I was able to get Ruby 2.5.1 building on M1 by following two of the steps in that GH issue...
rbenv/ruby-build#1691 (comment) rbenv/ruby-build#1691 (comment)
I installed readline and openssl with standard brew install.
brew install readline
brew install opensslThen I set this in my ~/.zshrc..
# Homebrew
export PATH=/opt/homebrew/bin:$PATH
export PATH="/opt/homebrew/sbin:$PATH"
# rbenv
export RBENV_ROOT=/opt/homebrew/opt/rbenv
export PATH=$RBENV_ROOT/bin:$PATH
eval "$(rbenv init -)"
# openssl
export PATH="/opt/homebrew/opt/[email protected]/bin:$PATH"
export LDFLAGS="-L/opt/homebrew/opt/[email protected]/lib"
export CPPFLAGS="-I/opt/homebrew/opt/[email protected]/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/[email protected]/lib/pkgconfig"
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=/opt/homebrew/opt/[email protected]"
Then I ran this command:
RUBY_CFLAGS="-Wno-error=implicit-function-declaration" rbenv install 2.5
I haven't been able to test this yet, but @samik3k has reported that this no longer works, but that the following command does.
RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.8
Please reply and let me know if this works for you and I'll update the steps above as I don't have Ruby setup on my M1 Mac right now.
RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.0This worked on MacOS 14.2 M2. Thank you!
