Problems to build CPLEX

Specific Domains Optimization (Mathematical)
1

Dear all,
I am having a problem to build the CPLEX v 20.10 on my computer. The error message appears:

Pkg.build("CPLEX")
   Building CPLEX → `C:\Users\Usuário\.julia\packages\CPLEX\DgohF\deps\build.log`
┌ Error: Error building `CPLEX`:

Could anyone can help me please?

Which version of CPLEX.jl are you using ?
What is the value of the CPLEX_STUDIO_BINARIES environment variable ?
Did you follow the install instructions ?

3

CPLEX version 20.10
Yes I have followed exactly the instructions:

ENV["CPLEX_STUDIO_BINARIES"] = "C:\\Program Files\\CPLEX_Studio1210\\cplex\\bin\\x86-64_win\\"
import Pkg
Pkg.add("CPLEX")
Pkg.build("CPLEX")
4

By CPLEX.jl, I mean the version of the CPLEX Julia package, you get it with Pkg.status("JuMP"). The latest version of CPLEX.jl gives more details on why the build failed. Moreover, older version of CPLEX.jl do not support CPLEX v20.1

5

Sorry,

[a076750e] CPLEX v0.6.6
[4076af6c] JuMP v0.21.3

I have update all packages now.

6

CPLEX v20.1 is not supported by CPLEX.jl v0.6.6, the latest version of CPLEX is v0.7.6.
Try Pkg.add(Pkg.PackageSpec(name="CPLEX", version="0.7.6")) (not that you should restart Julia in order to use the new version.

Not yet:

Sorry, I meant v0.7.6, not v0.7.7 (I have edited the command in my previous post)

9

No work yet. There isn’t this version. Thank you for attention.
Maybe, in future CPLEX 20.1 works on this latest version,

10

This function exists, maybe it conflicts with other packages you have. Can you give the error you get when you run Pkg.add(Pkg.PackageSpec(name="CPLEX", version="0.7.6")) ?

11

Something very strange:

julia>  Pkg.add(Pkg.PackageSpec(name="CPLEX", version="0.7.6"))

It’s indeed quite weird as JSONSchema is not listed in the packages depending in VegaLite: JuliaHub.
As a workaround, you can create a local environment: 4. Working with Environments · Pkg.jl.
In this environment, you will only add the packages you need so you won’t have incompatibilities between packages you use for different projects.

There is a compatibility issue with Vegalite: https://github.com/queryverse/VegaLite.jl/issues/345

Run import Pkg; Pkg.rm("VegaLite"); Pkg.add("CPLEX"); Pkg.update(). Then restart Julia for the changes to take effect.

] add CPLEX#master

Now, CPLEX version CPLEX v0.7.6 works and was installed.

Oops. Yes, I fixed VegaLite but forgot to reply here to tell you.
