Thanks peter.
What's mean Buildroot 2020.02.8-dirty?

About python37, yes I add this custom package but like you see I didn't
select it.
this config is without livdevdev and it compile right. but if I select it I
had th error I gave (do you think it could be a problem if I not set
libdevdev, I realy not sure I need it, sorry I didn't completly setupp this
buildroot jus modify some aspect and I am far to master all).

But its is strange that I have BR2_PACKAGE_PYTHON not set.
I will look later (I am not on my linux computer), I think I even havent
pithon item in menu-config...
Is this mean I have a problem with python dependencies ? I will check the
dependencies logic.

Peter, Its very strange that at your side you could compile with libdevdev
set and not me. Do you have an idea wher I could search?

Many thanks for helping.

Regards.

Emmanuel
