I've borrowed a load of code from the AWS SDK CPP guide and boiled it down to this:
const Aws::String& 
objectName = "file.txt";
Aws::Client::ClientConfiguration clientConfig;
clientConfig.scheme = Aws::Http::Scheme::HTTPS;
clientConfig.connectTimeoutMs = 30000;
clientConfig.requestTimeoutMs = 600000;
Aws::S3::S3Client s3_client(clientConfig);
Aws::S3::Model::PutObjectRequest putObjectRequest;

std::shared_ptr<aws::iostream> input_data =
		std::ios_base::in | std::ios_base::binary);

Aws::S3::Model::PutObjectOutcome outcome = s3_client.PutObject(putObjectRequest);
However when I compile it comes up with this error
Error	C2440	'initializing': cannot convert from 'std::shared_ptr<aws::fstream>' to 'std::shared_ptr<aws::iostream>'
I can't for the life of me figure out what I've done wrong as I've literally copied this verbatim from the website.

What I have tried:

I've discovered that IOStream and FStream aren't interchangeable, which was my first thought and after that I literally have no idea as all the examples on the web are identical to what I have.

Any help much appreciated.

Can you provide the link to the place you copied it from?

1 solution

Try including fstream at the top and that should solve the problem.
