Error installing ffi

Question

Can seem to get around this.

$gem install ffi
Building native extensions.  This could take a while...
ERROR:  Error installing ffi:

Any ideas?

I had to set the gcc to 4.2 and it worked. I also changed the ffi version to 1.0.9 in Gemfile.lock.

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

Hi that's related with the GCC compiler i updated mine and also did the trick that Harpreet mentioned (ffi version downgrade) BUT it's not necessary ffi-1.9.3 worked just fine as well :D

in the Gemfile.lock

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