Heres a better version that automatically generates a class wrapping the portaudio.dll. Need portaudio.di(possibly renamed to portaudio.d and imported). Still same problem as original though. import portaudio; import std.conv, std.stdio; import core.stdc.stdio; alias BOOL = ubyte; alias

Well, it happened to me once [1], and the reason is that templated functions are final by default (since, as you said, it doesn't make sense for them to be anything else). This way the body of the function is assumed to be in a different compilation unit (which is not, hence the linker

A DLL Loader prototype that loads DLL's, just specify the declaration. Probably should be worked up so it is easy to load DLL's. Example: import portaudio; import std.conv, std.stdio; import core.stdc.stdio; //pragma(lib, "portaudio_x86.lib"); // Doesn't work because libs are invalid
