I randomly encounter the following error only in Linux (Mac doesn’t show this error) when I try to solve a linear programming by JuMP and Clp:
julia: symbol lookup error: /home/paalon/.julia/packages/Clp/GpVOR/deps/usr/lib/libClp.so: undefined symbol: dgetrf_
The versions of Julia and packages are:
I cannot understand the meaning of this error and I fail to determine the reason why this error occurs randomly. Does anyone have any information?
I just ran into this crash today. I’m mostly lost as well but I can say that JuMP has nothing todo with it. Also I can reliably reproduce it, although it takes in the order of 20 minutes to get there. Running under gdb didn’t give me a backtrace (“no stack”). I’ll see if I can isolate the last call into Clp and see if that’s sufficient to reproduce the crash on its own.
It was sufficient. Now I can get the crash in a few minutes from
using MathProgBase.SolverInterface, Clp, JLD2, SparseArrays
@load "clpcrash.jld2" data
model = LinearQuadraticModel(ClpSolver())
loadproblem!(model, data...)
optimize!(model)
with a 28 MB data file.
