How to build rrf v2-dev branch in 2020?

[PieTorque]

Hello,

I've been trying to build the v2-dev for quite some time now. I've tried plenty of different commit combinations but there's always errors. I did manage to build the master branches without an issue so I must've gotten something right.

Usually the problems are tied to some method or header file missing or not found.

The recent errors that occured are as follows:

../src/Storage/MassStorage.cpp:393:8: error: 'const class StringRef' has no member named 'Truncate'

src/Storage/subdir.mk:27: recipe for target 'src/Storage/MassStorage.o' failed
make: *** [src/Storage/MassStorage.o] Error 1

Does anybody know if it's something with the compatibleness of branches, or do I need to get some things right in the ArmGccPath or somewhere else in compilation settings?

Also in the https://github.com/Duet3D/RepRapFirmware/blob/v2-dev/BuildInstructions.md it tells you to make sure there's a copy of make.exe in your path, does this mean it should be in the eclipse ide build variables? Or in system enviroment variables?

Thank you for your answers beforehand!
