[Mingw-users] How to generate the _imp_ prefix?

Let's assume we have the import library and we want to test/link it from VS.
Let's say I have: liblmfit.a, liblmfit.dll.a and lmfit.dll files and I would like my (VS) code/program to link to this import library.
Can you provide some code snippet to demonstrate to concept or process?

How familiar are you with VS?

Thanks for your three mails, Sergio.

   The difficulty is not in building the dependent library under MinGW.
   The difficulty is to link the resulting import library from VS.

   As for my level of experience with MinGW: Zero.

   As for the "plenty of online tutorials", I would be most grateful
   for a link to a really pertinent one.

Back to the problem:

   For a function foo(),
   MinGW generates link symbol _foo (according to dumpbin libmylib.lib)
   whereas VS expects _imp_foo.

Hence the primordial question:

   Shall we tweak MingGW to generate _imp_foo, or VS to expect _foo?
