[Mingw-users] DLL link problem

[Rosen G. <ros...@ya...>]

I have two problem while linking a DLL file.

1. C object files can't access functions in C++ object
files
	I get error like :

gpu.o(.text+0x239):gpu.c: undefined reference to
`InitDraw'
'InitDraw' is declered in a cpp file

But when i rename all the *.c files to *.cpp so they
compile 
with the C++ syntax this is no longer a problem.
But then i have the next problem :

2. All the export functions declared in the DEF file
give errors
like this one:

gpup.exp(.edata+0x34):fake: undefined reference to
`GPUconfigure'

And in the file i have a function 
long CALLBACK GPUconfigure() { return 0; }

# ========== The makefile looks like (if he could be
the reason)
PROJECT = gpup.dll
DEF_FILE = gpup.def

GCC = gcc
DLLWRAP = dllwrap
CFLAGS = -Ic:\dx7sdk\include -fvtable-thunks -c
-mwindows -O3
LDFLAGS = -Lc:\dx7sdk\lib
LIBS = -ld3dim -ld3drm -ld3dx -ld3dxd -ld3dxof -lddraw
-ldinput \
	-ldplayx -ldsetup -ldsound -ldxguid -lwinmm

CC = $(GCC) $(CFLAGS)

OBJS_CPP = gpu.o gpucmnds.o draw.o

OBJS_C = 
OBJS = $(OBJS_CPP) $(OBJS_C)

$(PROJECT) : $(OBJS)
	$(DLLWRAP) $(LDFLAGS) $(OBJS) --dllname $(PROJECT)
-def $(DEF_FILE)  $(LIBS)

$(OBJS_CPP) : %.o : %.cpp
	$(CC) -o $@ $^
$(OBJS_C) : %.o : %.c
	$(CC) -o $@ $^
#============

Can someone tell me how to get around this?

TNX in advance
