gem install nio4r -v '2.3.1' fails #195

Closed AndrewRayCode closed 5 years ago

AndrewRayCode commented 5 years ago

This is possibly related to https://github.com/thoughtbot/capybara-webkit/issues/1071. I'm on OSX 10.13.6 and using XCode 10. The second cstddef error is also in the linked ticket.

Error 1

Fix attempt #1:

$ xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

It's not very effective

Fix attempt #2:

$ brew install cgal

This is a problem with your local environment:

In file included from ./../libev/ev.c:1591:
In file included from /usr/local/include/float.h:29:

For whatever reason /usr/local/include has higher precedence than the system include directories, and it's pulling in /usr/local/include/float.h instead of the one from your C standard library.

For any archaeologists, this error occurred on a new computer (mac) that I had done a hard drive transfer to. There were lots of old homebrew-y files and probably other things left lying around, and since the operating system version had changed, things were in a weird state.

My solution was to first fully uninstall homebrew, then rm -rf /usr/local, and reinstall things with homebrew as I needed them
