libwireshark.so.2: cannot open shared object file: No such file or directory

I am using ubuntu and learning computer networking using wireshark, but my wireshark seems to be to slow and always out of response, so I decide to download the source code, and recompile it.

Before today, my wireshark is installed through

Code:

apt-get install wireshark

.

So, I delete it by

Code:

apt-get remove wireshark

, and trying to delete all the files related to wireshark in my system, so I do this:

Code:

locate wireshark | grep -viE 'unimous' | xargs sudo rm -rf

.

And then, download wireshark's source code, ./configure, make, sudo make install.

When all the thing is done, I am trying to open wireshark using the command

Code:

sudo wireshark

, but this error happens:

Code:

wireshark: error while loading shared libraries: libwireshark.so.2: cannot open shared object file: No such file or directory

What is libwireshark.so.2?
What is libwireshark.so.2 's job?
I have compiled the all wireshark, but why there is still something that is missed?

How did you determine that was caused by that version of Wireshark?

Code:

# Locate the wireshark binary:

sudo which wireshark

# or if your databases are up to date:

sudo locate wireshark

# Now check where it expects the libraries:

ldd /path/to/where/you/located/wireshark

# * If you still have the directory you compiled the source code in then enter that directory and run:

make -n install 2>&1 | grep libwireshark.so

# to see where 'make install' would install it to.

# The configure --prefix default should be /usr/local so libs end up in /usr/local/lib.

# Now update ldconfig:

sudo ldconfig

# and see if it picks up the location:

sudo ldconfig -p|grep libwireshark

# 

# If it does not then edit and update:

echo /usr/local/lib >> /etc/ld.so.conf.d/usrlocal.conf

sudo ldconfig

sudo ldconfig -p|grep libwireshark
