Compile Error in Arduino 1.8.19.

Added #include to line 9 to correct.

  1. Which version of Teensyduino?
  2. If not a Teensy, which platform and version?
  3. Which version of the library?

I did a complete removal and re-install of Arduino 1.8.19 and Teensyduino 1.57 and this issue seems to be resolved.

Have you tried Teensyduino 1.59? I recommend that instead.

ssilverman commented 7 months ago

I just added the missing <cstdlib> include to sys_arch.cpp. It’ll appear when I push next. (Note that it seems to work fine without the include, in Teensyduino 1.59 but not in 1.57.)
