What is the difference between arm-linux-gcc and arm-none-linux-gnueabi
Solution 1:
Toolchains have a loose name convention like arch[-vendor][-os]-abi.
-
archis for architecture: arm, mips, x86, i686... -
vendoris tool chain supplier: apple, -
osis for operating system: linux, none (bare metal) -
abiis for application binary interface convention: eabi, gnueabi, gnueabihf
For your question, arm-none-linux-gnueabi and arm-linux-gnueabi is same thing. arm-linux-gcc is actually binary for gcc which produces objects for ARM architecture to be run on Linux with default configuration (abi) provided by toolchain.
Some nice reading: Toolchains.
