Difficulties with building OpenCV libraries in yocto

[janšrámek]

Hi all,

I have difficulties with building toolchain including opencv libraries and includes. I'm using branch Fido, however a tried also Daisy and Dora. I get same results. When I build via "bitbake meta-toolchain-qt" I get no errors. After installation opencv and opencv2 folder is missing in <sysroot>/usr/include/ folder. I Looked around for few hour and built toolchain more that 20 times and still getting these output.

Does anybody know why is this happening?

This is output from installation of toolchain:

Hello Jan Šrámek,

Are you still having this issue? Have you tried the BSP Release? You should be able to bake these libraries on the latest release (3.14.28) but I’m not sure they will work on the Community BSP.

I would also make sure that the ACCEPT_FSL_EULA variable is set to 1, since these libraries may require it.

Hi gusarambula,

Thank you for reply and forgive me that i didn't respond for long time.

So, I tried to change EULA parameter and nothing changed. it is still missing. Regarding question if I'm using BSP release. Well, I am not sure. I just follow instruction and I do not know structure of these releases.

Do you have some idea?

Thank you in advance

Jan.
