AWS SDK CPP would not compile
Plugging away on a project where I need to reference the C++ SDK for AWS. I’m working on a small t3a.micro instance and this is how how the commands went:
~/sdk_build$ cmake ../aws-sdk-cpp -DCMAKE_BUILD_TYPE=Debug -DCMAKE_PREFIX_PATH=/usr/local/ -DCMAKE_INSTALL_PREFIX=/usr/local/ -DBUILD_ONLY=”s3″

Hmm, that seems odd. I have a note on what commands to run and these commands ran fine on another server only yesterday. I removed the cloned aws-cdk-cpp folder and tried again. Same thing. Maybe I’m missing something else?
I started stepping through my documents and noticed:

Ha! I hadn’t noticed that before. The git clone failure doesn’t show up in red and I was busy doing other things and didn’t notice the failure. The next command that I would run would be the cmake above, so of course it failed because the git clone failed. Now how to fix this?
Based on a memory related comment here, I decided to increased my AWS EC2 instance size from a t3a.micro to a t3a.small. And that was it. The git clone now works fine and everything compiled.
