exection of opencv sample programs in c on fedora

[bswapnil]

hi all,
i m currently working in fedora n opencv.i m able to compile sample codes which are in c and generate executable from them i m reffering http://opencvlibrary.sourceforge.net/CompileOpenCVUsingLinux i did all steps correctly with no errors still i m getting "error while loading shared libraries: libcv.so.1: cannot open shared object file: No such file or directory" i have tried many options like exporting libraries setting paths ,i don't know where i m doing wrong pls help me out there it's urgent reply fast.....

thnxx in advance....

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.

hay thnxx....i did samething but it's giving me same error.....

error while loading shared libraries: libcv.so.1: cannot open shared object file: No such file or directory

how to ressolve this????

pls reply fast....

[linux]

Well, where did you install libcv and where did you install OpenCV?

[bswapnil]

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.

what is libcv and where should it located? can u tell me whole procedure from start to end how to execute sample programs in c in opencv????

pls it's urgent help me out, here i m stuck

thnxx in advance

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.

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

Why don't you install it through your package manager?
