Crash When Optimizing about scip.jl

[matbesancon]

Hello,

Can you give us a bit more details on:

• what version of Julia, what OS you are on?
• The full minimal example?
• What is the error message?

[HilaireFoillard]

I was using Julia on a jupyter notebook, Julia 1.8.0-rc4 , and I work on a windows 11 os

[matbesancon]

once you have the windows SCIP installed, you can set the environment variable SCIPOPTDIR and build SCIP, it should be sufficient

[matbesancon]

The issue you encountered is documented in the readme, the automatic version does not work yet on windows:
https://github.com/scipopt/SCIP.jl#custom-scip-installations

[HilaireFoillard]

I tried it but I didn't succeed .
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 ).

[matbesancon]

Is there not a $SCIPOPTDIR/lib/scip.dll?

Don't see it.
Note that my way is SCIPOptSuite 8.0.2/lib/....

[HilaireFoillard]

But I have a SCIPOptSuite 8.0.2/bin/libscip.dll

[matbesancon]

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
Then I build SCIP and I have this issue

[HilaireFoillard]

The following package names could not be resolved:

• SCIP (not found in project or manifest)

[matbesancon]

yes you need to add the environment variable SCIPOPTDIR, then add and build SCIP

[HilaireFoillard]

Nice that time it works

[matbesancon]

perfect!

Closing this, if you feel the docs in the README could be improved for windows, a PR is welcome :)
