Compiling FluidSynth 1.1.1 from source. I have unresolved external symbol with glib, using Visual C++ Express 2010, how do I actually link the glib.lib correctly in the IDE? Do I need wsock libraries as well?

So when we try to assign it a value in the main function, the linker doesn't find the symbol and may result in an “unresolved external symbol” or “undefined reference”. The way to fix this error is to explicitly scope the variable using '::' outside the main before using it.
Answer. Unresolved external references occur when the symbol for a function or global variable is referenced in a program, but none of the object files or libraries specified in the link step contain a definition for that symbol.
Since you have already resolved most of your problems, and are just missing the winsock stuff.
You need to install the Windows Platform SDK, which will install a lot of libraries. In the install location's lib directory will be the file ws2_32.lib, which is the Winsock2 library you want to link against.
