Build error when cross compiling quantization for arm

[chiru-arh]

I'm getting below error when cross-compiling quantization for arm64.

warning: [email protected]: tools/arm-linux-gnueabi-gcc-9.2/bin/arm-linux-gnueabi-ar: 
'app/target/arm-unknown-linux-gnueabi/debug/build/quantization-84a087b7ec779edc/out/libsimd_utils.a': No such file
error: failed to run custom build command for quantization v0.1.0 (https://github.com/qdrant/quantization.git#9395db62

How can I fix this

Is it possible that you've configured cross-compilation incorrectly? We're doing cross compilation in Qdrant as well targeting ARM64 without issues.

A bunch of architecture specific code is gated by specific platform attributes. It looks like something is going wrong here.

Could you share the command you use for cross compilation?

@timvisee , thank you for the reply. did you try building qdrant for ARM(not ARM 64) specifically? I didn't see any condition here for arm

@timvisee
I am able to do cross compilation for aarch64 but for arm it is failing with same as mentioned on this issue.
Can you please help on this?

Hello @IvanPleshkov ,
Any suggestion for this issue.
Is ARM build is possible for quantization ?

Thanks for the issue! I gonna remove all C code from repo and this issue will be fixed (draft PR #26)
