I tried to set up a crossdev for a Raspbery Pi 4 on a desktop machine I had. It worked (sort of) but I had to make a bunch of changes to where now today when I tried to update cross-glibc failed. So I tried to just reset back to a stage3 tarball and redo it but it is still failing.

/var/log/portage/cross-aarch64-unknown-linux-gnu-info.log:

https://0x0.st/8XgU.log

/var/log/portage/cross-aarch64-unknown-linux-gnu-glibc.log:

https://0x0.st/8XgD.log

It compiles that I'm trying to compile glibc without optimisations but I have

cat /usr/aarch64-unknown-linux-gnu/etc/portage/make.conf |grep FLAGS
CFLAGS="-mcpu=cortex-a72 -O2 -pipe"
CXXFLAGS="${CFLAGS}"

I tried searching on bugs.gentoo.org but I couldn't find anything. Not sure where the problem is. Any suggestions?

Edit:

emerge -pqv '=cross-aarch64-unknown-linux-gnu/glibc-2.40-r8::crossdev'

I've been trying to learn ARM assembly for my m1 MBA by following along with this book and accompanying GitHub page updating it for Apple silicone. Unfortunately, I am running into the error "unknown AArch64 fixup kind!" when I try to use ADR or ADRP (LDR is not allowed on Apple silicone afik). So, If anyone knows why this error is popping and/or how to fix it, that would be awesome.

The Code:

.global _start
.align 2    //needed for mac os
_start: mov x0,#1           //stdout = 1
        adr x1, helloworld  //string to output
        mov x2, #16         //length of string
        mov x16, #4         //write sys call value
        svc 0               //syscall

//exit the program
mov x0, #0
mov x16, #1
svc 0
.data
helloworld: .ascii "Hello World!\n"

command to replicate the output:

as -o HelloWorld.o HelloWorld.s
