Snort compilation errors - error while loading shared libraries: libdnet.1: and libsfbpf.so.0 error

While compiling snort source, you will often encounter the following errors:

 error while loading shared libraries: libdnet.1:

Do this to get rid of the error:


#cp /usr/local/lib/libdnet.1.0.1 /usr/local/lib/libdnet.so.1.0.1
#/sbin/ldconfig

If this does not help, try this:
#ln -sf /usr/local/lib/libdnet.1.0.1 /usr/lib/libdnet.1
#/sbin/ldconfig

If that still does not help,
#LD_LIBRARY_PATH=/usr/local/lib
#export LD_LIBRARY_PATH

Another error that is encountered is:

error while loading shared libraries:
libsfbpf.so.0: cannot open shared object file: No such file or directory

To get rid of this error, do:
#/sbin/ldconfig

If this does not help, add '/usr/local/lib' to '/etc/ld.so.conf'

Finally, test the snort instance:
#snort -c /etc/snort.conf -T

These solutions have been tested on CentOS/SL variants and they work well.
