Is Cygwin a cross-compiler?

The Cygwin Ports repository contains cross-compilers for i686, x86_64, armv7hl, and aarch64 GNU/Linux targets.

Can GCC cross compile?

You could do your builds on different physical or virtual machines, but that means maintaining several systems. Instead, you can use the GNU Compiler Collection (GCC) to cross-compile, producing binaries for several different architectures from a single build machine.

How do you set up a cross-compiler?

Cross compilation will happen on a Linux x86 machine for 96Boards ARM device.

1. Step 1: Update 96Boards (ARM) system and Host (x86 Machine) computer.
2. Step 2: If you are using libsoc and or mraa make sure they are installed and up to date.
3. Step 3: Install cross compilers on host machine.
4. Step 4: Install package dependencies.

How do I cross compile GCC for arms?

2 Answers. Install gcc-arm-linux-gnueabi and binutils-arm-linux-gnueabi packages, and then just use arm-linux-gnueabi-gcc instead of gcc for compilation. This brings in the complete cross-compile environment, including binutils. On Ubuntu 13.10 you get gcc-4.7 for ‘gnueabi’ and gcc-4.8 for ‘gnueabihf’.

What is cross compiling GCC?

The GCC cross-compiler works just like your local version: It just creates a different type of executable for an alternate platform. This means that you can use the same command-line options, such as header and library locations, optimization, and debugging.

Is there a new binutils compiler for GCC?

We’re not going to build a new Binutils, which GCC relies on, because the existing Binutils provided by Cygwin is already quite recent. We’re also skipping a couple of packages, namely ISL and CLooG, which means that the new compiler won’t be able to use any of the Graphite loop optimizations .
