  <a href="http://scaryreasoner.wordpress.com/2007/11/17/using-ld_preload-libraries-and-glibc-backtrace-function-for-debugging/" rel="nofollow noreferrer">http://scaryreasoner.wordpress.com/2007/11/17/using-ld_preload-libraries-and-glibc-backtrace-function-for-debugging/</a></p>
  
  <p>but getting error: "ERROR: ld.so: object 'libwrap_ioctl.so' from LD_PRELOAD cannot be preloaded: ignored."</p>
  
  <p>what can cause it? 
  system - Archlinux, kernel 2.6.32 </p>
  
  <p>thank you for answers</p>
  
  <p>upd1:
  "Check with ldd libwrap_ioctl.so if some dependency of this library is missing."</p>
  
  <p>checked. no, i have all needed libraries </p>
