Compiler toolchains naming convention
Unix cross compiler naming conventions can seem mystifying. If you search for an ARM compiler, you might stumble across the following toolchains: arm-none-linux-gnueabi, arm-none-eabi, arm-eabi, and arm-softfloat-linux-gnu, among others. This might leave you wondering about the method to the naming madness. Toolchains have a loose name convention like arch[-vendor][-os]-abi . arch is for architecture: arm , mips , x86 , i686 ... The arch refers to the target architecture, ex: ARM. vendor is tool chain supplier: apple , The vendor nominally refers to the toolchain supplier. os is for operating system: linux , none (bare metal) The os refers to the target operating system, if any, and is used to decide which libraries (e.g. newlib, glibc, crt0, etc.) to link and which syscall conventions to employ. abi is for application binary interface convention: eabi , gnueabi , gnueabihf The abi ...
