![]() Links to both distribution are given bellow.īefore we move forward with this tutorial first let's understand ARM toolchain naming convention which indicate for WHAT purpose and for WHICH Environment the GCC toolchain was Build! GCC follows UNIX like naming convention which is pretty much loosely followed. Two of the well known are ARM itself (AND who will know ARM Processor better than ARM itself) and Mentor Graphics Sourcery CodeBench. There are many vendors who provide pre-build GCC toolchain binaries for ARM processor. One of the major difference between LLVM and GNU-based toolchains is that of licensing LLVM is distributed under BSD license, while GNU under GPL. ![]() Clang is a viable alternative to the GCC toolchain. Another recently evolved (and evolving with pretty much good phase) toolchain is called Clang Compiler (LLVM project). The beauty of GCC toolchain is that it's absolutely free with support for wide number of target architectures including x86, ARM v4/v5/v6/v7, and many others. This is one of the reason that manually compiling toolchain should be the last option to consider unless you have strong background knowledge of GCC or a target CPU/Processor for which no vendor is supplying GCC toolchain (If you wanna stick to it). Though the process is straight forward, in order to fine tune the toolchain a good background knowledge of GCC is highly desirable. In this article we will learn how to build GCC toolchain for a target processor in general and ARM Cortex-M processor in particular. ![]() A toolchain normally consists of a compiler, a linker, and run-time libraries. A toolchain is a set of tools that compiles source code into executables that can run on your target device.
