Compiling issues

File is not found, even if it is in the kernel

The only ways to fix it is to change something, change the kernel or change something in the kernel. I could've also added untar/unzip on the depends.

ANDROID_MAJOR_VERSION

I don't know where to also put it. I've done it 3 times in the APKBUILD of the device configuration, but it still refuses to let me build or edit the kconfig.

Issues

Vendor kernel

It might not be made.. I don't even know what vendor files are important!

pmbootstrap not letting me set the desktop environment, build size and other stuff

The alpha version isn't suitable. I had to downgrade to 2.3.1 to have it work
