Linking a native msvc dll library to CYGWIN g++ compiler

[Mümin A.]

Hi,

I'm facing a problem while linking my native dll library into the g++
compiler.

There is a name mangling problem when calling a msvc function from g++
compiler therefore linker gives an error undefined reference.

Is there any method to directly link and call a function from native dll
library from the cygwin compiler ?



For example, I've a fooCls.h header file for a windows library,  I add link
the fooCls.dll to g++ compiler then,

fooNameSpace::fooConnectionCls instance;
instance.FooTest();

gives a linker error , undefined reference.


Thank you in advance,
