Hello @clayborg,

The same thing on my Linux machine:

  1: test_with_dwarf_and_run_command (TestDataFormatterSynthVal.DataFormatterSynthValueTestCase)
     Test using Python synthetic children provider to provide a value. ... (myInt) x = 3
  (myInt) x = 3
  error: call to a function 'myInt::myInt(int)' ('_ZN5myIntC1Ei') that is not present in the target
  error: The expression could not be prepared to run in the target
  FAILURE
