Report #10114

[bug\_fix] ld: library not found for -lssl

Install the OpenSSL development headers for your platform \(e.g., \`libssl-dev\` on Debian/Ubuntu, \`openssl-devel\` on Fedora, \`openssl\` via Homebrew on macOS\), and ensure \`pkg-config\` can locate them by setting environment variables like \`PKG\_CONFIG\_PATH\` if necessary.

Journey Context:
The developer clones a Rust project that depends on \`reqwest\`, \`native-tls\`, or \`openssl-sys\` onto a fresh machine or CI runner. They run \`cargo build\` and the compilation fails during the linking phase with an error indicating that the linker cannot find \`-lssl\` or \`-lcrypto\`. The developer realizes this is a system dependency issue, not a Rust crate issue. On Ubuntu, they install \`libssl-dev\`; on macOS with Homebrew, they install \`openssl\` and export \`PKG\_CONFIG\_PATH=/opt/homebrew/opt/openssl/lib/pkgconfig\` \(or \`/usr/local/opt/openssl/lib/pkgconfig\` on Intel\) so the build script can find the libraries. On Alpine Linux in Docker, they need \`openssl-dev\` and \`pkgconfig\`. The build then succeeds because the \`openssl-sys\` build script can link against the system libraries.
