Question

I'm attempting to do a bundle update on my rails application but I get the following error:

Installing ffi (1.0.11) with native extensions Unfortunately, a fatal error has occurred. Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler/issues so that we can fix it. Thanks!

Any ideas?

Answer 1

Ubuntu Trusty LTS 14.04

Needed to switch from ruby 2.2.1 to 2.3.0 to support newer gem versions in Rails app.

Solution:

1. rvm get stable
2. rvm remove 2.3.0
3. rvm install 2.3.0
4. bundle install

Answer 2

I had to accept the Xcode User licence:

Running sudo xcrun cc should bring up the cli version of the Xcode license agreement. Another option is to open Xcode.app and agree in the GUI.

Possibly caused by updating OSX.

Answer 3

For Xcode 5 and later:

$ xcode-select --install

to install the Command Line Tools.

Answer 4

For me I just didn't have gcc installed, solve in Ubuntu by:

sudo apt install build-essential

Answer 5

Mac OSx 10.10.2 yosemite

 CC=/usr/bin/i686-apple-darwin11-llvm-gcc-4.2 gem install ffi

and thats it -check that you have 4.2 compiler in /usr/bin that you can hook into

ls /usr/bin|grep gcc|grep 4.2

You do not have to wipe out all of your local gems or override symlinks to do this - its a waste of time and will likely create more problems then it solves.

please note, your bin path may be different if you needed to install via brew

brew install apple-gcc42
