Do you have the library system inYour search
CodePudding user response:
For using MinGW dev is no ws2_32. Lib this library file, its corresponding library file is libws2_32. A;Can be added in the project properties linker of the library files, or in the compilation environment - lws2_32 link command to join parameters
