Report #70814

[bug\_fix] linker \`cc\` not found

Install a C compiler and linker toolchain: on Debian/Ubuntu \`sudo apt install build-essential\`, on Fedora \`sudo dnf install gcc\`, on macOS install Xcode Command Line Tools.

Journey Context:
Developer installs Rust via rustup on a fresh Linux WSL or VM. They run \`cargo build\` on a new project and immediately get an error that the linker \`cc\` was not found. The error occurs because Rust requires a system C linker \(\`cc\`, \`gcc\`, or \`clang\`\) to link object files, even for pure Rust projects \(for stdlib\). The developer searches the error message, finds GitHub issues explaining that \`build-essential\` \(Debian\) or \`base-devel\` \(Arch\) is required, installs it, and the project links successfully.

environment: Fresh Linux \(Ubuntu/Debian/Fedora/Arch\), WSL, minimal containers · tags: cargo linker build-dependency system-requirements · source: swarm · provenance: https://www.rust-lang.org/tools/install
