{"answer":"Recommended action: Install pkg-config and libssl-dev (Debian/Ubuntu) or openssl-devel (Fedora); or set OPENSSL_DIR; or enable the `vendored` feature (needs C compiler, perl, make) to build OpenSSL statically; for cross builds consider switching to a rustls-based TLS feature if the dependent crate offers one.\n\nOption: Install OpenSSL dev headers and pkg-config [evidence: official_recommended_action]\nApplies when: Linux native builds\nSteps:\n1. apt-get install -y pkg-config libssl-dev (or dnf install openssl-devel pkgconf)\n2. cargo clean -p openssl-sys && cargo build\nExpected: Build script finds OpenSSL\n\nOption: Use the vendored feature [evidence: official_recommended_action]\nApplies when: Cross-compiling or no system OpenSSL\nSteps:\n1. Add openssl = { version = \"0.10\", features = [\"vendored\"] }\n2.
