Created attachment 670118 [details] `emerge -vat glibc` and `emerge --info` Trying to upgrade glibc, I'm getting this failure: running configure fragment for sysdeps/unix/sysv/linux checking installed Linux kernel header files... missing or too old! configure: error: GNU libc requires kernel header files from Linux 3.2.0 or later to be installed before configuring. The kernel header files are found usually in /usr/include/asm and /usr/include/linux; make sure these directories use files from Linux 3.2.0 or later. This check uses <linux/version.h>, so make sure that file was built correctly when installing the kernel header files. To use kernel headers not from /usr/include/linux, use the configure option --with-headers. * ERROR: sys-libs/glibc-2.32-r2::gentoo failed (configure phase): However: beryl ~ # equery l linux-headers * Searching for linux-headers ... [IP-] [ ] sys-kernel/linux-headers-5.4-r1:0 beryl ~ # cat /usr/include/linux/version.h #define LINUX_VERSION_CODE 328704 #define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c)) (328704 corresponds to 5.4.0) I've attached a full log of the emerge output and of emerge --info I am not confident that this isn't something specific to my system somehow - I don't have another system to try to reproduce this on right now. But it seemed worth reporting just in case, as I'm not sure how I could have broken this detection. :)
Also, the pre-detection seems to look fine (from the log): * Checking running kernel version (5.4.60-gentoo >= 3.2.0) ... [ ok ] * Checking linux-headers version (5.4.0 >= 3.2.0) ... [ ok ] So I don't know why the later check is failing, it seems weird.
Don't trust equery: emerge -pvO sys-kernel/linux-headers. Any better if you reinstall them, too?
(In reply to Sam James from comment #2) > Don't trust equery: > emerge -pvO sys-kernel/linux-headers. Sorry and thanks :) That shows the same though: beryl ~ # emerge -pvO sys-kernel/linux-headers These are the packages that would be merged, in order: [ebuild R ] sys-kernel/linux-headers-5.4-r1::gentoo USE="-headers-only" 0 KiB Total: 1 package (1 reinstall), Size of downloads: 0 KiB > > Any better if you reinstall them, too? I did try reinstalling linux-headers to no avail. Happy to try anything else, or give any further info to help debug. Just let me know what you need :) For now, I am fine masking the update so I can update the rest of my system, so this isn't critically blocking me on anything.
Can you extract `config.log` from the glibc build directory? Hopefully it will mrovide more detailed error message on what went wrong.

Good call- I found the config.log and earlier in it (above the error in my original report), there was another error (permissions due to my ccache configuration). Fixed that and it seems to be building fine now. I think the linux-headers error was just a red herring. :( Sorry for the trouble and thanks for the quick responses!
