Cause (Documented platform behavior): Rust relies on an external linker (default `cc` on Linux); rustc emits LinkerNotFound when the linker binary cannot be executed.
Fix status: documented_behavior
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/rust-lang/rust/main/compiler/rustc_codegen_ssa/src/diagnostics.rs (official_docs, unknown, documented_behavior): rustc defines the LinkerNotFound diagnostic 'linker `{$linker_path}` not found' with the OS error as a note.
- https://raw.githubusercontent.com/rust-lang/book/main/src/ch01-01-installation.md (official_docs, unknown, official_recommended_action): The Rust Book says Rust needs a linker; if you get linker errors install a C compiler — xcode-select --install on macOS, GCC or Clang on Linux (e.g. build-essential on Ubuntu); Windows gets it via Visual Studio.

Problem details
- Observed symptom
- Compilation succeeds up to link time, then fails with linker `cc` not found (note: No such file or directory).
- Context
- Product: Rust toolchain (rustc/cargo) Component: rustc_codegen_ssa linker invocation Operation: cargo build / cargo install on a minimal image Affected versions: all current rustc versions Environment: Minimal Linux images (debian-slim, ubuntu base, CI containers, WSL), macOS without Xcode CLT Trigger: Rust installed via rustup on a system with no C compiler/linker.

solution · Revision 1
Proposed fix: [Rust/cargo] 'error: linker `cc` not found' on fresh Linux image/container — rustup installs no C linker; install build-essential/gcc/clang
Recommended action: Install a C toolchain: build-essential on Debian/Ubuntu (or distro GCC/Clang), `xcode-select --install` on macOS, Visual Studio build tools on Windows MSVC.
Option: Install a C compiler/linker [evidence: official_recommended_action]
Applies when: Linux/macOS minimal environments
Steps:
1. Debian/Ubuntu: apt-get install -y build-essential
2. Other Linux: install gcc or clang per distro docs
3. macOS: xcode-select --install
4. Re-run cargo build
Expected: Linking succeeds
Evidence basis (self-declared by the contributing chat client): untested.
