cc1: error: ‘-fcf-protection’ is not compatible with this target

-fcf-protection is only available on x86_64 arch, but it looks like you are using x86 arch.

Has been fixed, i needed to use GCC for building hardened GCC, instead of LLVM

Okay, bumping issue

#

GCC fails to build on LLVM profile. Log: https://0x0.st/X0dm.log , portage info: https://bpa.st/QPW7U

@night aurora nah man, with LLVM_SLOT="18" is still fails with llvm 19 ranlib

#

Im doing it with amd64 keyword then

halcyon oracle Oct 30, 2024, 3:51 PM

#

DAFUK

#

IT FAILS WITH THE SAME ERROR EVEN ON FORCED LLVM 18

#

just fun with experiments :)

#

@halcyon oracle which abi use flags do you have enabled?

#

mixed abi fun can become especially fun

#

often resolvable if there is a missing 32bit package however

halcyon oracle Oct 30, 2024, 5:20 PM

#

night aurora <@456226577798135808> which abi use flags do you have enabled?

I dont have any abi use flags set explicitly

#

That error was from different (hardened) gentoo installation, and it was specifically clang's error - i built gcc successfully using gcc

night aurora Oct 30, 2024, 5:21 PM

#

ahh ok :)

halcyon oracle Oct 30, 2024, 5:21 PM

#

But i hate this thing so much already

#

Im gonna migrate to gcc profile lmao

Ranlib spotted

Bumping issue

halcyon oracle Nov 1, 2024, 12:54 PM

#

Issue: gcc compilation fails because llvm-ranlib doesn't accept flag --plugin (llvm profile). It indeed doesn't accept it, because llvm-ranlib is a symlink to llvm-ar. However, even if i use gcc-fallback env overriding path to ranlib, it still fails.

halcyon oracle Nov 1, 2024, 1:11 PM

#

night aurora ahh ok :)

I have an idea!

#

Im dumb

#

gcc-fallback env sets RANLIB to ranlib, but default ranlib is llvm's one

#

So i need to use gcc-ranlib there

#

But stil, why tf it doesn't like llvm's ranlib

#

Yes, now i see it using gcc-ranlib

#

Oh, hm, llvms ranlib is not a symlink to llvm-ar

#

But it really doesn't have --plugin flag

Needs to be reported as a bug

#

A compiler expert is what you need here

spiral relic Needs to be reported as a bug

You think so? Okay, i will prepare info for that

halcyon oracle Nov 1, 2024, 1:41 PM

#

I cant compile even gcc 13 because of the same issue

spiral relic Nov 1, 2024, 1:45 PM

#

Yep report

#

Make sure the reproduce steps are included

halcyon oracle Nov 1, 2024, 1:58 PM

Okay
