How can I fix "ws2_32.h" not found error?

Question

I am trying to write a simple socket code in codelite on windows but I can not import ws2_32.h so my project is not working and I am getting "No such file or directory".How can i fix this problem.I tried to write this in the linker options but I could not be successful.I researched the problems like this but I could not understand.This is a new version of Codelite and different from others.I am using MinGW as compiler.

Edit: I removed the library which one unnecessary and wrong(#include "ws2_32.h") and when I add "-Iws2_32" to the linker options problem solved.

The ws2_32 library is indeed necessary for socket functionality on Windows.

So you must link with the -lws2_32 flag.

But the include line should be #include <winsock2.h>, and - depending on which functions you call - possibly others like #include <ws2tcpip.h>.

Note that as these libraries are considered system include files on Windows you should use angle brackets (<>) instead of double quotes ("").
