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, and mentioned in the post-install message when installing TruffleRuby via gu install in GraalVM.
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.
sudo port install openssl
