This is first time with python so I don't know how to fix this problem. Can someone help me?
Thank you

Hi タイ チャン,

This seems like to be linux environment issue for installation. As you are installing directly on the board, it should not give you issue for gcc not found. We will try to replicate it here. Till then can you let us know which is the yocto and linux kernel version you are using?

Also try installing build-essential and then run above command?

I installed build-essential by adding "IMAGE_INSTALL + = packagegroup-core-buildessential". Then "pip install spidev" successfully but "pip3 install spidev" still failed.

Could you give me advice to solve this problem?

Thank you so much

Hi タイ チャン,

Try installing glibc. And make sure that limit.h, stdio.h is in your filesystem and the path is included in the environment variable.

Hi  karan gajjar
I will try installing build-essential.
I using fsl-yocto-L4.1.15_2.0.0-ga, kernel version 4.1.15.

Thank you so much
