after searching and trying to solv emy Problem I now ask You Guys. Since Today I cant compile simple Code no matter self written or from the Examples on any Arduino Board. When I use the NodeMCU Board everythin works fine.
Here is my Error:
"/usr/bin/avr-gcc-ar" rcs "/tmp/arduino_build_636407/core/core.a" "/tmp/arduino_build_636407/core/wiring_pulse.S.o" signal: segmentation fault (core dumped) Error compiling for board Arduino/Genuino Uno.
