minigui libminigui-1.6.so.十: cannot open shared object file: No such file or dir

minigui libminigui-1.6.so.10: cannot open shared object file: No such file or directory

安装完minigui和qvfb后，运行自带例程，出现下列问题： 

./listbox
./listbox: error while loading shared libraries: libminigui-1.6.so.10: cannot open shared object file: No such file or directory
 

原因：libminigui-1.6.so.10安装在默认路径/usr/local/lib下，

            ubuntu默认搜索库的路径不包括

             需要手动加上

解决：

             在/etc/ld.so.conf最好加上

                /usr/local/lib

                保存退出后，执行

               ldconfig

               OK
