Summary of Docker build error

- Failing step (command/step)
  - [6/6] RUN cargo build --release

- Exact error message and exit code
  - exit code: 101
  - Error flow excerpt:
    - error: failed to run custom build command for `frida-gum-sys v0.17.1`
    - Caused by:
    - process didn't exit successfully: `/workspace/target/release/build/frida-gum-sys-6c0689b87c024774/build-script-build` (exit status: 101)
    - --- stderr
    - thread 'main' (12600) panicked at /usr/local/cargo/registry/src/index.crates.io-1949cf8c6b5b557f/bindgen-0.72.1/lib.rs:616:27:
    - Unable to find libclang: "couldn't find any valid shared libraries matching: ['libclang.so', 'libclang-*.so', 'libclang.so.*', 'libclang-*.so.*'], set the `LIBCLANG_PATH` environment variable to a path where one of these files can be found (invalid: [])"

- Missing packages/files mentioned
  - libclang libraries are missing / not found in the environment (required by bindgen during the frida-gum-sys build)
  - LIBCLANG_PATH needs to point to a valid libclang library location

- Version/mismatch information
  - Docker build uses Rust nightly: nightly-2026-02-24-x86_64-unknown-linux-gnu
  - Rust toolchain reported: rust version 1.95.0-nightly (b3869b94c 2026-02-23)
  - Frida gum devkit download is attempted as part of frida-gum-sys build (log shows: "Frida gum devkit not found, downloading from ..."), but the failure occurs before successful libclang resolution

Notes:
- The root cause is missing libclang for the bindgen step in the frida-gum-sys crate, causing cargo build to fail with exit code 101.

  - During builder step 6/7, rustc and cargo were not found (bash: line 1: rustc: command not found; bash: line 1: cargo: command not found), indicating the Rust toolchain was not available to produce the mirrord binary

- Version mismatch info
  - Builder image uses rust:1.72-bullseye (Debian Bullseye)
  - Runtime image uses Debian bookworm-slim
  - The build steps then pull/install packages from bullseye (older Debian) while the runtime base is bookworm (newer Debian), indicating a cross-version mismatch between builder and runtime environments

thoughtI am going to replace the Dockerfile with a multi-stage build that mirrors the builder and runtime flow used in mirrord/agent/Dockerfile, targeting building the mirrord-agent from source and producing a runnable container. Then I will run the build verification.

Summary of Docker build error

- Exact error message and exit code
  - Exit code: 101
  - Error (from bindgen during cargo build):
    thread 'main' (11025) panicked at /usr/local/cargo/registry/src/index.crates.io-1949cf8c6b5b557f/bindgen-0.72.1/lib.rs:616:27:
    Unable to find libclang: "couldn't find any valid shared libraries matching: ['libclang.so', 'libclang-*.so', 'libclang.so.*', 'libclang-*.so.*'], set the `LIBCLANG_PATH` environment variable to a path where one of these files can be found (invalid: [])"

- Failing command/step
  - [builder 6/7] RUN cargo build --release -p mirrord

- Missing packages or files mentioned
  - libclang libraries are not present (bindgen cannot locate libclang)
  - LIBCLANG_PATH is not set
  - The runtime apt-get install in the Dockerfile installs ca-certificates, libssl3, openssl, but not libclang/clang dev libraries

- Version mismatch info
  - The failure is tied to bindgen version: 0.72.1 (lib.rs:616:27). The issue is missing libclang libraries, not a direct code version mismatch. No other explicit version mismatches shown.
