libpcap.so.1 => not found

[shah hemal]

Hi,

I am trying to run tool on linux. It caught into the error :
"/cbm: error while loading shared libraries: libpcap.so.1: cannot open shared object file: No such file or directory "

From the forums i found that out put of
[root@hemal cbm-tool]# ldd cbm
linux-gate.so.1 => (0x00110000)
libnsl.so.1 => /lib/libnsl.so.1 (0x0067c000)
libpcap.so.1 => not found
libdl.so.2 => /lib/libdl.so.2 (0x008ff000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00c8f000)
libm.so.6 => /lib/libm.so.6 (0x008d4000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00c76000)
libc.so.6 => /lib/libc.so.6 (0x0077e000)
/lib/ld-linux.so.2 (0x0075f000)

I tried to look into :

[root@hemal ~]# ls /usr/lib | grep libpcap
libpcap.so.0.9
libpcap.so.0.9.7

Further i downloaded libpcap-1.1.1.tar.gz and installed(configure, make, make install) under root folder.

Still it is not able to find libpcap.so.1

Kindly help to get out of this issue. Many thanks in Advance.

Thanks,

Hemal Shah

Hi Hemal,

First checkout "rpm -qa  | grep -i libpcap", and check for libpcap and libpcap-devel rpm is installed or not.

And you have installed using .tar.gz then library is installed in /usr/local/lib directory, then set

/usr/local/lib
/usr/lib

into /etc/ld.so.conf and then execute ldconfig command.

Or one thing is that whatever tool you executed it needs that particular library only, then solution is link using "ln" command to your libpcap.so.1 library.

Have you installed libpcap using RPM or YUM ? If no, then try to do that.

Can you tell us what kind of tool you are trying to run ?

I think libpcap-devel will solve your problem

yum -y install libpcap*

I think If you are installing your tool using source then you need a libpcap-devel also.

Still it is not able to find   libpcap.so.1


Kindly help to get out of this issue.  Many thanks in Advance.

cd /usr/lib
ln -s /usr/lib/libpcap.so.0.9 libpcap.so.1

Then try again.

Please letus know it is working or not.
