Could you provide code that exhibits the failure?
I used the double pendulum example and Acrobot example.
Tests pass both locally (on both OSX and Linux) and on Travis, and they include various calls to simulate
, as well as running all of the notebooks.
I'll need more to work with. I'm not clear on what code 'the double pendulum example and Acrobot example' exactly refers to. Could you post:
versioninfo()
Pkg.status()
The tests pass locally here too, however when I run any code calling the simulate function the error happens. An example code I used follows below, but I also tested using https://github.com/tkoolen/RoboticsJuliaCon2017.jl/tree/master/notebook
using RigidBodyDynamics
urdf = "urdf/doublependulum.urdf"
mechanism = parse_urdf(Float64, urdf)
state = MechanismState{Float64}( mechanism)
times, joint_angles, joint_velocities = simulate(state, 5.)

Hmm, I still can't reproduce this, neither on OSX nor on Linux. To be clear, I'm on RigidBodyDynamics 0371c566f977ad1b01a173e7a6c602d0e80d2e95, and I did change "urdf/doublependulum.urdf"
in your example code to "urdf/Acrobot.urdf"
because I don't have a "doublependulum.urdf"
. But you mentioned that the same thing happens with "Acrobot.urdf"
.
I noticed in your versioninfo
that you're using
BLAS: libblas
LAPACK: liblapack
LIBM: libm
whereas I have
BLAS: libopenblas (USE64BITINT DYNAMIC_ARCH NO_AFFINITY Haswell)
LAPACK: libopenblas64_
LIBM: libopenlibm
Also, your commit is 903644385b*
, whereas mine is 9036443
(no star). I'm assuming the star means local modifications that weren't committed, and that you compiled Julia from source. Could you try with the generic Linux binary downloaded from the Julia website?
By the way, the stack trace appears to be similar to https://github.com/JuliaLang/julia/issues/21244.
For completeness, here is my test setup on Linux:

Hi It really is not a problem with the package itself, it's a problem with LLVM https://github.com/JuliaLang/julia/issues/19792.
Thank you! :D
Thank you very much for the update. Just so that I understand fully, was this because you compiled Julia against a vanilla version of LLVM that didn't include the patches from https://github.com/JuliaLang/julia/pull/19810?
I use Manjaro (based on Arch linux), julia is in the package manager of it. However since the Arch is rolling-release system, the error may have occurred after a system update. Some people reported that same problem on Slack, including problems similar to the ones I had when I installed DrakeVisualizer.
The simulation function returns
Tests performed on two different computers.
