While building azure-iot-gateway-sdk on Ubuntu 16.04 using cmake, got error for uamqp.

CMake Error at gatewayFunctions.cmake:170 (message):

After digging deep for that error, found that "LogError" function is called multiple times in azure-iot-gateway-sdk\deps\uamqp\src\cbs.c & header_detect_io.c
After including "azure_c_shared_utility/xlogging.h" in both the file that error was gone but now another error came up. Here is the error messages observed in error.txt

Is the 'azure-iot-gateway-sdk' code useful? Can you please confirm if this is an issue or I am missing something?

@amoldixit-Git - what are you trying to build here?

• The azure-iot-gateway-sdk code is for our Edge gateway v1. If you're building an Edge device (e.g. one that typically sits between devices on an internal network and the broader Internet) you should really be on V2 (https://github.com/azure/azure-iotedge). I'll forward this issue onto Edge team in meantime. If you use V2 Edge, even though we open source it there's considerably easier packaging technologies to get up and running with it.
• This repro is for the C SDK, which is a lightweight SDK for running on embedded devices. Here you'd want to clone https://github.com/Azure/azure-iot-sdk-c with a --recursive and you should get going.

Hello @amoldixit-Git,

The Edge V1 code relies on submodules to pull in its dependencies. That error looks like the submodules did not get initialized. Running git submodule update --init --recursive will probably clear up this error. If you are still having trouble, please raise an issue here: https://github.com/Azure/iot-edge-v1

What @jspaith wrote applies as well. the V1 Edge is an SDK intended for users creating modular, extensible gateway software, but unless you are on a very constrained system, you may want to consider looking at the V2 gateway.

Thanks
