run Weston fail on Buildroot

[wG.1]

Hi,

The MP157F-DK2 comes with an SD card attached. Weston (ver 5.0.0) with DRM works well.
But if I want to run Weston(ver 10.0.1) on Buildroot, it will fail.

Do I need to build more packages for Weston?

I am using the version of Buildroot.

a. buildroot: remotes/origin/st/2023.02.6
b. buildroot-external-st: remotes/origin/st/2023.02.2

This is the failure log, and the attachment is the success log of the SD card that comes with the MP157F-DK2.

Would you give an advice?
