Musl-gcc in rust based Netlify Functions

Build problems? Link or paste the FULL build log & build settings screenshot
I am building a rust based netlify function that has as one of its dependencies the openssl-sys.

When I build that project locally, I don’t have any problems, but when deploying that to netlify I get the following output:

Is it possible to have installed musl-gcc in the host instance that runs the functions?

Hello, I'm trying to compile a rust lambda function using the aws-sdk-rust but h…aving issues with it. Here's some info: rust code: ```use aws_sdk_dynamodb::{Client, Error}; use lambda::{handler_fn, Context}; use serde_json::Value; type Error = Box<dyn std::error::Error + Sync + Send + 'static>; #[tokio::main] async fn main() -> Result<(), Error> { lambda::run(handler_fn(handler)).await?; Ok(()) } async fn handler(event: Value, _: Context) -> Result<Value, Error> { let shared_config = aws_config::load_from_env().await; let client = Client::new(&shared_config); let req = client.list_tables().limit(10); let resp = req.send().await?; println!("Current DynamoDB tables: {:?}", resp.table_names); Ok(()) } ``` Cargo.toml: ``` [package] name = "lambda_sdk" version = "0.1.0" edition = "2018" [dependencies] lambda = { git = "https://github.com/awslabs/aws-lambda-rust-runtime/", branch = "master"} serde_json = "1.0" aws-config = { git = "https://github.com/awslabs/aws-sdk-rust", tag = "v0.0.17-alpha", package = "aws-config" } aws-sdk-dynamodb = { git = "https://github.com/awslabs/aws-sdk-rust", tag = "v0.0.17-alpha", package = "aws-sdk-dynamodb" } tokio = { version = "1", features = ["full"] } ``` compilation (all worked before changing the lambda function to add the SDK): 1) cross-compilation cargo build --release --target x86_64-unknown-linux-musl 2) docker linux rustup target add x86_64-unknown-linux-musl && cargo build --release --target x86_64-unknown-linux-musl 3) cdk synth myStack ``` import * as cdk from '@aws-cdk/core'; import * as lambda from '@aws-cdk/aws-lambda'; export class LookupIAMRoleStack extends cdk.Stack { constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) { super(scope, id, props); const target = 'x86_64-unknown-linux-musl'; new lambda.Function(this, 'lambdaSDK', { code: lambda.Code.fromAsset('lambda/lambda_sdk', { bundling: { command: [ 'bash', '-c', `rustup target add ${target} && cargo build --release --target ${target} && cp target/${target}/release/lambda_sdk /asset-output/bootstrap` ], image: cdk.DockerImage.fromRegistry('rust:1.55-slim') } }), functionName: 'TestLambdaSDK', handler: 'main', runtime: lambda.Runtime.PROVIDED_AL2 // defines an AWS Lambda resource }); } } ``` all generate the exact same error message (with different path obviously): ```....

Hey @morenol

As best my knowledge, and as per Functions Documentation Rust is not (currently) a supported functions language (on Netlify)—only JS, TS, and Go are.

morenol · April 7, 2022, 11:27pm

There is some functionality that is experimental

morenol · April 7, 2022, 11:28pm

In any case, is it possible to install custom OS packages for the build process?

If there’s a brew package for that, then sure:
