opencv example application

Former Member

Hello,

I'm trying to run the example OpenCV application in the SDK on zedboard. But when I'm trying to run it , there is an error.

error: while loading shared libraries: libavformat.so.54: cannot open shared object file: No such file or directory

By following the below link

https://www.xilinx.com/support/documentation/sw_manuals/xilinx14_7/SDK_Doc/tasks/sdk_t_opencv_template.htm

I use the setenv  LD_LIBRARY_PATH = /usr/lib/opencv and try to run, error is

setenv: not found

Then I've copied the opencv libraries from the sdk's opencv to SD card from SSH terminal, mounted the sd card on to /mnt folder and given the below command in the Run configuration dialog box

export LD_LIBRARY_PATH = /mnt/opencv   then it says

export: : bad variable name

 

Does any one have an idea how to solve this ?

Regards

    Hi Kevin & Mario,

    [1] while using ldd, a message saying that "it is not a dynamic executable" so I tried using readelf and... all the shared libraries are present in the image created

    [2] While building petalinux again, this error is coming. "[ALL  ] /opt/pkg/petalinux-v2015.2.1-final/components/linux-kernel/xlnx-3.19/Makefile:925: recipe for target 'vmlinux' failed

    [ERROR] make[4]: *** [vmlinux] Error 1" I've searched and found to disable docsrc in kernel. But it is already disabled. Also i've tried to disable the advanced bootable images storage settings in auto hardware settings from petalinx-config. But no use. Can you please say me how to solve this ?
