[Buildroot] Unable to build Buildroot

[Shérab]

Dear all,

I am not able to build Buildroot any longer, although it used to work
and I can't remember of any change on the machine used tobuild.

Here is what happens just before the failure:

Your host seems to have glibc 2.27 installed. In this version glibc added 
copy_file_range() which collides with a local definition of the same symbol in 
e2fsprogs. This issue is fixed in e2fsprogs commit 01551bdba1 (misc: rename 
copy_file_range to copy_file_chunk), which is included in version 1.43.8. The 
latest Buildroot release, 2018.02, has 1.43.9.

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.

which is using a development version of Buildroot between 2017.11 and 2018.02:
2017.11-354-g85e08bf

It seems to me the Makefile for brlpi does the right thing for:
1) make clean
  - deinit the submodule buildroot
  - remove the Buildroot output dirs 
2) make
  - init/update the submodule buildroot
  - configure the builds as out-of-tree
    (http://nightly.buildroot.org/#_building_out_of_tree)
  - call make inside the output dirs

But if it fails for you, you could create an "issue" in brlpi github page.

So you are working to update the Buildroot version for a br2-external.
It's possible you need to do other changes to the br2-external as well.

This is the package defined by the br2-external.

> 'package/brltty/'. Arr?t.

This is the package defined by Buildroot.
It was not there in commit 85e08bf, but it is there at 2018.02 as the patch
sent by Mario adding the package was applied.

Tips:
 - read the br2-external section in the manual:
   http://nightly.buildroot.org/#customize
 - check the diff between the two brltty packages (the one from Buildroot and
   the one from br2-external);
 - remove the package from br2-external and do a clean build to check. If is
   breaks, you probably will need more changes to the br2-external.

Dear Ricardo,

Many thanks for your response!

I did not realise brltty got upstreamed, that was part of what I missed
so many thanks for having made me aware of that.

Cheers,

Sh?rab.

Dear all,

So, I updated the buildroot submodule properly and removed brltty as an
external package.

I am now facing another compile problem, with qemu I think:

I tried to disable the host qemu in make menuconfig but that was not
possible.

I also discovered that the host qemu seems to be selected by emacs but I
don't understand what's the linkbetween the two (emacs is provided in
the br2-external tree).

Any hint?

Thanks,

Sh?rab.
