在使用net-snmp 5.7.3开发的子代理程序运行时遇到错误：'libnetsnmpmibs.so.30: cannot open shared object file: No such file or directory'。该问题通常由于LD_LIBRARY_PATH环境变量未正确设置导致。参照链接中的解决过程示例，通过设置环境变量或软连接可以解决此问题。

用net-snmp-5.7.3开发的子代理程序执行后，报错“./mysnmp: error while loading shared libraries: libnetsnmpmibs.so.30: cannot open shared object file: No such file or directory”

原因是 LD_LIBRARY_PATH环境变量没有定义，执行下面的语句：

export LD_LIBRARY_PATH = /usr/local/lib

解决过程示例：

root@map:/usr/local/lib# ldd /home/kpiss/net-snmp-5.7.3/agent/mibgroup/chanctsnmp 
        linux-vdso.so.1 =>  (0x00007fff577e2000)
        libnetsnmpmibs.so.30 => not found
        libnetsnmpagent.so.30 => not found
        libnetsnmp.so.30 => not found
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fc5207a7000)
        /lib64/ld-linux-x86-64.so.2 (0x00007fc520b70000)
root@map:/usr/local/lib#  export LD_LIBRARY_PATH=/usr/local/lib                 
root@map:/usr/local/lib# ldd /home/kpiss/net-snmp-5.7.3/agent/mibgroup/chanctsnmp 
        linux-vdso.so.1 =>  (0x00007fffef1fe000)
        libnetsnmpmibs.so.30 => /usr/local/lib/libnetsnmpmibs.so.30 (0x00007fc14b29c000)
        libnetsnmpagent.so.30 => /usr/local/lib/libnetsnmpagent.so.30 (0x00007fc14b03a000)
        libnetsnmp.so.30 => /usr/local/lib/libnetsnmp.so.30 (0x00007fc14ad50000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fc14a98a000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fc14a786000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fc14a568000)
        librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007fc14a360000)
        /lib64/ld-linux-x86-64.so.2 (0x00007fc14b70a000)
