JuMP v0.21 Support #97

Closed ccoffrin closed 4 years ago

ccoffrin commented 4 years ago

The following example,

using JuMP; using ECOS
solver = with_optimizer(ECOS.Optimizer, verbose=0)
m = Model(solver)

seems to result in the following error,

ERROR: MethodError: Cannot `convert` an object of type String to an object of type Symbol
