C++ language bindings for ev3dev

Compiling

• EV3:

mkdir build
cd build
cmake .. -DEV3DEV_PLATFORM=EV3
make

• BrickPi:

mkdir build
cd build
cmake .. -DEV3DEV_PLATFORM=RPI
make

You have several options for compiling.

Cross-compiling

You can use a cross-compiling toolchain to create ARM compatible code. Note: You need a Linux toolchain, not a "bare-metal" toolchain. If it does not have "linux" in the name, it probably won't work.

Pros: Fastest option. Works on Windows and Mac without a virtual machine.

Cons: Only includes standard libraries - no Debian -dev packages.

Windows

MentorGraphics toolchain (formerly known as CodeSourcery).

Mac

Carlson-Minot toolchain

Brickstrap

Brickstrap uses QEMU to create a virtual environment (not exactly a virtual machine) that can run the same ARM compatible code on a different type of computer.

Pros: Faster than running on the EV3 itself. Can install all Debian -dev packages using apt-get.

Cons: Slower than cross-compiler. Requires Linux (Ubuntu).

See this page for instructions.

On the Brick

It is possible to compile programs on the EV3 brick itself.

Pros: Easy to setup.

Cons: Really slow.

Just run sudo apt-get install build-essential on the EV3 and you will have everything you need.
