For displaying a PCloud gallery on a screen.
It seems like the target we're aiming for is armv7-unknown-linux-gnueabihf. Cross-compilation only seems to work by using the cross tool and manually adding a dependency on openssl with a vendored feature (which compiles and statically links to its own openssl). Build with
cross build --release --target=armv7-unknown-linux-gnueabihf
Then run the ansible script:
ansible-playbook -i hosts.ini rpi_playbook.yaml -e PHOTOFRAME_USERNAME=$PHOTOFRAME_USERNAME -e PHOTOFRAME_PASSWORD=$PHOTOFRAME_PASSWORD -e PHOTOFRAME_OAUTH_TOKEN=$PHOTOFRAME_OAUTH_TOKEN
Where hosts.ini looks like
[raspberrypi]
192.168.xx.xxx ansible_ssh_user=pi ansible_ssh_pass=<pass>
Turns out, cross-compiling while linking to external libraries is a nightmare. As of this commit, I have something that works, and the only real downside is that I have to manually include an openssl crate in my dependencies. This well-written blog post has some more tips and tricks that I'd like to try.
The PCloud docs are completely insane: they are inconsistent, often blatantly incorrect, always deeply aggravating.
What I've ended up with is this:
- In your browser, navigate to https://eapi.pcloud.com/oauth2/authorize?client_id=CLIENT_ID&response_type=code, and copy the code.
- Next, navigate to https://eapi.pcloud.com/oauth2_token?client_id=CLIENT_ID&client_secret=CLIENT_SECRET&code=CODE
- Write down the access token and use that in your application.
