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

@user-m_123 please check the documentation https://github.com/Duet3D/RepRapFirmware/wiki/Building-RepRapFirmware

Your problems are that the GNU Arm tools and the make are not installed and/or not in the path to be found. arm-none... are the GNU ARM toolchain 8 2018 q4, the make is a special version to handle long command lines. After installing and adding to path, Eclipse must be restarted to be effective.

[user M_123]

@joergs5 it's installed

@user-m_123 if you open a command line with calling cmd and say arm-none-eabi-g++, does it find the program? The same with make?

[user M_123]

[JoergS5]

@user-m_123 it must be also in the path. And the version is newer than the version 8 2018 q4 which I'm using. I don't know whether 10 2020 q4 is compatible.

[user M_123]

@joergs5 yes it is

@user-m_123 did you check calling the program from commandline?
eg

C:\Users\Joerg>arm-none-eabi-g++ --version

@user-m_123 are you building under Windows or under Linux?

[user M_123]

[user M_123]

@joergs5 Thanks for your support it is build perfectly

[JoergS5]

@user-m_123 that's fine, don't hesitate to ask when there is a new question.

@user-m_123 from https://github.com/Duet3D/RepRapFirmware/wiki/Building-RepRapFirmware:

The build depends on the Eclipse workspace variable ArmGccPath being set to the directory where your arm-none-eabi-g++ compiler resides. For example C:\Program Files (x86)\GNU Tools ARM Embedded\7 2018-q2-update\bin on Windows (see step #1 for which compiler to use). To set it, go to Windows -> Preferences -> C/C++ -> Build -> Build Variables and click "Add..."

It sounds to me that you didn't do that step. The Eclipse project is set up so that Eclipse uses that variable to find the compiler.
