How to add libraries to the runtime/embeddem_arm_sdk cross-compilation environment

[STATEABC]

Hello,

I'm running the object_detection_demo in my SoC to process an image, but I get the following error:
[ ERROR ] 0opencv(4.8.0)/home/coredla_work/runtime/hps packages/opencv/modules/highgui/src/window.cpp:1272: error: (-2: Unspecified error) The function is not implemented, Rebuild the library with Windows, GTk+ 2.x, or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure the script in function 'cvshowImage'

So I ran the sudo apt install libgtk2.0-dev command on Ubuntu and set the CMAKE_FLAGS="${CMAKE_FLAGS}" in build_hpspackages.sh. -DWITH_GTK:BOOL=ON"
CMAKE_FLAGS="${CMAKE_FLAGS} -DWITH_GTK_2_X:BOOL=ON" and re-ran ./create_hps_image.sh, but the generated executable still reports the above error.

In runtime/embedded_arm_sdk, I found that after running source environment-setup-linux, the GTK version number cannot be returned using pkg-config --modversion gtk+-2.0. Therefore, I would like to know how to install the libgtk2.0 library when cross-compiling for embedded_arm_sdk.

Hi STATEABC,

How you install or build OpenCV?

Below is the common solution for the encountered OpenCV error:

Try this command to install target-specific GTK2 Development libraries:

sudo apt-get install libgtk2.0-dev:armhf

Hello,
Thanks so much for your solution, but it doesn't work for me.

I installed OpenCV according to the instructions at https://www.intel.com/content/www/us/en/docs/programmable/768970/2024-3/installing-toolkit.html

I tried installing it using sudo apt-get install libgtk2.0-dev:armhf, but I get the following error:

Reading package lists... Done

E: Unable to locate package libgtk2.0-dev:armhf
E: Couldn't find any package by glob 'libgtk2.0-dev'
