Cross Compilation¶

Raspberry Pi¶

These cross compilation steps are meant to be used for an Ubuntu Linux stystem.

Toolchain¶

In order to create the toolchain for the raspberry pi environment the easiest way to go is by using the crosstool-ng utility meant to support the creation of the toolchains for embedded devices.

A series of commands exist to control the creation of the toolchain but the most important ones are the following.

ct-ng menuconfig
ct-ng build

The configuration for the raspberry toolchain is the following.

Crosstool-NG version: 1.20.0
CPU Architecture: ARM
Operative System: Linux
Toolchain Path: /opt/${CT_TARGET}
Tuple's vendor string: rasp
Compilers: gcc and g++
