i could try to debug it a bit for you

but how can i compile lfs with a git checkout of lfs-core ?

Canop commented 2 years ago

To start with, lfs is only compatible with linux.

I have no idea how|if WSL manages pseudo filesystems like /proc and /sys/block and I won't install Windows to test.

If you do want to try and maybe make lfs-core compatible with Windows, fetch both lfs and lfs-core repositories, then uncomment the last line in the lfs/Cargo.toml manifest.

At some point you should probably come to the miaou chat.

i don't think it will be be a problem to make lfs-core compatible with wsl

it's basically a linux kernel running an vm

i guess ist a problem with 9p mounts so it should happen on normal linux with a 9p mount to

but i will have i look at it when the lfs-core checkout is working :)

how can i enter the miaou chat ? never used that

i gues ist a room on this website https://miaou.dystroy.org/rooms ?

The best room to speak about lfs in English is https://miaou.dystroy.org/3768

But you may wait to have something running before

As discussed with lordrasmus: the inodes related info given by the pseudo filesystem aren't consistent. I'll change lfs to only load size info and bypass inodes info when those info don't make sense.
