Which version of clang is being used here? I see you have 2 versions installed.
(In reply to Mike Gilbert from comment #1) > Which version of clang is being used here? I see you have 2 versions > installed. Clang 17, however the same error is present when using CC="clang-16".
There seems to be some clue here: https://github.com/kraj/meta-clang/blob/master/conf/nonclangable.conf in that they've added the following: # TOPDIR/build/tmp/work/core2-32-yoe-linux/gnu-efi/3.0.17-r0/gnu-efi-3.0.17//lib/ctors.S:11:41: error: expected the entry size # .section .init_array, "aM", @init_array # ^ CFLAGS:append:pn-gnu-efi:toolchain-clang = " -no-integrated-as" I've tried adding that to Make.defaults via a user patch, and changing both CC and BULDCC to "clang -no-integrated-as". I've also tried changing AS from AS=llvm-as to AS=as but none of these seem to work.
I've also done some more digging, gnu-efi-3.0.15 builds fine, and it looks to be that the ctors.S file was added in 3.0.17. Looks like the GNU assembler accepts these without a defined size but the LLVM assembler doesn't. Unfortunately that's where my expertise ends...

According to https://sourceware.org/binutils/docs/as/Section.html, the entsize argument is supposed to be required by GNU AS as well, but clearly this isn't enforced. > If flags contains the M symbol then the type argument must be specified as well as an extra argument—entsize—like this: > .section name , "flags"M, @type, entsize
Seems like this was already fixed upstream actually, will backport. https://sourceforge.net/p/gnu-efi/code/ci/97499a0cf265bf2d515bfcab99349ce00ecf2662/

Haven't had the time to look into it yet.
I looked into this issue and it seem the llvm toolchain defaults to `-zrelro` where as bfd defaults to `-znorelro` I have not been able to make gnu-efi use my own cflags so if someone could test with these it should make it possible to make gnu-efi build
Created attachment 881261 [details] working build log for clang-first system I have backported the referenced patch manually (I couldn't find a way to download it) and it seems to work for me. I have a clang-first system though, perhaps that plays a role. I have attached the working build log in case you want to check the actual build commands. This is how my system is set up w.r.t.

(In reply to Fabio Scaccabarozzi from comment #10) > I have a clang-first system though, perhaps that plays a role. I am on a fresh install using a "stage3-amd64-llvm-systemd-mergedusr" archive and got the same error messages mentioned above after applying the already mentioned patch. I then noticed that Fabio is using the following linker in the provided logs: "x86_64-pc-linux-gnu-ld". I then tried: LD=ld.bfd emerge gnu-efi and got another error: llvm-objcopy: error: invalid output format: 'efi-app-x86_64'. Looking at other bugs i saw that switching to binutils objcopy would enable me to install gnu-efi: LD=ld.bfd OBJCOPY="objcopy" emerge gnu-efi
