Building RRFlibraries 'atomic_uint8_t' does not name a type

A Former User

Trying to set up Eclipse to build the firmware and hit a snag that I can't seem to iron out.

I've checked out the following (in git bash, on windows, ~~after giving up on linux~~ linux build works after all, still curious what I messed up here?)

cd /c/eclipse/firmware
git clone https://github.com/dc42/CoreNG.git --branch dev
git clone https://github.com/dc42/CANlib.git
git clone https://github.com/dc42/RRFLibraries.git --branch dev
git clone https://github.com/dc42/FreeRTOS.git
git clone https://github.com/dc42/RepRapFirmware.git --branch v3-dev
git clone https://github.com/dc42/DuetWiFiSocketServer.git

Screenshot to verify (if I've missed something between juggling versions)

It fails with

Am I using the wrong branches of something or the wrong tools? GNU Tools ARM Embedded\8 2018-q4-major

For all targets except SAMC21, type std::atomic_uint8_t should be defined in file <atomic> which is #included at line 24 of RTOSIface.h. On my Windows build system, that file is located in folder C:\Program Files (x86)\GNU Tools ARM Embedded\8 2018-q4-major\arm-none-eabi\include\c++\8.2.1.

Thanks, i found the included file and the include statement doesn't throw an error so a little puzzled as to whats wrong. It does build for Duet2RTOS but not Duet3V06.

No big deal, Kudos to oliof for this thread aiding in getting it built under Debian. Will update thread if I stumble onto the solution for Windows

I build under Windows and I don't have any build problems. Could it be picking up an old include file on your machine?

you sir are a saint and a genius!

I thought I had removed the old stuff from building PanelDue, but I clearly know far too little about eclipse and cross compiling in general.

RRF(libraries) built without issues!
