问题 Porting a C++ library, under CMake, to Windows. Option 1: Decorate the API with __declspec(dllexport) . Option 2: set(CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS ON) . We go for option 2, since it seems much easier, and leaves our sources intact. Works like a charm: our application compiles and gets linked with the library dll. However, it ensures only the export of classes and functions. What needs to be done to export global variables? Like in: lib_source.cpp: int my_secret; app.cpp: extern int my

问题 I have a module script, in which I import some classes and initialize my app. But module scipts declare var myVar = "my"; in module context, what makes init variables unaccessible to main app code.

问题 I am a young programmer that is learning python and struggling to implement an AI (using minimax) to play TicTacToe. I started watching a tutorial online, but the tutorial was on JavaScript and thus couldn't solve my problem. I also had a look at this question ( Python minimax for tictactoe ), but it did not have any answers and the implementation was considerably different from mine. EDIT: the code you will find below is an edit suggested by one of the answers (@water_ghosts). EDIT #2: I
