Hey @chrishough 👋 This is not a problem with GCC, these are just warnings. The problem is that the wrong platform is picked up which is a known issue with bundler (should be fixed though).

• How are you trying to install mini_racer? If you are using Bundler, can you make sure that you have specified the correct platform in Gemfile.lock via bundle lock --add-platform?
• Can you make sure to have the latest Bundler installed? Should be 2.3.6

You are trying to install libv8-node-16.10.0.0-x86_64-linux-musl for musl libc which doesn’t seem to be the right target.

PS: libv8 is no longer used with mini_racer.
