Okay thanks a lot!

I am facing another problemnow which may be slightly off-topic here but
let me try.

The buildroot I am using is a submoduleof this repository:

https://github.com/mlang/brlpi

Although I did makeclean etc., the buildroot submodule was not updated
and I was not able to find a way to ask git to update it through a
submodule subcommand.

So I went to the buildroot subdirectory, did a git fetch and then
checked out 2018.02, which worked.

But then when I tried to run make cleand and make again to rebuild my
image,

quickly I got the following error message:

umask 0022 && make -C /home/shindere/src/brlpi/buildroot O=/home/shindere/src/brlpi/brlpi0w/.
/home/shindere/src/brlpi/package/brltty/brltty.mk:104: *** Package
'brltty' defined a second time in
'/home/shindere/src/brlpi/package/brltty/'; previous definition was in
'package/brltty/'. Arr?t.

I'm sory but I have no idea how to deal with this. Any suggestion would
be welcome.

Thanks,

Sh?rab.
