Cross compiling for arm

[Rikorose]

I want to cross compile from linux x64 to aarch64. On the x64 machine I put bin-target-triple="aarch64-unknown-linux-gnu" and compiled frontend and server using: LEPTOS_BIN_CARGO_COMMAND=cross cargo leptos build --release. This works so far.

I am not sure how to correctly execute the resulting binary on the aarch64 machine. I tried to directly call the executable: ./target/aarch64-unknown-linux-gnu/release/leptos-binary-test:

It looks like you're trying to compile Leptos without the LEPTOS_OUTPUT_NAME environment variable being set. There are two options
 1. cargo-leptos is not being used, but get_configuration() is being passed None. This needs to be changed to Some("Cargo.toml")
 2. You are compiling Leptos without LEPTOS_OUTPUT_NAME being set with cargo-leptos. This shouldn't be possible!

It seems, that some config is not correctly passed to the binary also since the port is the default port (which I modified).

Or is there some way to run the cross compiled binary with cargo leptos?

I ran into the same issue, I solved it by changing get_configuration(None) to get_configuration(Some("Cargo.toml")) near the root of the program as described in the error message, then also copying Cargo.toml to the same directory as the file.

I get the same message at runtime even that when cross-compiling with cross I set LEPTOS_OUTPUT_NAME env var myself.

Plus, it also builds the frontend to fetch the wasm file with _bg.wasm suffix.

The issue seems to be that within cross environment is not seeing the LEPTOS_OUTPUT_NAME env var I was setting, I just fixed it by adding the following to my Cargo.toml file:

[package.metadata.cross.build.env]
passthrough = ["LEPTOS_OUTPUT_NAME=<desired-output-name>"]

For some reason other values are being set correctly, like LEPTOS_SITE_ADDR seems to be picked up with the value set to site-addr in my Cargo.toml.
