Created attachment 666542 [details] build.log Hi, Following emerge @system/@world because of GCC update, =sys-libs/efivar-37 now fails to link on my ia64 workstation, though the root cause is unclear from the log files. This isn't a GCC regression, as switching back to the previously used GCC compiler doesn't help. Émeric

Confirmed on guppy. binutils-2.34 works, binutils-2.35.1 fails.
Looks like it's a side-effect of -specs=/var/tmp/portage/sys-libs/efivar-37/work/efivar-37/gcc.specs trying to inject '-z relro' (removing it from spec removes an error). This probably means that > /usr/lib/gcc/ia64-unknown-linux-gnu/10.2.0/../../../../ia64-unknown-linux-gnu/bin/ld: warning: -z relro ignored is treated as error instead of warning.
Ah, it comes from efivar/src/include/gcc.specs: %{!static:--fatal-warnings}. It's a -Werror equivalent for linker. Probably should be removed or spec file to be fixed not to user relro on some targets.
The problem does not occur on amd64, so I assume this behavior is specific to the ia64 linker. Please report the problem upstream. https://github.com/rhboot/efivar
https://patch-diff.githubusercontent.com/raw/rhboot/efivar/pull/164.patch should drop the warning. Émeric, can you check if it helps to build sys-libs/efivar and produce working bootloader?

Thanks for the patch Sergei. Yes, it does allow to successfully compile/link sys-libs/efivar and produces /usr/bin/efivar binary that seems to work as expected. Just a question: Isn't dropping fatal warnings a little bit unsafe? Maybe for the other non-exotic platforms? If I understand correctly, the issue is with -z relro here. Wouldn't it be safer to drop this argument (though I don't know its exact purpose, I recognize)?
I would say turning blanket warnings to errors is useful for development. But not for final releases. Enabling more specific warning to errors is usually less fragile. '-z relro' is interesting: it's default-on for binutils for quite a while (where implemented). So it might be ok to drop the option entirely from the spec. binutils could be compiled with --disable-relro to override the default. But perhaps it's not important to move relocations out to a separate page for efivar specifically. Any solution should be fine for ia64 as it does not implement relro. Not sure about the other targets.
Please feel free to push the patch in Gentoo.
