Hi ,

I am trying to execute some sample OpenCV examples on 8148 hardware .

I followed below link to build OpenCV for ARM Cortex-A8 -

http://processors.wiki.ti.com/index.php/Building_OpenCV_for_ARM_Cortex-A8 

But when I am trying to run ,am getting following errors like "Can not connect to X server "

I checked the x server log file .

PFB log file -

5187.xserver_logfile.txt 
module ABI major version (12) doesn't match the server's versi on (11):

    Hello,

    I am not familiar with OpenCV on DM8148 but you could check this thread:

    Hi Margarita,

    I got some old e2e links for openCV with 8148 .As per the link I have to install C6EZAccel package .

    But C6EZAccel is required for the DSP communication from ARM and running algo  on DSP core .

    I want to run my algo only on ARM core :cortex A8 only .So I think for this C6EZAccel is not required .

    I am able to run some QT demos on my hardware .

    But when I am trying to run the my (lane detection ) algorithm on ARM ,I am getting error like can not connect X server .

    But I am confused that I have changed the dependency from X server to QT to see the output of my algo but still QWS is taking X server path only (instead of QT).

    Can you help me by providing  steps to execute the ARM based OpenCV examples .

    I am having below ref and I have followed all the steps mentioned but still having above mentioned issue -

    Please do the needful .
