Hi Team,
How to fix this error : Connection failed with error aws-c-io: AWS_IO_SOCKET_UNSUPPORTED_ADDRESS_FAMILY, Socket, unsupported address family.

That error is generated by a failed system call. You can see the error mappings here:

• Linux - https://github.com/awslabs/aws-c-io/blob/e762fd250589dfa98a9cce9c3ffca3414d99fdda/source/posix/socket.c#L131-L132
• Windows - https://github.com/awslabs/aws-c-io/blob/e762fd250589dfa98a9cce9c3ffca3414d99fdda/source/windows/iocp/socket.c#L662-L663

You'll likely need to dig into OS documentation and SDK logs to diagnose the problem.

I had reported an issue #109 few years back. Now I am trying sdk (cross sompiled) in different hardware platform here as well I have same issue. Changing hints.ai_family to AF_INET solves the problem. is it right way to fix that issue or are there any other recommended workaround?

My unfortunately-unhelpful answer boils down to "we only officially support glibc and musl as linux libc targets." uclibc (assuming that is still a part of your target platform) appears to be abandoned. I have not tried it directly, but it's my understanding that the SDK should (unofficially) work with uclibc-ng because I know we have people using the SDK in buildroot-based projects.

The easiest solution for you is probably just to go with the small patch that fixes the issue for you.
