How to compile unmanaged *.dll with makefile on windows

[Freefall63]

Hey guys,

 

I want to compile the adplug C/C++ source into a unmanaged *.dll to use it in .NET with PInvoke,

but I don´t get the makefile compiling to work. Could anybody please tell me how to compile that package?

 

Thanks for your effort!
