I mean it already success with removal of aes and lse, success here: running the binary in raspberry pi 4, and removal of +crc and +neon of course will work, as crc32 and neon supported in by pi4 CPU thus I don't have reason to remove it.
[target.aarch64-unknown-linux-gnu]
linker = "aarch64-linux-gnu-gcc"
rustflags = ["-C", "target-feature=+crc,+neon"]
I will let maintainer to decide, to enable the crc and neon rustflags, or let it empty ☕

@martadinata666 we released new version 0.4.8, i deleted aes and lse, it should work for you.

We are running ARM version in our own cluster. and we tested in macOS M1 CPU. it works.
Can you provide some detail of your CPU?

Ha, our ARM version build with neon feature of ARM CPU. it looks you cpu doesn't support.
You can find detail here:

Yes, it looks your CPU supports NEON https://en.wikipedia.org/wiki/Raspberry_Pi
But in the cargo file we also enabled other features, maybe doesn't support other features. need to check.
You can run rustc --print target-features to check the features support by your cpu.

So, looks it supports every feature we used. but there is no log.
Can you help to build it on Raspberry for test? I have no Raspberry😂

commented on May 28, 2024
That is feature for the target not the capacity of CPU itself. I manually download the binary and run openobserve and it throws illegal instruction, so this is a CPU feature not supported. Thus I'm checking raspberry pi CPU instruction support, results:
ubuntu@rpi4:~/docker/openobserve $ sudo isa-info
Instruction sets:
ARM v8.1 atomics: no
ARM v8.1 SQRDMLxH: no
ARM v8.2 FP16 arithmetics: no
ARM v8.3 dot product: no
ARM v8.3 JS conversion: no
ARM v8.3 complex: no
Cryptography extensions:
AES: no
SHA1: no
SHA2: no
PMULL: no
CRC32: yes
Looking on the .cargo features definition
[target.aarch64-unknown-linux-gnu]
linker = "aarch64-linux-gnu-gcc"
rustflags = ["-C", "target-feature=+aes,+crc,+lse,+neon"]
When AES definitely not supported on raspberry pi, im not really sure about the other instructions crc lse neon, but I will make sure by rebuilding binary ☕

Thanks, after you build succeed, please give us some information, let's try to improve the build progress.

Hi.
The problem is the ldadd instruction.
ldadd instruction is supported in version 8.1 and superior.
The correct Raspberry Pi 4 CPU is Quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5 GHz. https://www.raspberrypi.com/documentation/computers/processors.html#bcm2711 which is ARM v8.0 -> https://en.wikipedia.org/wiki/Comparison_of_ARM_processors#ARMv8-A
Apple M1 is arm 8.5 -> https://en.wikipedia.org/wiki/Apple_M1 Instruction set ARMv8.5-A[5]
On which platform are you compiling it? @hengfeiyang
Thank you @skgsergio @MrMarble for your help
from openobserve.

The only succed binary is when compiled without aes and lse, crc is supported, and also neon even it not listed on the cpu instuctions check command.

So, you can build success only with feature crc, actually, you can delete all features like this:
[target.aarch64-unknown-linux-gnu]
linker = "aarch64-linux-gnu-gcc"
rustflags = []
Try to build again?

@martadinata666 AArch64 represents the state of the ARMv8-A architecture, so the target must be Armv8.0-A.
What is the rust flag to compile to that target?
Additionally @hengfeiyang , you could compile it for the ARM M1 and its optimisations, but I understand it would have to be a separate package.
