SCIP not working on Windows

[avinashresearch1]

Hi. I tried installing Julia on windows to demo SCIP but running optimize! fails and so does ]test SCIP. It works perfectly on linux.

     Testing Running tests...
#= C:\Users\avinashs\.julia\packages\SCIP\QEPsa\test\runtests.jl:6 =# @eval(SCIP, libscip) == SCIP_jll.libscip = true
SCIP_PaPILO_jll.is_available() && #= C:\Users\avinashs\.julia\packages\SCIP\QEPsa\test\runtests.jl:7 =# @eval(SCIP, libscip) == SCIP_PaPILO_jll.libscip 
= false

The same problem.

Under win10, with SCIPOptSuit 8.0.1, Julia 1.6.7 installed. Using Julia package SCIP v0.11.4, JuMP v1.3.1.

Besides, I also wonder why I have installed SCIPOptSuit (with env:path set to SCIPOptSuit 8.0.1\bin), dlls under %USERPROFILE%\.julia\artifacts\08af979d049d4b61a282acfbe2e12e36329f06c7\bin are still used.

Thanks!

@eval(SCIP, libscip) == SCIP_jll.libscip = true indicates that the artifact is still used indeed. You need to set the SCIPOPTDIR to the path where SCIP was built, then build with the Pkg command

My mistake!!! After using local SCIP, everything works well!

perfect!
