Missing conda dependency spdlog

[giotherobot]

Trying to run the WalkingModule from the followig pixi env:

[workspace]
authors = ["Giovanni Fregonese <giotherobot@gmail.com>"]
channels = ["conda-forge", "robotology"]
name = "gazebo_env"
platforms = ["linux-64"]
version = "0.1.0"

[tasks]

[dependencies]
yarp = ">=3.12"
whole-body-estimators = "*"
bipedal-locomotion-framework = "*"
ergocub-software = "*"
walking-controllers = ">=0.9"
gz-sim-yarp-plugins = "*"

results in:

pixi run WalkingModule
/home/giovannif/gazebo_env/.pixi/envs/default/bin/WalkingModule: error while loading shared libraries: libspdlog.so.1.15: cannot open shared object file: No such file or directory

Is spdlog a dependency of WalkingControllers?

Trying to pixi add spdlog results in an incompatible version since WalkingControllers 0.9 looks for libspdlog 1.15 but other dependecies require spdlog>=1.16, adding spdlog = ">=1.15.0, <1.16.0" works and the WalkingModule can run.

This is probably a case of what is discussed in conda-forge/pinocchio-feedstock#150 . In a nutshell, walking-controllers depends transitively on spdlog via blf, as blf includes spdlog in its headers. However, conda does not provide ways of expressing that (something is being developed in conda/ceps#77 and conda/ceps#129) so for now the only solution is to add the spdlog dependency on walking-controllers directly.

We can do a rebuild of the robotology packages with the additional spdlog dep, but in the meanwhile the workaround that you identified is the correct one.

Done in robotology/robotology-superbuild#1926 .
