yocto zeus branch toolchains compile optee_example code ,ModuleNotFoundError: No module named 'Crypto'

gonewtinwind

Hi all,

yocto zeus branch toolchains compile optee_example code ,ModuleNotFoundError: No module named 'Crypto'

(maaxbaord sumo branch worked well).

 

I use yocto toolchains to cross compile optee_example code,

error happened:

from Crypto.Signature import PKCS1_v1_5

ModuleNotFoundError: No module named 'Crypto'

but I find in toolchain folder, the Crypto folder is there:

./sysroots/aarch64-poky-linux/usr/lib/python3.7/site-packages/Crypto

It seems the compiler can not find it ?

I have added :

IMAGE_INSTALL_append +=" python3-pycryptodome " in local.conf

any help?

About 2 year ago,I posted a similar question #3441 but that was in yocto bitbake process in early, could not generate the yocto image.
Today I play another board, I can build the image and the toolchain, the new issue is the toolchain compiler can not find the 'Crypto'

Thank you.

  • finally, I have found the solutions. I did  it 2 years ago for imx7 board. I remember again.

    do not need to modify the recipe.

    the toolchain does not include the Crypto package

    just manually copy Crypto to toolchain(I do not know how to modify somewhere in the compilation process to copy directly to make it, if someone knows how to do .please tell me ,thank you)
