Question is like this, has written a serial communication program, now need to add Opencv source code to the used in this project, the results after added directly display various variable is undefined, don't know why, please answer, thank you very much

CodePudding user response:

Is not clear, your definition of a variable, or some of the variables in the opencv,
Case 1: redefining is,
Situation 2: check whether the configuration is correct, and header files and namespace (using the namespace CV, etc.),
