Hello Guix! I'm afraid I broke r-v8 and a few of its dependants by updating node, sorry about that! AFAIK, the new node uses a function from nghttp2 1.41 that's not present in 1.40, `nghttp2_option_set_max_settings'. However, since curl depends on nghttp2 we've grafted 1.40 -> 1.41 to avoid a full rebuild. Looking at r-v8's log [0], it complains that the symbol is missing, indicating it's trying to link with the old version 1.40. I /believe/ it's inherited it through r-curl. I'm not sure how to fix this, I'm happy to revert the node update if needed, let me know! Then we'd have to wait for the next core-updates cycle so that we no longer graft nghttp2. Unless somebody has a better idea? Thanks, Pierre [0]: https://ci.guix.gnu.org/log/62nkhf9dnlzgw3dz9khd79khqdpaib79-r-v8-3.2.0
