[ruby-talk:444556] Can't gem install websocket-driver on Ubuntu 22.04

Hi all,

I am new to Ruby and just trying to get started with Rails; however I am
having some difficulty getting things installed on my Ubuntu 22.04 machine.
I installed build-essential and then installed rvm, and using rvm installed
ruby-3.3.5. But when I tried to `gem install rails` things broke, and it
seems to be isolated to the websocket-driver. I asked over on Github
<Issues · faye/websocket-driver-ruby · GitHub; about but he
suggested I ask on this mailing list instead. Here's the full output of
what I see when I try and install it:

$ gem install websocket-driver

Gem files will remain installed in
/home/gmyers/.rvm/gems/ruby-3.3.5/gems/websocket-driver-0.7.6 for
inspection.

As far as I know, I have the latest gcc (it's version 11.4.0). Has anyone
else encountered issues like this before? Any advice?

I see you already fixed your issue by installing clang and using that to build the gem.

When you installed ruby with rvm did you build from source or install a binary? "By default RVM will try to download binary ruby package instead of compiling. If such package is not available normal compilation will be performed."

I don't know which compiler they use for the prebuilt binary. Something like this may shed some light:

ruby -rrbconfig -e 'puts RbConfig::CONFIG["CC"]'
