I have this program that makes use of the ffmpeg libraries. I was able to compile it and successfully include the necessary header files, problem is, when i start running the program using the command

>g++ sample.cpp -lavcodec -lavformat

i get the following message:

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

my program compiles in g++ and is on the ubuntu linux distribution environment. i installed the libraries using the following command:

> ./configure --disable-vhook --disable-ffserver --enable-shared
> make
> make install

and no errors were generated. where could the error be from? is there a need to set any path variables for my program to be able to see the shared libraries?
i checked the usr/local/lib folde and verified that the libraries are really there.. how can i solve this problem? please help..

Use synaptic (or apt-get at the command line) to install all the needed libraries.

thanks, i'l give it a try

i found out what the problem was. it was with the linux distribution i have. the libraries were installed in the folder usr/local/lib but my OS only looks at the folder usr/lib for the shared libraries. to solve the problem, i created links to the libraries and placed these links in usr/lib. my program then work as it shud. still, thanks to those who responded.
