在OS X中为C / C ++开发人员Mars在Eclipse IDE中设置gcc（gcc-arm-embedded）

Question

I am a newbie in Eclipse IDE for C/C++ . I want to set gcc-arm-embedded in Eclipse IDE for C/C++ Developers Mars Milestone 4 (4.5.0M4), I just downloaded https://launchpad.net/gcc-arm-embedded/+download , and now I guess that I have to set PATH somewhere in Eclipse, as I am experiencing this ERRORs in 1 project

Program "arm-none-eabi-g++" not found in PATH
Program "arm-none-eabi-gcc" not found in PATH

The location of the error is in
Project Properties -> C / C++ General -> Preprocessor Include Paths, Macros, etc -> Languages (GNU C) -> [ CDT GCC Built-in Compiler Settings Cross ARM]

But I can't edit this entry: "Setting entries for this provider are supplied by the system and are not editable"

I've tried with:

export PATH=$PATH:/Users/joanot/Development/gcc-arm-none-eabi-4_9-2014q4/bin

and in

Project Properties -> Paths and Symbols -> adding the directory /Users/joanot/Development/gcc-arm-none-eabi-4_9-2014q4/bin and

Answer 1

In Eclipse -> Preferences -> C / C++ -> Build -> Build Variables:

Create 1 variable named GCC_EABI, type= Directory, value= /usr/local/gcc-arm-none-eabi-4_9-2014q4/bin

In Eclipse -> Preferences -> C / C++ -> Build -> Environment:

Add -> Name = PATH , value = ${GCC_EABI}

Answer 2

In case someone reads this later (like I just did) this works, however the real answer is here

Essentially you need to go to Eclipse -> Preferences -> C/C++ Build -> Tools Paths Add the path (in my case /Users/${USER}/armtools/install/bin) to the Toolchain folder
