glib meson error: ERROR: <ExternalProgram 'python3' is not a valid python or it is missing setuptools

[FPini.1]

I have been trying to compile an image in Yocto with a custom machine to load my own device tree, but when trying to compile I always get the same error, here is a log:

Log data follows:

thanks for your help.

Hi @FPini.1​ ,

Did you install "Python3" on your station ?

Please refer to article https://wiki.st.com/stm32mpu/wiki/PC_prerequisites to check all requested package for Distribution support.

I am hitting the exact same issue when I am compiling the STM32MP1's distro off https://github.com/STMicroelectronics/oe-manifest/tree/dunfell branch's manifest.

This is not a host PC installation issue rather a Yocto build system issue.

[Olivier GALLIEN]

Hi @ZZhao.1​ ,

What's you host station OS ?

Could you provide also what is printed out after execution of envsetup.sh ?

Thanks

I was trying to fix this problem by modifying the order of the layer in bblayers.conf file and it worked when I put the meta, meta-poky, and meta-oe at first, It didn't give me a compile error but in the end, it didn't generate me the uinitrd causing the openSTLinux couldn't boot correctly.

Thanks for your attention.

Hi,

is there any solution about this issue?

I have the same error running on Ubuntu 20.04, running "bitbake -c populate_sdk st-image-weston" from openstlinux-5.10-dunfell-mp1-21-07-21 distro, with following configuration

DISTRO=openstlinux-weston MACHINE=stm32mp1

Thanks,

Michele

Hello,

please cherry-pick this patch (from v3.1.0) on v3.0.2 version: https://github.com/STMicroelectronics/meta-st-stm32mp/commit/0099ab38118ed2735f0708b1080bb50d12955dfe

So "classes/python3native.bbclass" file has to be deleted

[Bernard PUEL]

v3.0.3 delivered to correct this issue: https://github.com/STMicroelectronics/oe-manifest/tree/openstlinux-5.10-dunfell-mp1-21-11-30

But better take v3.1.0 if you can (latest ecosystem delivery).

Still investigations are ongoing to understand why the issue was not seen internally before the release (during validation tests).
