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 Unfo         


        

Answer 1

Also method:

export SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
bundle update

ffi.h is to be found in ${SDKROOT}/usr/include/ffi/ffi.h.
