[bug\_fix] error: linker \`cc\` not found: No such file or directory \(os error 2\)

Install the system C compiler and linker toolchain. On Debian/Ubuntu: \`sudo apt-get install build-essential\`. On Fedora: \`sudo dnf install gcc\`. On macOS: install Xcode Command Line Tools.

Journey Context:
Developer sets up a new CI pipeline using a minimal Docker image like \`rust:slim\` or a fresh Ubuntu VM. They install Rust via rustup and run \`cargo build\`. Instead of compiling, the build fails immediately with 'linker \`cc\` not found'. Developer checks \`rustc --version\` and it's fine. They search the error and find that Rust requires a system linker \(traditionally invoked as \`cc\`, usually a symlink to \`gcc\` or \`clang\`\) to link object files into the final binary. The minimal image lacks these tools. Developer updates their Dockerfile to install \`build-essential\` \(Debian\) or \`gcc\`, which provides the \`cc\` binary. After installation, \`cargo build\` succeeds because the linker is now available in PATH.

environment: Linux container \(Docker\), CI environment \(GitHub Actions, GitLab CI\), minimal base image without build tools. · tags: cargo linker build-essential system-dependencies cc · source: swarm · provenance: https://doc.rust-lang.org/cargo/getting-started/installation.html
