osx - What is CPU structure of my MacBook Air? -

i wanted install latest gcc on macbook air, got error ld: warning: ignoring file /usr/local/lib/libmpfr.dylib, file built i386 not architecture beingness linked (x86_64)

x86_64 shown uname -m i386 uname -p. heck cpu sturcture of mba, bought not more 1 year?? model type a1466 emc 2632.

it's core i5 or core i7 (architecture x86_64).

but reply programming question, .dylib has not been built 64-bit. rebuild universal , work both 32- , 64-bit.

edit don't waste precious time installing gcc source takes ages , means getting dependencies right (something you've failed here). instead install macports , type:

$ sudo port install gcc49

and configure you.

osx macbook
