You could try the following:
using Libdl
Libdl.dlopen("ENTER_PATH_TO_liblapack.so.3", RTLD_GLOBAL)
prior to your code snippet and do the same for following errors (i.e. if symbols related to other libraries are undefined). Not sure if that's the best/recommended way, but I think it might do the trick.

Compiling the HSL libraries and getting everything linked can be finicky. If you have improvements to the instructions, please open a PR.

I will make a PR, but let's see first if this works out :D

@bennerh
I had the exact same problem this afternoon when I tried to use the configure
script of coinhsl
.
The issue is how they generate the shared library.
https://discourse.julialang.org/t/incorrect-objective-type-when-using-ma57-with-ipopt-in-jump/90578/8
I also have an Ubuntu OS for information.
I just released a new version of HSL.jl (0.3.5) to compile it automatically if it can help.

Thanks a lot, this solved the issue!
The following code is running!
Libdl.dlopen("/usr/lib/x86_64-linux-gnu/lapack/liblapack.so.3", RTLD_GLOBAL)
Libdl.dlopen("/usr/lib/x86_64-linux-gnu/libmetis.so", RTLD_GLOBAL)
model = Model(Ipopt.Optimizer)
set_optimizer_attribute(model, "linear_solver", "ma57")
@variable(model, 0 <= x <= 2)
@variable(model, 0 <= y <= 30)
@objective(model, Max, 5x + 3 * y)
@constraint(model, con, 1x + 5y <= 3)
optimize!(model)
from ipopt.jl.
Do any of you see problems with this approach?
If not, I could make a PR to include something like this in the instructions.
from ipopt.jl.
At least on an hpc cluster, I encountered the same problem despite metis and lapack being on the load path.
just running:
dlopen("liblapack.so.3", RTLD_GLOBAL)
did the trick for me.
Considering that metis and lapack are usually on the load path, we could also conceive something that takes care of the rest for users in the Ipopt.jl code directly.
But tbh, I neither really have a clue why this works (except that ipopt and linear solvers are now able to access the library symbols, but the real question is why they weren't before), nor if the RTLD_GLOBAL
flag could produce other unforeseen problems downstream...
from ipopt.jl.
Here's a sneak peek of some improvements that @amontoison has coming up (not released yet):
julia> using JuMP
julia> import Ipopt
julia> import HSL_jll
julia> model = Model(Ipopt.Optimizer)
A JuMP Model
Feasibility problem with:
Variables: 0
Model mode: AUTOMATIC
CachingOptimizer state: EMPTY_OPTIMIZER
Solver name: Ipopt
julia> set_attribute(model, "hsllib", HSL_jll.libhsl_path)
julia> set_attribute(model, "linear_solver", "ma97")
julia> @variable(model, x)
x
julia> @objective(model, Min, (x - 2)^2)
x² - 4 x + 4
julia> optimize!(model)
This is Ipopt version 3.14.4, running with linear solver ma97.

I think this should resolve all of our HSL problems.
from ipopt.jl.
Have HSL changed their license? They never allowed binary redistribution except for the newest SPRAL solver, as far as I remember.
from ipopt.jl.
Nop but we can create artifacts without Yggdrasil 😉
You will understand when it will be released.
from ipopt.jl.
Yeah the plan is that it'll require a manual (licensed) download of HSL_jll
, which you can extract to a directory, and then run ] dev /path/to/hsl
. From then on, you can run import HSL_jll
and we'll load the libraries etc.
That means that we're downloaded compiled binaries, so we never have to compile on a user's machine.
from ipopt.jl.
The downloading of compiled binaries is what I meant by binary redistribution, which I always thought was disallowed by the HSL license. https://licences.stfc.ac.uk/product/coin-hsl
2.1.2
the Licensee may not distribute any of the Software to any third party, or share its use with any third party (regardless of whether such third party is from the same institution), and the Licensee may not sub-license the use of any of the Software;

It'll be an official download from https://licences.stfc.ac.uk
.

No, the license just says that you can't distribute the HSL package under any form. But for you own application on your computer you can do what you want with it.
Until now it was only possible to download the source code. The new package will have the source files and precompiled versions (under a user-friendly form for Julia users) but as before it must be only available for you.
from ipopt.jl.
If it's the HSL people hosting the download as an official part of what they license people to obtain directly from them, that works. Anyone other than them putting the files up somewhere else like on github releases wouldn't be allowed without some special arrangement that gets around that distribution prohibition.

Yes, this is the plan. @amontoison has been working with them directly.
from ipopt.jl.
I'm going to close this in favor of #247 for now.
The underlying problem in this issue was an upstream issue with the HSL configure
script. We're about to release official binaries from HSL, which will render this issue moot. And with a much simple installation path, I'll be able to update the documentation in the README and close #247 for good.
