Hi,

Thanks for reply.

It reports that I really have libcrypto.a. Why it still asks for libcrypto.=
so.0.9.7 when I use --disable-shared in my configure phase?=20
In your description, it should link static libraries(libcrypto.a) when I co=
nfigure with --disable-shared.
Or I need to do other thing to indicate libcrypto.a is available?

Thanks,

iTAS Tewen=20

Which versions of the crypto library do you have installed?
What does "locate libcrypto" report?

If it doesn't mention 'libcrypto.a', then you may need to install
the openssl-devel RPM (or similar).

> Parameter "--disable-shared" seems unuseful!

The linker can only link in the static libraries that it can find.
If you don't have a static version of the crypto library available,
then it will have to use the dynamic version.

Hi,

Thanks for reply.

I have tried --disable-shared in my configure phase.

./configure --disable-shared --target=3Dmips-linux --with-cc=
=3Dmips2_fp_be-gcc --host=3Dmips --with-endianness=3Dbig --prefix=3D/not/us=
r/ --with-install-prefix=3D/tmp

But it still shows "./snmpd: error while loading shared libraries: libcrypt=
o.so.0.9.7: cannot open shared object file: No such file or directory".

Parameter "--disable-shared" seems unuseful! Or I make a mistake in my step=
s?

I think I have already seen the same problem, (I am also cross-compiling 5.=
1.1) end let me say that it is an hard Work and if your MIB has some (read-=
create) tables, you will not be able to implement.=20

I think if you the flag =A1Vdisable-shared when configuring, it will solve =
your problem.

Subject: net-snmp cross compile

=20

Hi,

=20

I tried to cross compile net-snmp-5.1.1, but I failed.

My steps were as following:

=20

step 1: ./configure --target=3Dmips-linux --with-cc=3Dmips2_fp_be-gcc --hos=
t=3Dmips --with-endianness=3Dbig --prefix=3D/not/usr/ --with-install-prefix=
=3D/tmp

step 2: make
step 3: make install
step 4: cd /tmp
step 5: tar cvf net-snmp-target.tar not

step 6: Then copy the tar file to my target, and on my target
step 7: cd /
step 8: tar xvf net-snmp-target.tar

=20

Then I tried to run snmpd on my target, but I got an error message: could n=
ot find libcrypto.so.0.9.7 bala bala ...

=20

=20

=20

Question 1: How can I cross compile net-snmp as static link ? I mean I can =
run snmpd without moving libcrypto.so.0.9.7 to my target(/usr/lib). Is ther=
e any parameter can be set in ./configure phase to resolve this problem?

=20

Question 2: Although my snmpd can be executed. It seems no response from sn=
mpd when I send a snmp request to it (I used "netstat -a" to check it, port=
161 is opened, but its state is not listening.). I am sure my snmpd.conf f=
ile is correct. So is there any thing wrong in my cross compile procedure? =
Or I missed something important when cross compiling?

=20
