Help I cannot fix this on my Macbook

And what are the errors?

Sorry I forgot to copy it in:

Can you share the output of:

using Pkg
Pkg.status()

?
Does it work if you install it in a new project:

mkdir test
cd test
julia --project=.

and then in Julia:

using Pkg
pkg"add Clp"

?

I cannot run `Clp` through `JuMP`, it crashes when as soon as I start the optimi…zation. Here is a minimal example, where I am trying to minimize `c^T x` where `A x = b` and `x >=0`. ``` julia> using JuMP, Clp julia> C =[-2.0,3.0,0.0, 0.0] 4-element Vector{Float64}: -2.0 3.0 0.0 0.0 julia> A=[1.0 1.0 1.0 0.0; 1.0 -1.0 0.0 1.0] 2×4 Matrix{Float64}: 1.0 1.0 1.0 0.0 1.0 -1.0 0.0 1.0 julia> b= [4.0,6.0] 2-element Vector{Float64}: 4.0 6.0 julia> model = Model(Clp.Optimizer) A JuMP Model Feasibility problem with: Variables: 0 Model mode: AUTOMATIC CachingOptimizer state: EMPTY_OPTIMIZER Solver name: Clp julia> @variable(model,x[1:4]>=0) 4-element Vector{VariableRef}: x[1] x[2] x[3] x[4] julia> @objective(model,Min,C'*x) -2 x[1] + 3 x[2] julia> @constraint(model,A*x.==b) 2-element Vector{ConstraintRef{Model, MathOptInterface.ConstraintIndex{MathOptInterface.ScalarAffineFunction{Float64}, MathOptInterface.EqualTo{Float64}}, ScalarShape}}: x[1] + x[2] + x[3] = 4.0 x[1] - x[2] + x[4] = 6.0 julia> optimize!(model) julia(91740,0x100cd8580) malloc: *** error for object 0xe00000000000000: pointer being freed was not allocated julia(91740,0x100cd8580) malloc: *** set a breakpoint in malloc_error_break to debug signal (6): Abort trap: 6 in expression starting at REPL[9]:1 __pthread_kill at /usr/lib/system/libsystem_kernel.dylib (unknown line) Allocations: 46636441 (Pool: 46623528; Big: 12913); GC: 37 fish: Job 1, 'julia' terminated by signal SIGABRT (Abort) ```

The solution is not to use Clp on aarch64-darwin. I believe @odow suggests using HiGHS instead.

The latest version of Clp.jl will throw an error in __init__:

"Clp.jl does not support Apple M-series processors. Please use HiGHS.jl instead."

Messaging in __init__ isn’t helpful if the package fails to precompile and thus cannot be loaded.

Thanks ^^

Ah there’s something about assuming… I’ve now skipped the recompilation and tested (this time) that it actually works:

(clpjl) pkg> st
