Re: Ada on iOS ? Or Swift...

Ok, I hit the same problem I had building a cross compiler on Linux for macosx (I have the mac fs mounted using nfs, btw). I downloaded the prebuilt gcc-4.9.1 for yosemite that was posted recently and installed that in my PATH.

The above build was for building for the iPhoneSimulator.

I've no idea how to get past this.
