NET-SNMP 5.7.3 Sub-agent libnetsnmp.so.30 not found solution

After executing the sub-agent developed with net-snmp-5.7.3, the error "./mysnmp:error while loading shared libraries:libnetsnmpmibs.so.30:cannot open shared Object File:no such file or directory "

The reason is that the LD_LIBRARY_PATH environment variable is not defined and executes the following statement:

<strong><span style= "Font-size:24px;color: #ff0000;" >export ld_library_path=/usr/local/lib</span></strong>
