symbol not defined in CoinOptServices.jl

[utotch]

Hi, I want to pass options arguments to OsilBonminSolver / OsilCouenneSolver by using JuMP API.

model = Model(solver = OsilBonminSolver(OSOption("time_limit", 10.0)))

But it fails with "UndefVarError: symbol not defined"@CoinOptServices.jl:390.

I'm afraid that "symbol" function in CoinOptServices.jl is deprecated and "Symbol" is correct.

Does anyone know how to recover it?

[Whole sample code]

using JuMP
using CoinOptServices

model = Model(solver = OsilBonminSolver(OSOption("time_limit", 10.0))) # Only this line matters
# model = Model(solver = OsilCouenneSolver(OSOption("time_limit", 10.0))

n = 3
P0=Symmetric(randn(n,n))
q0=rand(n)
r0=0
P1=Symmetric(randn(n,n))
q1=rand(n)
r1=0
@variable(model, x[1:n])
@objective(model, Min, 0.5*x'*P0*x+q0'*x+r0)
@constraint(model, 0.5*x'*P1*x+q1'*x+r1 <= 0)
status = JuMP.solve(model)
@show getvalue(x), model.objVal, status

[Result]

UndefVarError: symbol not defined
