This is a Windows Console application (actually a service) that a previous guy built 4 years ago and is installed and running. I now need to make some changes but can't even build the current version! Here is the build output:
--------------------Configuration: MyApp - Win32 Debug--------------------
Compiling resources...

LINK : warning LNK4098: defaultlib "LIBCMTD" conflicts with use of other libs; use /NODEFAULTLIB:library

Debug/MyApp.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
MyApp.exe - 2 error(s), 1 warning(s)
--------------------------------------------------------------------------
If I use /NODEFAULTLIB then I get loads of errors. The code does not actually use _socket_noblock but I can't find anything on it on the 'net. Presumably it is used by some library I am linking to but I don't know what library it is in.

Sorry, this turns out to be an internal problem. A combination of a maverick coder 4 years ago and a rusty no-nothing (me!) now.
The code does not use _socket_noblock but it does use socket_noblock and I just need to link to one of our own libraries.
