B4R Question (Solved) Error msg

[derez]

Compiling with arduino nano the blink program or any other I get this error:

new.cpp.o (symbol from plugin): In function `operator new(unsigned int)':
(.text+0x0): multiple definition of `operator new(unsigned int, void*)'
D:\B4R\Blink\Objects\bin\sketch\B4RCore.cpp.o (symbol from plugin).text+0x0): first defined here
collect2.exe: error: ld returned 1 exit status
exit status 1

In arduino IDE it works, I installed B4R again but no change.

Solved: I updated the nano board in arduino IDE and downgraded avr to ver 1.8.1
