title: MinGW linker error: winsock
body: <p>I am using MinGW compiler on Windows to compile my C++ application with sockets. My command for linking looks like:</p>
  
  <pre><code>g++.exe -Wall -Wno-long-long -pedantic -lwsock32 -o dist/Windows/piskvorky { there are a lot of object files }
  </code></pre>
  
  <p>and I have also tried </p>
  
  <pre><code>g++.exe -Wall -Wno-long-long -pedantic -lws2_32 -o dist/Windows/piskvorky { there are a lot of object files }
  </code></pre>
  
  <p>but in both case I get this error:</p>

  <p>Do you have any ideas where the problem can be, please?</p>
