AM572x linux kernel compiling error

canfoderiskii

Processor-SDK: 3.01.00.06

OS: Ubuntu 16.04.1

I tried to compile the kernel and before compiling I sourced the /opt/ti-processor-sdk-linux-am57xx-evm-03.01.00.06/linux-devkit/environment-setup file, which will add the cross compiler executable into PATH. But, I got an error which says gnu/stubs-soft.h can not be found. This error is strange, because compiler should've used hard float EABI and I did have the gnu/stub-hard.h file.

I found that if i only add the '/opt/ti-processor-sdk-linux-am57xx-evm-03.01.00.06/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/' into PATH, without sourcing the environment-setup, kernel can be compiled correctly.

How could this happen? Which part of ''environment-setup' affects the compiling?

Hello canfoderiskii,

Please, check this post.

You can start to separately comment out every line in the environment-setup, in order to narrow down and find which line leads to this behaviour, it can be caused by some configure flags or the environment-setup may changes some paths.

Best regards,
Kemal

thanks for the information.

I've checked the content of environment-setup file, the CPATH and PKG_CONFIG_PATH variables affected the kernel compiling.
