Your OpenCV and your libcv aren't installed in the same path. If you compile libcv from source, using ./configure --prefix=SAME_PATH_AS_OPENCV will fix this.

i did this,

1> tar xvzf OpenCV-1.0.0.tar.gz
cd opencv-1.0.0

2>./configure --prefix=/opencv_library_install_path/opencv-1.0.0
make;
3>make install
4>Libraries have been installed in:
/opencv_library_install_path/opencv-1.0.0/lib
5>ln -s opencv-1.0.0 opencv
5>cd /.../opencv-1.0.0/
make check
i donn know where i m getting wrong????
after this i have compiled my program like below,
1>cd /where/you/have/the/source/code
PKG_CONFIG_PATH=/where/you/have/installed/opencv/lib/pkgconfig:${PKG_CONFIG_PATH}
export PKG_CONFIG_PATH
2>pkg-config --cflags opencv
pkg-config --libs opencv
3>gcc `pkg-config --cflags opencv` `pkg-config --libs opencv` -o my-opencv-prgm my-opencv-prgm.c

even then i m getting same error so wat to do ,can you give me the procedure for running sample code in c or tell me where i m getting wrong.

Did you install libcv separately, or is it a part of this? You need to install both of them to the same path.

I have no personal experience with OpenCV. But, you should compile/install OpenCV with the command ./configure --prefix=/usr Or wait until John A comes in here and destroys my tiny amount of knowledge in Linux with his far superior amount.

thnxx in advance.

I found same problem.

you must add your opencv path to folder /etc/ld.so.conf.d/ by create some file relate to opencv. for example

opencv_path.conf
(details in this file are)
/usr/local/lib
/usr/local/include
(both of above are default path of opencv installation)

then save file and mv or copy opencv_path.conf file to /etc/ld.so.conf.d and run "ldconfig" command again.

goodluck
