s3 store support broken?

[implr]

Despite nix being emerged with USE=etc-profile gc s3 sodium, attempting to access a s3 based store fails, eg.:

$ nix ping-store --store 's3://BUCKET'
error: don't know how to open Nix store 's3://BUCKET'

This seems to be a problem with the ebuild - nix from nix-shell -p nix does work - but that doesn't fix s3 being broken in nix-daemon.

I'm notvery familiar with s3 backend, but I suspect ./configure did not detect a library for you. Can you attach your nix's build.log so we could check what was discovered?

With the patch above it seems to work for me:

$ nix ping-store --store 's3://BUCKET'
error: AWS error fetching 'nix-cache-info': The specified bucket does not exist

[implr]

Unfortunately doesn't seem to work still, configure says checking for aws/s3/S3Client.h... no full log here: https://gist.github.com/implr/3c990998a883f1f71ae3f17a7889a7f7

Ah, wait, I have dev-libs/aws-sdk-cpp installed with USE=-s3 (seems to be the default). Will recompile and try again.

[trofi]

I don't have USE=s3 either. Can you also upload your config.log? I wonder why header did not work for you as is.

We'll also need to turn this failure into a configure failure instead of silent feature removal.

[implr]

That header did not exist on my system with USE=-s3 at all. It did get installed with aws-sdk-cpp with +s3, and after recompiling nix s3 does work now. Now I wonder why it worked for you, or where did you get the header from on your system, heh

[trofi]

Oh, now I see the failure as well /o. It's because I installed dev-libs/aws-sdk-cpp[s3] initially as a one-off run of 'USE=s3 emerge -v1 nix' and it pulled a header for me. But not I updated the @world.

[trofi]

Should be fixed now.
