Gamelift InitSDK Error on Amazon Linux 2023

Question

I am getting an invalid attempt to read memory error when starting my unreal engine server on amazon linux 2023. I am using the 5.1 sdk which i have compiled using an amazonlinux 2023 container and placed the .so file within the unreal engine plugin.

Answer

Hi Micah,

Thanks for raising this concern. Unreal Engine statically links OpenSSL into the server executable, which causes version conflicts with OpenSSL being used with the GameLift Server SDK on Amazon Linux platforms. To mitigate this, it is recommended to use the same version of OpenSSL that Unreal Engine uses. Ureal Engine 5.1 uses [OpenSSL 1.1.n](https://www.openssl.org/source/old/1.1.1/). But it is recommended you verify if this is indeed the version your Unreal Engine is using.

Once you have built your GameLift server, please ensure you copy the `.so` files for OpenSSL into the packaged bundle, namely `libcrypto.so.1.1` and `libssl.so.1.1`. These can be placed in the same location as the GameLift Server SDK library `libaws-cpp-sdk-gamelift-server.so`.

We are currently working on improving this experience by updating our public documentation to include more detailed instructions. Hope this helps!
