setting LD_LIBRARY_PATH

[Sayantan Datta]

i need to use this line in Qt .pro file
LIBS += -lcv -lhighgui


now, for that i did need to set the LD_LIBRARY_PATH global variable.
So, i added this line,

$LD_LIBRARY_PATH:/usr/local/libs; export LD_LIBRARY_PATH

to the files, .bashrc in /home/sayantan/ and also in /etc/ld.so.conf
now, after this, when i run this command,
ldconfig -v

i get the error as
ldconfig: Can't stat $LD_LIBRARY_PATH:/usr/local/lib/; export
LD_LIBRARY_PATH: No such file or directory
ldconfig: Path `/usr/lib' given more than once
ldconfig: Path `/usr/lib64' given more than once


how do i fix it? Anyone, please help

I think it should be
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

a similar error persists, :(

[root@kenzo450D Desktop]# ldconfig -v > allthefiles.txt
ldconfig: $LD_LIBRARY_PATH:/usr/local/lib is not a known library type
ldconfig: Can't stat export LD_LIBRARY_PATH: No such file or directory

ldconfig: Path `/usr/lib' given more than once
ldconfig: Path `/usr/lib64' given more than once

I don't think you cannot put that in your .pro file. You need to set
the environment variable from the terminal.
