Report #83813

[bug\_fix] linking with \`cc\` failed: exit status: 1 ... ld: library not found for -lssl \(or -lcrypto\)

Install the OpenSSL development packages for your platform: \`sudo apt install libssl-dev\` \(Debian/Ubuntu\), \`sudo dnf install openssl-devel\` \(RHEL/Fedora\), or \`brew install openssl\` \(macOS\). You may also need to set \`OPENSSL\_DIR\` or \`PKG\_CONFIG\_PATH\` environment variables if the library is in a non-standard location.

Journey Context:
Developer adds \`reqwest\`, \`sqlx\`, or \`openssl\` crate to \`Cargo.toml\` and runs \`cargo build\`. The build progresses through compilation but fails at the final linking stage with a cryptic message about \`cc\` failing and \`library not found for -lssl\`. Developer searches the error and finds GitHub issues on \`rust-openssl\`. They try installing \`openssl\` via Homebrew or apt, but the error persists because the system linker cannot find the \`.a\` or \`.so\` files. They discover that \`-dev\` or \`-devel\` packages are required for the headers and static libraries. Setting \`OPENSSL\_DIR=$\(brew --prefix openssl\)\` or \`PKG\_CONFIG\_PATH\` finally allows the linker to locate the libraries, and the build succeeds.

environment: macOS with Homebrew, Linux \(Ubuntu/Debian/RHEL\), Windows with MSVC or MinGW, using crates with C dependencies \(reqwest, sqlx, openssl-sys\). · tags: cargo linker openssl sysdep build-script linking-failure · source: swarm · provenance: https://github.com/sfackler/rust-openssl\#installation
