• Node JS version (node -v): v16.20.0
• Operating System: Alpine Linux v3.16
• Blockscout Version/branch/commit: [5536b12]
• Archive node type && version (Erigon/Geth/Nethermind/Ganache/?):

Steps to reproduce

Runing: mix do deps.get, local.rebar --force, deps.compile, compile

Expected behaviour

Should raise no error

@spilin would you change to build Blockscout with Docker image? Current image (master tag) is built on top of Alpine 3.18 https://github.com/blockscout/blockscout/blob/c46aa15d0bcb1d2a6aab15a9db03409ea46b4bd3/docker/Dockerfile#L1 and has no issues with precompiled NIF.

I will do that when will get a chance. As of now I still get:

Generated rustler_precompiled app
==> ex_secp256k1
Compiling 2 files (.ex)

== Compilation error in file lib/ex_secp256k1/impl.ex ==
** (RuntimeError) precompiled NIF is not available for this target: "x86_64-alpine-linux-musl".

But I resolved this by using:

export EX_SECP256K1_BUILD=true
export EXKECCAK_BUILD=true
export TARGET_VENDOR=unknown

So if it's only me who gets this error - you can close it.
