Greetings !

I have added *opencv* into my yocto build using *"IMAGE_INSTALL:append = " opencv"* and could successfully able to build my target image.
But after building toolchain using *"bitbake meta-toolchain-qt5"* I not getting opencv related files in toolchian.

Please help me with the procedure to include *opencv into my toolchain*.

Thanks

You have to build image based sdk so whichever image you are building
generate the sdk for it by running

Bitbake -cpopulate_sdk your-image will do it and that will include whatever
you have in image install

Thanks Khem Raj for your replay.

I followed procedure suggested by you . I used *"bitbake -c populate_sdk core-image-minimal"* , now I can get the opencv related files in my toolchain.
But with this it seems few QT5 related files are missing so I could not able to cross-compile my Qt5 application which was working with toolchain created using "bitbake meta-toolchain-qt5".

*Error log:*

poornesh@IBE2113N:~/Desktop/qtapp/opencv/provu-v0.0.4.04$ qmake
Cannot find feature spec_pre.prf
Error processing project file: /home/poornesh/Desktop/qtapp/opencv/provu-v0.0.4.04/provu.pro
*---------------------------------------------------------------------------------------------------------------------------------------*

May I get your suggestions on this !

Thanks,

Add opencv to TOOLCHAIN_TARGET_TASK variable might help to get into non
image based sdk
