How Do I debug LNK2001 errors?

[charris67]

I keep getting the the 2 fatal errors

"error LNK2001: unresolved external symbol ___WSAFDIsSet@8"
"error LNK2001: unresolved external symbol __select@20"

when I build the project. How do I debug link error since unlike syntax errors, double clicking a link error won't take you to the relevant code line.

Thanks.

Look in the documentation for the WSAFDIsSet function. It should specify a header file to include and a lib file to link with. Add that lib file to your project settings.

Search for WSAFDIsSet and detemine which library is needed for it .. and include those in the project.

Same with select@20
