Hi @gi12345 can you send the cmake command line that you used to build? |

This is part of a very large system. We do not use cmake, all is built through make. |
Also, look at this one:

You are setting the ClientConfiguration outside CMotionUploader() {
InitAPI(options);
{
Aws::Client::ClientConfiguration clientConfig;
}
} |

Hi Daniel,
In my opinion the problem is caused by Aws::Client::ClientConfiguration m_cfg. I guess it is bound to an AWS internal constructor which runs prior to Aws::InitAPI(m_awsSDKoptions). C++ compiler performs class member variable handling prior to invoking class constructor method.If the class member variable definition Aws::Client::ClientConfiguration m_cfg would automatically call Aws::InitAPI() the problem would be solved. |

Hi Daniel, |

As an experiment I have modified my code as follows: Ouput: Crash stack trace: Obtained 10 stack frames: |
|
Reproduced this way: int main(int argc, char** argv)
{
printf("Point qqqqqqqqqqqqqqqqqq1\n");
Aws::SDKOptions k_awsSDKoptions;
Aws::InitAPI(k_awsSDKoptions);
printf("Point qqqqqqqqqqqqqqqqqqqqqq2\n");
{
Aws::Client::ClientConfiguration m_cfg; //xxx-gi
printf("Point qqqqqqqqqqqqqqqqqqqqqqq3\n");

Code always crashes in this variable definition inside AWS SDK: |

in file AWSHttpResourceClient.cpp, Line 134: |

The latest AWS-C++ SDK (started June 1 2022) has linkage errors not seen before in the core.so library: |

Hi Daniel, |
we see the same issue. use aws-sdk-cpp ver. 1.8.816, ubuntu20, use make, Intel 32bits App. The following lists the coredump backtrace and our codes ------ coredump backtrace ------ ----- codes -------- class ApplicationState
{
public:
static ApplicationState& getInstance();
void addClientConfiguration();
private:
Aws::Client::ClientConfiguration* p_awsClientConfig;
}
ApplicationState &ApplicationState::getInstance() {
static ApplicationState appState;
return appState;
}
void ApplicationState::addClientConfiguration() {
p_awsClientConfig = new Aws::Client::ClientConfiguration();
}
main() {
Aws::SDKOptions options;
Aws::InitAPI(options);
ApplicationState::getInstance().addClientConfiguration(); // crash here !!!

Can you make sure that you are making all sdk calls inside the #include <aws/core/Aws.h>
int main(int argc, char** argv)
{
Aws::SDKOptions options;
Aws::InitAPI(options);
{
// make your SDK calls here.
}
Aws::ShutdownAPI(options);
return 0;
