I am experiencing the following error when I attempt to run a Rake task after having added gem 'ffi', '1.10.0' to the Gemfile of a freshly-generated Rails app.

This is with Ruby 2.6.1 and Bundler version 2.0.1 running on macOS 10.14.3.

Output of ruby -v:

ruby 2.6.1p33 (2019-01-30 revision 66950) [x86_64-darwin18]

Output of bundle info ffi:

The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

Here is the output of a sample Rake task eg. rake routes --trace:

This looks like ruby-ffi is linked to a different libffi version at run time than that it was linked to while build time.

Looks like you're right - thanks for the help! Managed to solve with the following:

gem uninstall ffi
brew reinstall libffi
export LDFLAGS="-L/usr/local/opt/libffi/lib"
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
gem install ffi

@larskanis hi, I would be thankful if you could help me. Project uses old version of ffi 1.10.0. I have mac with M1 processor

To install ffi 1.10.0 without error I use option in config file BUNDLE_BUILD__FFI: "--with-ffi_c-dir=/opt/homebrew/opt/libffi"
since homebrew for m1 has new locations for packages. When I run bundle exec foreman start I am getting almost the same as original error : symbol not found in flat namespace '_ffi_type_longdouble'.

I think your answer might be a root cause of my error, but I've tried steps from #687 (comment) and they didn't work. How can I link ruby-ffi to same libffi version at run time and build time?
