Installing `libssl`

TruffleRuby provides the openssl gem but not the native libssl system library that the gem uses. TruffleRuby supports libssl versions 1.0.2, 1.1.0 and 3.0.0.

If you experience openssl-related errors, it might help to recompile the openssl gem by running lib/truffle/post_install_hook.sh. This is done automatically by Ruby managers.

To compile TruffleRuby against a non-system libssl, set OPENSSL_PREFIX while installing TruffleRuby:

export OPENSSL_PREFIX=/path/to/my/openssl-1.1.0

Fedora-based: RHEL, Oracle Linux, etc

sudo dnf install openssl-devel

Debian-based: Ubuntu, etc

sudo apt-get install libssl-dev

macOS

On macOS the system version is too old.

Homebrew

We recommend installing libssl via Homebrew.

brew install openssl

MacPorts

MacPorts should also work but is not actively tested.
