libaws is a C++ library that allows to communicate with Amazon Web Services. Currently supported are Amazon S3, SQS, and SDB.
There was a time when I was desperately looking for a more C++ friendly S3 library; thats when I came across this one. I thought I had struck gold; it was golden indeed. But beneath the crust, it was some other crude metal which I couldn't make head or tail of! Point is, if you are looking for some back-to-front API in the name of C++, this if for you! You probably are much better off wrapping a curl based C library called libs3 beneath a C++ interface! I have used this approach in several projects and it works well!
Well done !
