Getting ruby-libgd installed

As per usual native extensions don’t always install 1st time. Damn…

Installing ruby-libgd 0.1.9 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

The error is right there.

gem install ruby-libgd
Building native extensions. This could take a while...
ERROR:  Error installing ruby-libgd:
	ERROR: Failed to build gem native extension.

    current directory: /Users/rl/.asdf/installs/ruby/3.4.6/lib/ruby/gems/3.4.0/gems/ruby-libgd-0.1.9/ext/gd

libgd not found

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /Users/rl/.asdf/installs/ruby/3.4.6/lib/ruby/gems/3.4.0/extensions/arm64-darwin-24/3.4.0/ruby-libgd-0.1.9/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /Users/rl/.asdf/installs/ruby/3.4.6/lib/ruby/gems/3.4.0/gems/ruby-libgd-0.1.9 for inspection.

Looks like libgd is already installed.

brew install libgd

You have 125 outdated formulae and 2 outdated casks installed.

Warning: gd 2.3.3_6 is already installed and up-to-date.
To reinstall 2.3.3_6, run:
  brew reinstall gd

So I need to include the path the native libraries when installing.

gem install ruby-libgd -- --with-gd-include=/opt/homebrew/include --with-gd-lib=/opt/homebrew/lib
