Hello @debugging​ ,

Be sure to have made the source of the SDK environment script before trying to build:

https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Install_the_SDK#

PC $> cd $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v3.1.0/Developer-Package 
PC $> source SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

And before building you have to prepare the linux sources as specified in the getting started, in the part 1.1.1.2.3.3 Prepare the Linux® kernel source code of:

https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Modify,_rebuild_and_reload_the_Linux%C2%AE_kernel#

This tutorial had been test with Ubuntu 20.04, please tell me if you still have some errors after my recommendation.

Regards,

Kevin

Yes , those steps were done and the result shows the error when building the kernel

Hello @debugging​ ,

At this time, we only support up to Ubuntu 20.04 as explained on the wiki: https://wiki.st.com/stm32mpu/wiki/PC_prerequisites#Recommended_PC_configurations

Here, if you have done all the steps, the error seems related to the content that you put in bold.

version `GLIBC_2.33' not found (required by /usr/lib/gcc/x86_64-linux-gnu/11/liblto_plugin.so)

Our Developer Package is made to use glibc v2.33 and by looking at your traces, the v2.34 is installed on your machine.

Can you try to install glibc v2.33 on your machine and make a symbolic link on this version, to use it by default instead of 2.34.

Otherwise, I recommend you if possible to go back to Ubuntu 20.04, because on 21.10, you will surely encounter other problems.

Regards,

Kevin
