[news.eclipse.tools.cdt] error while loading shared libraries

[franklyn@xxxxxxx (franklyn)]

hi all,

i just started with programming c++ under eclipse and everything works 
fine while compiling and linking. all libraries and headers are found. 
when i try to run the program from eclipse with the "Run" button it says 
"error while loading shared libraries: libcxcore.so.1: cannot open shared 
object file: No such file or directory". this is the same error when i am 
starting the program from console and the environment variable 
$LD_LIBRARY_PATH is not set correctly to include the directories where 
these shared objects are. 

1. i tried to set the variable in eclipse under Run->Environment it says 
"<terminated>..."and does nothing

2. and i tried to set the variable under Window -> Preferences -> C/C++ -> 
Managed Build -> User Variables. it says "rror while loading shared 
libraries: libcxcore.so.1: cannot open shared object file: No such file or 
directory".

it seems that the runtime libraries are not found.

did anyone face the same problem?
