Crash When Optimizing #248
Comments
Hello, Can you give us a bit more details on:
|
I was using Julia on a jupyter notebook, Julia 1.8.0-rc4 , and I work on a windows 11 os |
once you have the windows SCIP installed, you can set the environment variable SCIPOPTDIR and build SCIP, it should be sufficient |
The issue you encountered is documented in the readme, the automatic version does not work yet on windows: |
I tried it but I didn't succeed . |
Is there not a $SCIPOPTDIR/lib/scip.dll?

The sequence of command i have to do is
Pkg.rm("SCIP") to remove the scip package download using Pkg,
add the path of the bin of SCIP on the environnement variable
then build SCIP (do i need to make Pkg.add("SCIP") before? )
Note that I installed the SCIPOptSuite 8.0.2 using the win64.exe way, but
I didn't find $SCIPOPTDIR/lib/libscip.so, $SCIPOPTDIR/lib/libscip.dylib nor
$SCIPOPTDIR/bin/scip.dll ( but I have bin/libscip.dll, bin/scip.exe,
lib/libscip.lib ).

Don't see it. |
But I have a SCIPOptSuite 8.0.2/bin/libscip.dll |
Then the env variable SCIPOPTDIR as your path to the Scipootsuite 8.0.2
repo should work

I put this value for SCIPOPTDIR : C:\Program Files\SCIPOptSuite 8.0.2\bin Then i remove SCIP |
The following package names could not be resolved:
|
yes you need to add the environment variable SCIPOPTDIR, then add and build SCIP |
Nice that time it works |
perfect! |
Closing this, if you feel the docs in the README could be improved for windows, a PR is welcome :) |
Hello,
I use to test the SCIP solver on my model on Julia.
This is a very simple LP problem. I have an issue because my model crash when I try to optimize it (m = Model(SCIP.Optimizer) ... optimize!(m) ) So I'm disappointed.
I see that a good way to avoid that is to build SCIP by downloading the solver on the website but I don't understand how to build it after.
Thank you
