ruby-install fails when installing ruby 2.6.x and 3.0.x on mac osx 11.6-CodePudding

When running ruby-install, it fails to build. This also reported in rbenv issues (https://github.com/rbenv/ruby-build/issues/1725).

for example when installing ruby 2.6.8

# installing via ruby-install ( https://github.com/postmodern/ruby-install )
ruby-install ruby 2.6.8

it results in the following error

ossl_x509store.c:452:30: note: ')' token is here
    result = rb_funcall(ctx, rb_intern("verify"), 0);

seems to be complier issue. first ensure that xcode is installed appropriately. In my case, I had it installed prior but you can opt to reinstall to be sure. hope this helps people save time trying to figure out the issue as compiling it takes several minutes.

# check xcode, should yield : /Library/Developer/CommandLineTools
xcode-select -p

# check xcode, should yield : xcode-select version 2384
xcode-select -v

# install xcode-select
xcode-select --install

# reinstall openssl and version 3
brew reinstall openssl@1.1
brew install openssl

# install build dependancies
brew install openssl readline libyaml zlib llvm bison

# ensure build is using LLVM compiler
export PATH="/usr/local/opt/llvm/bin:$PATH"
export CPPFLAGS="-I/usr/local/opt/llvm/include"

# ensure build is using bison
export PATH="/usr/local/opt/bison/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/bison/lib"

# set ruby compilation flags

export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl) --with-readline-dir=$(brew --prefix readline) --with-libyaml-dir=$(brew --prefix libyaml) --with-zlib-dir=$(brew --prefix zlib)"

# install ruby via ruby-install
ruby-install ruby 2.6.8

I can not install any rubies by compiling on Big Sur. I get this:

I had the same issue when I ran the following command: ruby-install ruby 2.6.8 -- --with-openssl-dir=$(brew --prefix [email protected]).

I updated bison with brew install [email protected] and ran export PATH="$(brew --prefix [email protected])/bin:$PATH" to fix ripper. Then, re-running the initial ruby command worked!
