libloader without modifications is able to load only a few libraries.
It doesn't provide complete emulation of Win32, only ~100
implementations of functions that are usually called by audio or video
codecs. These implementations are sometimes very rough ( e.g. if video
codec for some reason tries to discover the position of mouse cursor on the
screen using Win32 function GetCursorPos(), it'll receive fixed numbers ).
New functions are added when it's needed.
Not any library can be loaded ( even theoretically ) with this
loader. If your DLL must communicate with kernel-space driver, you
can give up your project.
You are using loader correctly. I can't say what's going wrong in your
case. Normally, if loader fails because of missing required external
function, it prints 'Called unk_xxxx' just before crash, so you know
what function is missing. It doesn't happen in your case.
Maybe the DLL is not satisfied by some of function implementations.
Try to do this:
extern int LOADER_DEBUG;
( in main() )
LOADER_DEBUG=1;
