Here is a part of compiled output :

Seems sort of obvious if you read the error messages. One of your project's header files (probably DeviceControl.h) is pulling in an incorrect header file. Looks like it is pulling in <limits> when it should be pulling in a header where min() and max() are defined as macros.
