D SDL binding with Derelict2 on Windows

I have problems compiling a D program that uses SDL using a makefile called from DOS, where SDL is supposed to be wrapped by Derelict. In addition, if I use a pragma inside the test program for linking, it tells me the lib file has error 43, not a valid library file.

How to make it link, and am I using the wrong stack (Visual C/C++) ? I think not because it is looking for lib files.

test program

//pragma(lib, "D:\\Development\\SDL-1.2.15\\lib\\x86\\SDL.lib");
import derelict.sdl.sdl;

void main()
{
    DerelictSDL.load();

    // now you can call SDL functions
}

makefile

DMD = dmd
WINDRES = windres.exe
LDFLAGS = -O2 -s `sdl-config --libs`
DFLAGS =
RM   = rm -f
#OBJS = main.o graphic.o grid.o node.o appicon.opc
SRCS = toh_fractal.d
# graphic.d grid.d node.d appicon.opc
PROG = toh_fractal
DERELICT = D:\\Development\\Derelict2
INCLUDE_DERELICT = $(DERELICT)\\import
LIB_DERELICT = DerelictSDL 
LIB_SDL = SDL
#$(DERELICT)\\lib\\
VERS = 0.1.1

.PHONY: clean distclean
all: $(PROG)

$(PROG): $(SRCS)
    $(DMD) $(DFLAGS) $(PROG) -I$(INCLUDE_DERELICT) appicon.res -L$(LIB_DERELICT) -L$(LIB_SDL) 

appicon.res: appicon.rc sierpinski.ico
    windres -i appicon.rc -o appicon.res

distclean:
    $(RM) *~ $(OBJS) appicon.opc stdout.txt stderr.txt

clean:
    $(RM) *~ $(OBJS) $(PROG) appicon.opc stdout.txt stderr.txt

makefile output

Derelict uses the C dl lib (dlopen, dlclose, dlsym) to dynamically load the shared library, so you have to use dynamic libraries.

Derelict is meant ot be used with dynamic linking. You should put the right .so or .dll in your application directory and Derelict will find it.
