Error installing ffi

It might seem to get around this.

$gem install ffi Building native extensions. This could take a while... ERROR: Error installing ffi: ERROR: Failed to build gem native extension. /remote/part/usern/.rvm/rubies/ruby-1.9.3-p448/bin/ruby extconf.rb checking for ffi.h... no checking for ffi.h in /usr/local/include,/usr/include/ffi... no checking for rb_thread_blocking_region()... yes checking for rb_thread_call_with_gvl()... yes checking for rb_thread_call_without_gvl()... yes checking for ffi_prep_cif_var()... no creating extconf.h creating Makefile make libffi.gnu.mk:16: Extraneous text after `else' directive libffi.gnu.mk:18: *** only one `else' per conditional.

Any ideas?

I needed to install gcc on 4.2 and it worked. I also changed ffi version to 1.0.9 in Gemfile.lock.

export PATH = / opt / gcc-4.2.0 / bin /: $ PATH

Hi related to the GCC compiler, I updated my version and also did the trick Harpreet talked about (version for ffi version), but this is not necessary. ffi-1.9.3 worked fine too: D

in the Gemfile.lock file

  ffi (1.9.3) ffi (1.9.3-x86-mingw32)
