I just had an issue with bazel builds failing, since the official libeigen repo is experiencing issues right now:
fatal: repository 'https://gitlab.com/libeigen/eigen.git/' not found WARNING: errors encountered while analyzing target '//apps/tutorials/ping:ping': it will not be built INFO: Analyzed target //apps/tutorials/ping:ping (73 packages loaded, 4672 targets configured). INFO: Found 0 targets... ERROR: command succeeded, but there were loading phase errors INFO: Elapsed time: 263.694s, Critical Path: 0.02s INFO: 0 processes. FAILED: Build did NOT complete successfully
As a temporary fix, edit
/isaac/engine/third_party/engine.bzl to use gitlab.com/cantonios/eigen instead:
... remote = "https://gitlab.com/cantonios/eigen.git", ...
Then try building again.
