Running ARM program on xcode

gccxcode

I'd like to have a compiler for ARM on my Mac, and I read somewhere that there is a way to run and maybe debug ARM code on Xcode.
Anyone has any hint on how I should do or if it is even possible?
Any other solution for ARM on Mac?
Thanks

Running ARM code on macOS

See How to emulate an ARM architecture under OSX 10.6 (“Snow Leopard”)? The answers to this question include suggestions for:

QEMU

QEMU is a generic and open source machine emulator and virtualizer.

QEMU can be installed from Homebrew: brew install qemu

Skyeye

Skyeye is a multi-architecture, multi-core, and highly scalable hardware simulation platform. Cur- rently it is implemented by the core library libcommon.so and a series of plug-ins based on the composition of the core library. SkyEye supports the system structure of ARM, Blackfin, Coldfire, PowerPC, MIPS, SPARC and x86.

Skyeye may be no longer under active development.

Cross Compiling ARM with Xcode

Getting Xcode to correctly cross-compile non-iOS device ARM code on the Mac appears to be possible, if tricky. You may find focusing on command line compiling easier.

embedXcode

embedXcode is a template for Xcode, Apple's official IDE on Mac, and eases development for the most popular embedded computing boards.

How to specify what is used as the real C compiler

Apple's gcc binary is really llvm.

Mac:~ bmike$ which gcc
/usr/bin/gcc
Mac:~ bmike$ gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

You'll want to obtain gcc from homebrew or from source if you need gcc and not llvm standing in for gcc.

Good reading abounds on various blogs:

Once you've gotten a real version of gcc installed, you can export CC=/usr/local/bin/gcc or whatever else you prefer for setting the environment variable to match were you choose to store your now non-llvm-based compiler.

Mac – Update Xcode from 4.6.1 to 4.6.3 for Homebrew

I have just found this on GitHub Gists.

Try enter the following command in Terminal:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

Solved my brew doctor problem of Homebrew not recognising updated version of Xcode.

Also see this Homebrew compatibility guide and ensure that your OS is compatible with Command Line Tools on their own or if you need the full version of Xcode.
