My bad. Real issue was missing -ggdb in CFLAGS and producing incomplete debug file. Now it works with multiarch too.

Found out USE=multiarch causing this weird things.

I've installed sys-libs/glibc-2.42-r5:2.2::gentoo with FEATURES="splitdebug"

Unfortunately I can't find glibc function names in the back-traces and can't set working breakpoints to strlen()

strlen@plt redirect to the avx512 implementation.

Is it a bug?

Looks like nightly flag is gone for versions greater 1.85 . Is any way to enable compilation flag -Z ?

Thanks. Some time ago portage require to set SECUREBOOT_SIGN_KEY and SECUREBOOT_SIGN_KEY variables to build secureboot packages.

I've removed these variables and signing works.

After fixing by sbctl sign result is:
# sbverify --list /boot/memtest86plus/memtest.efi64
signature 1
image signature issuers:
- /C=Platform Key/CN=Platform Key
image signature certificates:
- subject: /C=Platform Key/CN=Platform Key
issuer: /C=Platform Key/CN=Platform Key
signature 2
image ...

It's probably attempting verification with the wrong key/certificate (possibly the portage certificate you used is not registered with UEFI/shim yet). Try listing all signatures with "sbverify --list".

# sbverify --list /boot/memtest86plus/memtest.efi64
signature 1
image signature issuers:
- /C ...

I'm using secureboot with own keys.

Portage is not able to sign files.

Hello
I have custom initramfs to activate lvm volume for roof filesystem.

Everything works except warning in systemct:

This is because udev marked this device as not ready for systemd:

Portage is amazing.
Don't have to change ebuild.

Use package.env to affect only sys-libs/glibc.
/etc/portage/package.env: sys-libs/glibc glibc.conf
Use CFLAGS_x86 environment variable to for 32bit target.
/etc/portage/env/glibc.conf:
COMMON_FLAGS="-O2 -pipe -fpic -g"
CFLAGS="${COMMON_FLAGS ...

I need to build sys-libs/glibc with -mstackrealign compiler flag to run old 32bit game.

How to set CFLAGS for glibc and abi_x86_32 only?
