Demo's always give compile errors

[g7kse]

Unfortunately all efforts to compile any of the examples results in similar compile errors. An example from the demo is....

Error compiling for board ESP32 Dev Module.

Similar 'exit status 1' errors appear on all all examples but other simpler wifi scan esp32 examples do work.

I've used the dev board branch, used different machines, reinstalled arduino ide etc don't know where to go next....any clues?

Using this work around does solve it but this shouldn't really be normal should it?
