I have been following this guide with some changes made to account for the use of fedora instead of arch for the original asahi install following this pr. I have reached step 6, which involves simply cloning this repo and running the contained "install.sh" script. However, the kernel compilation exits with an "error 2" which I have no idea how to deal with.

output of install.sh:
https://pst.innomi.net/paste/ynkyjwsayq5ypxzt3p3gdye6

kernel config (copied from running kernel by install.sh):
https://pst.innomi.net/paste/ha4soboa3kfzbz96a3j4hoav

lscpu:
https://pst.innomi.net/paste/jygpsvthgr5cqa7bjoj2heff

Any pointers? I believe it's a problem with the kernel config as it is copied from a prebuilt fedora kernel, however I have also experimented with custom kernel configs to the same result. I understand there are known issues with gentoo asahi right now but I am completely stuck.

m1v,

Welcome to Gentoo Forums !

All your links give a 404, just use a pastebin service.

Error code 2 usually says that a file was not found.

In addition to the kernel configuration, the output of "dmesg" would also be important (after you have started with a boot CD) because we get important system information there. An additional "lspci -nnk" would also be helpful ( https://wiki.gentoo.org/wiki/User:Pietinger/Overview_of_System_Information ).

In the context of errno, yes, 2 is ENOENT ("No such file or directory"). However, from frequent reports of kernel compilation failures, I suspect that in this case the OP is referring to output like this:
Code:
$ echo 'target:
        echo "Failing now ..."; exit 2' | make -f -
echo "Failing now ..."; exit 2
Failing now ...
make: *** [/tmp/GmwwJpSs:2: target] Error 2
That is, make is merely reporting that a recipe exited with a status code of 2. It may not have anything to do with a missing file. If we could see the build log, we could check this, but as pietinger notes, the links all return 404.

I have fixed the pastebin links so the logs should be visible now. I will update with extra system information soon.

So your real error is:
Code:
  AR      built-in.a
  AR      vmlinux.a
  LD      vmlinux.o
  OBJCOPY modules.builtin.modinfo
  GEN     modules.builtin
  MODPOST Module.symvers
  CC      .vmlinux.export.o
  UPD     include/generated/utsversion.h
  CC      init/version-timestamp.o
BTF: .tmp_vmlinux.btf: pahole (pahole) is not available
Failed to generate BTF for vmlinux
Try to disable CONFIG_DEBUG_INFO_BTF
make[2]: *** [scripts/Makefile.vmlinux:36: vmlinux] Error 1
make[1]: *** [/usr/src/linux-6.6.0_p15-asahi/Makefile:1165: vmlinux] Error 2
make[1]: *** Waiting for unfinished jobs....

There's a helpful hint there as well. Too bad the automation makes it difficult to change.

Maybe insatlling dev-util/pahole first may fix it.

Moved from Other Things Gentoo to Gentoo on ARM.

Apple Silicon is aarch64, so belongs here.

i merged dev-util/pahole, which fixed the previous issue and allowed me to get noticeably further through the compilation than before.

however, i have reached a new issue. during compilation, i receive a few dracut errors complaining about being unable to install systemd.

i would strongly prefer not to use systemd, but i was unable to find the options in menuconfig to change the init system.

i started using this fork of the scripts included in the asahi linux wiki as they have been updated to support fedora. also followed the advice of this thread and added "omit_dracutmodules+=" systemd " to my dracut config, but this had no effect.

dmesg:

lspci -nnk:
