ERROR ld so object LD PRELOAD cannot be preloaded ignored

Question

I am using ubuntu 12 04  Every time I start my bash terminal and every time when I finish typing a command and press enter    I get this message       ERROR  ld so  object   usr lib liblunar-calendar-preload so  from   LD PRELOAD cannot be preloaded  ignored    It is weird  So what is the environment variable LD PRELOAD used for  And what is the going on behind the scene   Thanks

The linker takes some environment variables into account. one is LD_PRELOAD

from man 8 ld-linux:

LD_PRELOAD
          A whitespace-separated list of additional,  user-specified,  ELF
          shared  libraries  to  be loaded before all others.  This can be
          used  to  selectively  override  functions   in   other   shared
          libraries.   For  setuid/setgid  ELF binaries, only libraries in
          the standard search directories that are  also  setgid  will  be
          loaded.

Therefore the linker will try to load libraries listed in the LD_PRELOAD variable before others are loaded.

What could be the case that inside the variable is listed a library that can't be pre-loaded. look inside your .bashrc or .bash_profile environment where the LD_PRELOAD is set and remove that library from the variable.

It means the path you input caused an error  In your LD PRELOAD command  modify the path like the error tips    usr lib liblunar-calendar-preload so

Thanks for the responses  I think I ve solved the problem just now   Since LD PRELOAD is for setting some library proloaded  I check the library that ld preloads with LD PRELOAD  one of which is  liblunar-calendar-preload so   that is not existing in the path   usr lib liblunar-calendar-preload so   but I find a similar library  liblunar-calendar-preload-2 0 so   which is a difference version of the former one    Then I guess maybe liblunar-calendar-preload so was updated to a 2 0 version when the system updated  leaving LD PRELOAD remain to be   usr lib liblunar-calendar-preload so   Thus the preload library name was not updated to the newest version    To avoid changing environment variable  I create a symbolic link under the path   usr lib   sudo ln -s liblunar-calendar-preload-2 0 so liblunar-calendar-preload so   Then I restart bash  the error is gone

You can check  etc ld so preload file content  I fix it by      echo       etc ld so preload

If you want to make sure that the library is loaded if and only if the program lunar-calendar-gtk is launched  you can apply this   You set the environment variable per command by prefixing the command with it     LD PRELOAD  liblunar-calendar-preload so  printenv  LD PRELOAD  liblunar-calendar-preload so   printenv  LD PRELOAD      You can then choose to put this in a shell script and make lunar-calendar-gtk a symlink to this shell script  replaceing the original referencee  This effectively makes sure that the library is loaded everytime the original application is executed   You will have to rename the original lunar-calendar-gtk to something else  which might not be too intriguing as it possibly may cause issues with uninstallation and upgrading  However  I found it useful with a former version of Skype
