A failure occurred in package_linux516-tkg-bmq-headers()

[Shadow12347]

I've been able to compile the kernel many times across many different versions, and I am now trying to compile 5.16. It runs through everything like normal but fails every time near the end with this error:

==> Starting package_linux516-tkg-bmq-headers()... -> Installing build files... install: cannot stat 'tools/bpf/resolve_btfids/resolve_btfids': No such file or directory ==> ERROR: A failure occurred in package_linux516-tkg-bmq-headers().

I tried across commits and still am not able to get past this issue on 5.16, while 5.15 works just fine. I'm using gcc with -O3 and ZEN3 (which has never caused an issue for me).

I was able to resolve this by commenting this line out in the PKGBUILD:

install -Dt "$builddir"/tools/bpf/resolve_btfids tools/bpf/resolve_btfids/resolve_btfids

I then received some errors about winesync files being in conflict with my 5.15 tkg install. So I rebooted into a stock kernel, uninstalled 5.15 tkg, and then installed 5.16 tkg, which is now running successfully.

This issue should be fixed as that line you commented out is only run on 5.16+

I'm compiling 5.16 (and running 5.16), and I am still receiving this error. But commenting out the if statement for btfids resolves it.

I see, does it happen with other schedulers for example ? Something is off as you seem to be the only one who has this issue ?

[Shadow12347]

Yeah, I have a cacule version alongside the bmq one that I used for testing, and it happens on both. That said, if it isn't affecting anyone else, I already found a workaround, and it shouldn't be an issue once I move to 5.17.

It's not a scheduler issue. You have some part of the bpf framework enabled that requires the btf info, but the kernel is compiled without the said info.

For the 'resolve_btfids' tool to work, the kernel needs to be compiled with 'DEBUG_INFO_BTF=y'.

CONFIG_DEBUG_INFO_BTF:

Generate deduplicated BTF type information from DWARF debug info. Turning this on expects presence of pahole tool, which will convert DWARF type info into equivalent deduplicated BTF type info.
