Richard Feldman (Sep 12 2021 at 02:52):haven't seen that one before! can you post the full console output?
Dull Bananas (Sep 12 2021 at 03:57): Richard Feldman (Sep 12 2021 at 03:58):hmm, what OS are you running?
Richard Feldman (Sep 12 2021 at 03:59):I guess macOS based on the mentions of homebrew in the trace
Dull Bananas (Sep 12 2021 at 04:00):ubuntu 20.04.2 lts
Richard Feldman (Sep 12 2021 at 04:01):interesting! ok try apt-get install libxkbcommon-dev and see if that fixes it?
Richard Feldman (Sep 12 2021 at 04:01):ha, I just noticed we have that in our Earthfile but not in BUILDING_FROM_SOURCE.md :sweat_smile:
Dull Bananas (Sep 12 2021 at 04:15):it now works :poop:
Richard Feldman (Sep 12 2021 at 04:22):great! made a PR to add it to the instructions: https://github.com/rtfeldman/roc/pull/1691
Folkert de Vries (Sep 12 2021 at 09:01):ah yes, this is now needed. I don't entirely know why though? The lib seems to do keyboard event handling. @Anton is this for the editor? I first had to install it while working on the wasm stuff but that should not do anything with the keyboard
Anton (Sep 12 2021 at 09:35):I'm not sure which library requires it, I've been adding changes to the editor-let-value branch and not to trunk for a long time so I would guess it's not because of the editor. But I often specify only major and minor version number of editor dependencies so it could be that there was an unnoticed update with a patch version that required the library for a fix.
Brendan Hansknecht (Sep 12 2021 at 15:55):It's needed by the copy paste library of the editor
Brendan Hansknecht (Sep 12 2021 at 15:56):xcb v0.9.0
└── x11-clipboard v0.5.2
└── copypasta v0.7.1
└── roc_editor v0.1.0 (/home/brendan/Projects/roc-misc/roc/editor)
