Hi Tilak,

try "ldd" against your plugin to see if any library is not found.

Example:

# ldd /usr/lib/nagios/plugins/check_mysql
        linux-vdso.so.1 (0x00007fff277ff000)
        libmysqlclient.so.18 => /usr/lib64/libmysqlclient.so.18
(0x00007f4895f84000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f4895d68000)
        libc.so.6 => /lib64/libc.so.6 (0x00007f48959ba000)
        libz.so.1 => /lib64/libz.so.1 (0x00007f48957a4000)
        libssl.so.1.0.0 => /lib64/libssl.so.1.0.0 (0x00007f489553a000)
        libcrypto.so.1.0.0 => /lib64/libcrypto.so.1.0.0 (0x00007f4895167000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00007f4894f63000)
        libm.so.6 => /lib64/libm.so.6 (0x00007f4894c65000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f4896489000)

So, my MySQL plugin found all requested libraries. Does your output look
similar?

HTH, Werner
