Generating .dll files with dllwrap for Visual Studio 2012 (ARPACK)

Question

I am trying to make .lib file of ARPACK library to use with VS2012 Express Edition. Hence I am using the command in MSYS as :

dllwrap --export-all-symbols BLAS/ .o LAPACK/ .o SRC/ .o UTIL/ .o -lgfortran --output-def arpack_win32.def -o arpack_win32.dll

This results in error:

real_write' UTIL/smout.o:smout.f:(.text+0x12cf): undefined reference to _gfortran_transfer_ array_write' UTIL/smout.o:smout.f:(.text+0x12f1): undefined reference to _gfortran_transfer_ integer_write' UTIL/smout.o:smout.f:(.text+0x13b4): undefined reference to _gfortran_transfer_ integer_write' UTIL/smout.o:smout.f:(.text+0x13ef): undefined reference to _gfortran_transfer_ real_write' UTIL/smout.o:smout.f:(.text+0x1581): undefined reference to _gfortran_transfer_ array_write' UTIL/smout.o:smout.f:(.text+0x15a3): undefined reference to _gfortran_transfer_ integer_write' UTIL/smout.o:smout.f:(.text+0x1666): undefined reference to _gfortran_transfer_ integer_write' UTIL/smout.o:smout.f:(.text+0x16a1): undefined reference to _gfortran_transfer_ real_write' UTIL/svout.o:svout.f:(.text+0xb4): undefined reference to _gfortran_transfer_ch aracter_write' UTIL/svout.o:svout.f:(.text+0xd2): undefined reference to _gfortran_transfer_ch aracter_write' UTIL/svout.o:svout.f:(.text+0x1b5): undefined re ference to _gfortran_transfer_i nteger_write' UTIL/svout.o:svout.f:(.text+0x1cd): undefined reference to _gfortran_transfer_i nteger_write'

Cant figure it out why this happens....Thanks..

终于找出了问题所在。...我将MinGW与gfortran一起使用.....在PATH中添加C：\\ MinGW \\ bin解决了所有问题.....
