Matlab 2011b and mingw64 - matlab

Question

I've followed the guidance I found here.
I have almost completed the work. The following section is the paragraph of batch conversion work. I have created a batch file to convert a lot of DLLs pre-built by MSVC in Matlab 2011b Windows 7(64-bit).
set path=C:\MinGW64\bin;C:\mingw\msys\bin;
mkdir lib
mkdir bin
#echo y |copy *.dll .\bin
#echo y |copy *.lib .\lib
#echo EXPORTS >libmex.def
#echo EXPORTS >libmx.def
#echo EXPORTS >libmat.def
#echo EXPORTS >libeng.def
#echo EXPORTS >libmwlapack.def
c:\mingw64\bin\pexports ./bin/libmex.dll | sed "s/^_//" > libmex.def
c:\mingw64\bin\pexports ./bin/libmat.dll | sed "s/^_//" > libmat.def
c:\mingw64\bin\pexports ./bin/libeng.dll | sed "s/^_//" > libeng.def
c:\mingw64\bin\pexports ./bin/libmwlapack.dll | sed "s/^_//" >libmwlapack.def
gendef ./bin/libmx.dll
echo "Add the mexErrMsgTxt string to each def file,"
echo "then press any key to continue the conversion process"
pause

Makefile for engwindemo.exe:
LIBS= -Lc:/mingw64/lib ../lib/libeng.a ../lib/libmx.a ../lib/
libmex.a ../lib/libmat.a
CC=c:/mingw64/bin/gcc -m64 -O3 -I../include -Ic:/mingw64/include
EXE=../bin/engwindemo.exe
SRC=engwindemo.c
all:$(EXE)
$(EXE): $(SRC)
$(CC) $(SRC) $(LIBS) -L../lib -ladvapi32 -luser32 -lgdi32 -lkernel32 -
lmingwex -o $(EXE)
#rm -f *.o*
Using (mingw64) gcc, the compiling and linking processes is ok. Execute engwindemo.exe, I get this error:
_engClose entry point error (in libeng.dll)
In mingw64, how can I build a stand-alone application (engwindemo.exe) which calls from the functions built-in the libeng.dll (Matlab R2011b)?

Answer 1

Thank everyone response! I have built up successfully! In the Matlab R2011b
win32/64, just setting up in the cygwin(x86_64-w64-mingw32-gcc 4.5.2) environment without any dll file conversion.
The part of primary setting is as following
Set the MATLABROOT in short filename form (long filename may be ok.)
MATLABROOT=c:/Progra~1/MATLAB/R2011b
linking the primary libraries built by MSVC
LIBS= -L$(MATLABROOT)/bin/win64 -lmex -lmx -lmwlapack -lmwblas -leng
declare the gcc with the flags
CC=x86_64-w64-mingw32-gcc
CFLAG=-Wall -m64 -O3 -I$(MATLABROOT)/extern/include
MEXFLAG=-m64 -shared -DMATLAB_MEX_FILE -I$(MATLABROOT)/extern/include -Wl,--export-all-symbols $(LIBS)
Others additional parameters to keep compiler happy.
And finally, in the cygwin consloe or mingw64 shell just make this project.
