c# M2mqtt to AWS IoT c++

[autoprog]

I have a C# M2Mqtt application that works perfect on IoT AWS.

c#

 var clientCert = new X509Certificate2(Path.Combine(AppContext.BaseDirectory, "certificate.pfx"), @"");
 var caCert = X509Certificate.CreateFromCertFile(Path.Combine(AppContext.BaseDirectory, "root.pem"));
 client = new MqttClient(IotEndpoint, BrokerPort, true, caCert, clientCert, MqttSslProtocols.TLSv1_2);
 client.MqttMsgPublishReceived += client_MqttMsgPublishReceived;
 client.ProtocolVersion = MqttProtocolVersion.Version_3_1;
 client.Connect(device_aws_id);
 client.Subscribe(new[] { "topic" }, new[] { MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE });

my file certificate.pfx ok
my file root.pem ok
//-------------------------

but I need to implement Mqtt in a c++ library.

sdk v2 setup ok,
C:\dev\iotsdk\sdk-cpp-workspace ok
use Visual Studio 2019, it see sdk ok

Does any partner have an example that works.
which example looks like my code.

thanks,
Carlos.

Have you taken a look at our x509_credentials_provider_connect sample? It shows how to connect in c++ with x509 credentials

hi,
jmklix, thanks,
my test, error link2019

Error LNK2019 unresolved external symbol, _aws_mem_acquire, referenced in function "public: char * __thiscall Aws::Crt::StlAllocator::allocate(unsigned int,void const *)"
(?allocate@?$StlAllocator@D@ Crt@Aws@@QAEPADIPBX@Z)
AWSMqttc D:..AWSMqttc.obj 1

trying to solve,

thanks,
Carlos.

The code sample in the original query is just using certificate and private key to connect. The X509 credentials provider is not what they'd want here.
