Building an ARM Cortex-M3 toolchain
From openmulticopter
For programming ARM microcontrollers (including the STM32) you need an ARM toolchain.
Components
- gcc: The GNU GCC ARM compiler
- binutils: The GNU assembler, linker and binary utilities
- newlib: The newlib C library
- gdb: The GNU debugger (optional)
Building the toolchain
You can perform the steps manually of course, but it's probably easier to get the summon-arm-toolchain script. This script supports both, Linux, and Mac OS X.
$ git clone git://github.com/esden/summon-arm-toolchain.git $ cd summon-arm-toolchain
You might want to edit the summon-arm-toolchain script now to match your preferences, then:
$ ./summon-arm-toolchain
This will download and build all required components, and then install the toolchain into $(HOME)/arm-none-eabi (or $(HOME)/arm-elf, depending on your settings). The compile process will require quite a lot of time and disk space.
