build error when creating filesystem on part 2

No really suggestions.
This happens on every build?

I have the same issue with fresh git

how did you solve the issue ?

Try using newer populatefs. In LibreELEC folder run

wget -O populatefs.patch https://github.com/vpeter4/LibreELEC.tv/commit/b6cfd290a18ff761afe1c51984baf2dd319e88b4.patch
patch -p1 <populatefs.patch
PROJECT=... ARCH=... scripts/clean populatefs
PROJECT=... ARCH=... make image

thank you. I will try

Nevertheless, even with that error can I use already prepared tar build in target folder ?

I think tar file is fine in this case.

unfortunately , even with your patch I have the same issue

Then I'm not sure what it could be.

Would be possible to give me ssh access to your box so I could investigate myself?

Good evening,

If someone figures this out, I'd love to hear how this got solved. I poked around trying to find what could be causing this but my knowledge of the code for LibreELEC is very limited. I tried to compile for the three platforms I have here (RPi2, Imx6 and Odroid C2) and they all seem to end with the same error as well. I got the source out of git, if that helps.

For the time being, it's not s showstopper as I use the tar file to update an existing install.

Thanks
P.

PRochefort or anyone else with this issue: can you come to IRC to talk about it (find vpeter )? And we will try to figure out what is going on.

Our dear user ozolli kindly gave me access to his build box and I successfully identified the issue. He is using Debian GNU/Linux stretch/sid.
LibreELEC is using host tools for formatting EXT4 partition. And Debian is using newer version of ext2 filesystem utilities
which supports some new filesystem feature called metadata_csum. But e2fsprogs 1.42.13 used by LibreELEC doesn't understand that. And populatefs fail at the end.

There are 3 possible solutions:
1.) If whole build is already done then mke2fs should disable some features (64bit,metadata_csum).
The line should look like this in file scripts/mkimage:

mke2fs -F -q -t ext4 -m 0 -O ^64bit,^metadata_csum "$LE_TMP/part2.ext4"

2.) For new builds e2fsprogs package should be bumped to 1.43.3
file packages/sysutils/e2fsprogs/package.mk
3.) remove feature metadata_csum from /etc/mke2fs.conf
for advanced users only!

I suppose you'll make a PR to bump e2fsprogs?

Already done. But will be available only in LibreELEC v9 - just in case. We don't want to break something so late in v8.

vpeter,

Your solution is perfect. It fixes my build. I will modify the script and rebuild for all platforms. Thank you so much for finding the problem.
