发帖数: 165 | 1 where to create the macro in compiler configuration, so when compile, it
will only compile part of the code that is defined by the macro? something
like
\D Load_FILE
thanks. |

发帖数: 1759 | 2 i think you are looking for preprocessor definitions.
in your source code:
#ifdef Load_FILE
cout << "Load_FILE is defined";
#else
cout << "Load_FILE is not defined";
#endif
in your compiler settings, add:
-DLoad_FILE
without space between -D and your preprocessor definition. |

properties -> c/c++ -> preprocessor -> preprocessor definitions
