I have used

dllwrap --export-all mdll.dll = mylib.a -L.=20 -lgmp

I get the DLL file.

But when I try to use it in a Visual = C++=20 application it gives me a undefined reference to the = function

names defined in this = DLL.

I created a export .DEF file which = is as=20 follows

LIBRARY <dllname>

EXPORTS

= function1

= function2

etc..

Then I created a import file = ..lib=20 using

dllwrap --dllname <name.dll> = --output-lib=20 <libname.lib>

This created a .lib = file

This when linked into a Visual C++ = application=20 it compiles and links properly but when

I try to run this application it = just terminates=20 at the function call.

Can anybody help me.
