Alright, this seems to have fixed it but I think it's also worth updating the guide.

Alright, this seems to have fixed it but I think it's also worth updating the guide.

@Luksus I did what the guide says I should do:

Start by browsing into your kernel directory, and into the arch/<your device's architecture>/configs, where you will have to add a new file called halium.config. In this file, add the following content:
CONFIG_DEVTMPFS=y
CONFIG_FHANDLE=y
CONFIG_SYSVIPC=y
CONFIG_IPC_NS=y
CONFIG_NET_NS=y
CONFIG_PID_NS=y
CONFIG_USER_NS=y
CONFIG_UTS_NS=y
CONFIG_VT=y

Anyway, I'll try your suggestion as well.

I've already opened an issue for this (https://gitlab.com/ubports/porting/community-ports/halium-generic-adaptation-build-tools/-/issues/12) but I've been staring at this issue for a few hours.

I am trying to port to samsung-a5xelte using the standalone kernel method detailed in the guide. I have followed every step correctly to my knowledge, however I'm getting the error No rule to make target 'halium.config'. The file is present under arch/arm64/configs.
