What is a DLL.a file and how do I load one into my VC++ project

I have recently stumbled upon an open source project that I would like to take part in, but I've noticed that they have DLL.a files. I've never seen this file type before and as a programmer for a decent 5 years I've learned not to assume so开发者_如何学Cmething that I don't understand.

Any advice would be greatly appreciated.

These are archive files, which are static libraries intended for use on a Linux system. They won't work with Visual Studio, you'll need to find the Windows libraries (if they exist).
