Getting ReadOnlyMemoryError

[mdpradeep]

I am getting the following error with the new version.

Version:

julia> Pkg.status("Ipopt")
 - Ipopt                         0.2.6

CC @abelsiqueira (the only change of substance between 0.2.5 and 0.2.6)

[abelsiqueira]

Hello @mdpradeep, can you show the tests on 0.2.5?

[joaquimg]

I had the same error installing a Ipopt.jl in a brand new Windows computed yesterday, (no problems in MAC, haven´t tested on linux)

However I updated my old computer´s Ipopt and it still worked.

@abelsiqueira I tested checking out a different version of Ipopt.jl to run the test and the result is the same above.

It does not seem to be a julia issue, because the (only) fix to the problem was copying the WinRPM deps (which include ipopt executable) from the old computed to the new one.

I think the issue is related to either WinRPM or the Ipopt executable.

[mdpradeep]

Thanks @joaquimg. On my system earlier versions are failing as well. The earlier versions were working on the same system before. As you mentioned it might be a WinRPM issue.

[tkelman]

@mlubin I'm watching this repo, no need to ping specifically.

We should try turning up the print level in the ipopt options, and/or adding some debug output to the user-defined functions to see exactly where this is happening.

[mdpradeep]

The parameter passed to the C call is:

prob = Ipopt.IpoptProblem(Ptr{Void} @0x0000000007271000,4,2,[1.0,5.0,5.0,1.0],[0
.0,0.0],[0.0,0.0],[0.0,0.0,0.0,0.0],[0.0,0.0,0.0,0.0],0.0,0,eval_f,eval_g,eval_g
rad_f,eval_jac_g,eval_h,nothing,:Min)

The ccall made is:

ret = ccall((:IpoptSolve, libipopt),
    Cint, (Ptr{Void}, Ptr{Float64}, Ptr{Float64}, Ptr{Float64}, Ptr{Float64}, Ptr{Float64}, Ptr{Float64}, Any),
    prob.ref, prob.x, prob.g, final_objval, prob.mult_g, prob.mult_x_L, prob.mult_x_U, prob)

Let me know if you need any more information.

[xximranxx]

Just fyi, I also have the exact same issue on Windows 7, installed Ipopt today with newest julia release (0.5.0)

[mlubin]

CCing @yuyichao @ihnorton @vtjnash who may have a better idea of what could cause the ReadOnlyMemoryError() from the ccall.

[mlubin]

I've reproduced the issue locally on both Julia 0.4 and 0.5, so something has certainly changed in the WinRPM binaries.

[xximranxx]

Just bumping...
Is there any idea how I could at least temporarily get Ipopt to work?
I am on the verge of convincing my employer to adopt julia and I need to demonstrate Ipopt for this
Thanks for any help

[mlubin]

The most effective solution at this point would be to contact Julia Computing for professional support, since they have the expertise to fix this issue.

happening in libstdc seems to indicate a library conflict.
