGS
export CPPFLAGS
export CFLAGS
export LD_LIBRARY_PATH
export MAKELEVEL
export GATEWAY_COMPILATION_PLATFORM
export MFLAGS
export MAKEFLAGS


./configure --host=arm-linux --target=arm-linux --with-cc=/usr/local/arm/ ep93xx-d1/bin/arm-linux-gcc --disable-applications --disable-manuals --disable-scripts --disable-snmpv1 --disable-privacy --disable-md5 --without-openssl --enable-mini-agent --with-out-mib-modules=" examples/ucdDemoPublic" --with-persistent-directory="/ var/net-snmp" --with-logfile="/var/log/ snmpd.log" --with-default-snmp-version=" 2" --with-install-prefix="/home/ sylvain/Download/net- snmp-5.5/ARG-temp-install" --with-ldflags=-Bstatic

Given the size of the object my guess would be that you did

./configure <options>
make

and then copied agent/.libs/snmpd to your device. Is that so? If that is
the case then you have only the driver for the agent, you need the shared
libraries as well since they contain the actual code of the agent.

I would suggest that you do 'make install' and copy the generated tree
to your device, then you could start removing things. I do not think you
should need anything but the libraries and the binary.

Hi,

I'm compiling net-snmp for an arm-linux embedded system.  However, when I try to run the snmp daemon on the embedded system, I get:

/usr/local/sbin # ./snmpd
-sh: ./snmpd: not found

But it is there!:
/usr/local/sbin # ls -la ./snmpd
-rwxr-xr-x     1 root    root   32859  Mar 10  14:40  2010  ./snmpd
 
 
Any idea what is going on?
 
Thanks!
