AWSSDKCPP with Visual Studio 2017 failure

[JasonLukose]

Using windows 10, with Visual Studio 2017.

I used Nuget to get the SDK and tried running this:

int main(int argc, char** argv)
{
    if (argc != 3)
    {
        std::cout << "Usage: send_message <queue_url> <message_body>" <<
            std::endl;
        return 1;
    }

    Aws::SDKOptions options;
    Aws::InitAPI(options);
    /*{
        Aws::String queue_url = argv[1];
        Aws::String msg_body = argv[2];

        Aws::SQS::SQSClient sqs;

        Aws::SQS::Model::SendMessageRequest sm_req;
        sm_req.SetQueueUrl(queue_url);
        sm_req.SetMessageBody(msg_body);

        auto sm_out = sqs.SendMessage(sm_req);
        if (sm_out.IsSuccess())
        {
            std::cout << "Successfully sent message to " << queue_url <<
                std::endl;sss
        }
        else
        {
            std::cout << "Error sending message to " << queue_url << ": " <<
                sm_out.GetError().GetMessage() << std::endl;
        }

    } */
    Aws::ShutdownAPI(options); 
    return 0;
}

However, it seems that visual studio has linking errors when trying to do InitAPI and shutdownAPI.

There does not seem to be any documentation with Visual Studio 2017

Update: it works with VS2015.

Thanks for reporting this problem. Some of the Nuget packages for vs2017 are missing, we fixed it. It will be available on Nuget soon.

[singku]

Hi, Nuget packages for vs2017 has been updated, Thank you!

[JasonLukose]

Thanks! It works great. I did have to make the reference packages statically linked and not dynamically linked after I re installed the core and sqs. All in all, works well!

[singku]

@JasonLukose What will happen when you dynamically link the libs?

[JasonLukose]

It will error with the following error if both are DLL @singku

Error   LNK2001 unresolved external symbol "char const * const Aws::Http::CONTENT_TYPE_HEADER"
(?CONTENT_TYPE_HEADER@Http@Aws@@3PEBDEB)        

Sorry, saw this late! @singku

@JasonLukose We compiled above code with vs2017 and Nuget package, both dynamic and static link can work just fine. By the way, we select the link method in "Propoerties->Referenced Packages"
