i am trying to send data from my tx pin to my rx pin, i cant see any problem with this program however it fails to run.
this is my error message

The compiler isn't outputting a reason for the failure. Is this a feature you have somehow disabled? I would also suggest deleting all intermediate files and doing a full rebuild.
