net-snmp问题？

Question

Libraries have been installed in:
/usr/local/snmp/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:

• add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
  during execution
• add LIBDIR to the 'LD_RUN_PATH' environment variable
  during linking
• use the '-Wl,-rpath -Wl,LIBDIR' linker flag
• have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

sudo vi /etc/profile
在此文件中加入此配置项
export LD_LIBRARY_PATH=/usr/local/snmp/lib
