I cloned the drake repo and went through the [setup instructions from source][1] (WSL Ubuntu 18.04). Now I am trying to follow the first steps and build:
bazel build //tools:drake_visualizer //manipulation/util:geometry_inspector
However some warnings treated as errors are getting in the way :
bazel-out/k8-opt/bin/systems/framework/_virtual_includes/system_scalar_converter/drake/systems/framework/system_scalar_converter.h: In member function 'void drake::systems::SystemScalarConverter::AddIfSupported()': bazel-out/k8-opt/bin/systems/framework/_virtual_includes/system_scalar_converter/drake/systems/framework/system_scalar_converter.h:138:60: error: 'GuaranteedSubtypePreservation' is deprecated: DRAKE DEPRECATED: Use MakeWithoutSubtypeChecking instead of kDisabled. The deprecated code will be removed from Drake on or after 2021-11-01. [-Werror=deprecated-declarations] AddIfSupported<S, T, U>(GuaranteedSubtypePreservation::kEnabled);
What's the proper way to resolve that? Since those warnings are coming from explicit deprecations I would assume there is a way to cleanly work around them without manually tampering with the BUILD files?
Perhaps there is something different with the WSL toolchain that's tripping us up here?
In any case, it calls my attention to the fact that a bit of stale code has slipped into that function body. I'll work on a fix for that typo https://github.com/RobotLocomotion/drake/pull/15657, and perhaps it will resolve your problem as well.
