[Dev-C++] Using DLL created with Dev-Cpp

[Dmitry S. <si...@si...>]

Hello,

I created some DLL using Dev-Cpp
Now I need to use it implicitly in some VisualC++ project
I added a header file to this project, specify a path to .a file to
linker and put dll in the output directory
Bu I cannot link it :(
I get LNK2001 unresolved symbol errors
On the other hand I could use this dll implicitly in projects written
in Dev-Cpp

Maybe some format error? Does anybody know?

Dmitry

The problem is with the .a file. Visual C++ uses a .lib file which has a 
different format than the .a file used in Mingw/Dev-C++.

Essentially you need to find a utility to preform this conversion. I 
know implib (or something similar) will do the conversion the other way 
around but I do not know of a utility to do from .a to .lib.

You could also try compiling the DLL under Visual C++ and let it produce 
it's own .lib from which you can get a .a for use with Dev-C++. Sadly 
this is not something I have ever done in Visual C++ so you are on your 
own there.
