whenever seek building code server next errors:

i'm totally new. i'm using code blocks. i've been searching solution lastly 4 days i'm not understanding anything. please help

if using codeblocks, utilize mingw goes (i guess, according low experience level).

this feature works @ visual studio compilers:

#pragma comment(lib,"ws2_32.lib")

with mingw such #pragma not work.

instead if have open "project" -> "options", take project @ left tree (or "debug"/"release", if want alter work there), , open tab "link settings".

press "add" , find library name "libws2_32.a" in mingw/lib/ directory.

after seek rebuild. hope helps.
