Pmbootstrap: Device tree headers not found

[Decatf]

I'm trying to compile a kernel that uses appended device tree. pmbootstrap fails to compile the device tree blobs with the following error.

Here is the device specific package I'm working on.

I've been porting newer kernels for this device. This kernel compiles in the Android build env and boots Android so it is a known working kernel.

The .zip files from github don't contain the symlinks in the kernel source. if you change the extension to .tar.gz in your linux package APKBUILD then it should work

I've tested your branch with modifying the source as @MartijnBraam said. This fixes the No such file or directory error, but later the compilation fails at compressing the kernel. It finally runs through when adding xz to the makedepends= in the APKBUILD to fix that.

I've added two sections in troubleshooting about these issues, which you can read if you're interested in more details/alternative workarounds.

Thanks for tying out pmbootstrap and starting a new port!

Using tar.gz worked. I am able to boot the kernel but nothing else happens. The kernel log shows all the driver initialization and then it sits idle at the original device boot logo. I guess that's some other issue.

I did not get any error with compressing the kernel. Everything compiled without error after using tar.gz instead of zip.

That is some progress at least :) I recommend joining the matrix/irc channel, so we can help you more directly.

Have you adjusted your APKBUILD to use the zImage-dtb file, as described in the guide? If not, this could cause what you are describing.
