# `mix emerge.build_info`
[🔗](https://github.com/emerge-elixir/emerge/blob/v0.5.1/lib/mix/tasks/emerge.build_info.ex#L1)

Reports the native build configuration without compiling or loading the NIF.

    mix emerge.build_info
    mix emerge.build_info --backend headless:opengl --target aarch64-unknown-linux-gnu
    mix emerge.build_info --systems
    mix emerge.build_info --profiles

If Emerge has not compiled yet, run the standalone equivalent:

    elixir deps/emerge/scripts/build-info.exs

The Mix task reads application configuration. The standalone script reports
environment defaults unless explicit `--backend` options are supplied. Neither
command probes devices or verifies that release archives have been published.
