> [CoolProp](http://www.coolprop.org/), Is an open-source, cross-platform, reference-quality fluid property database that mirrors many of the functionalities of REFPROP. The codebase is written in C++ and wrappers are available for Python and C#. A DLL is also available for calling from other languages. It is currently the only open-source package that implements the extended corresponding states model for transport properties.

* * *

I’m pleased to announce that **CoolProp** is currently preparing itself to be a Julia registered package, [discussion here] ([CoolProp.jl as a registered Julia package · Issue #1293 · CoolProp/CoolProp · GitHub](https://github.com/CoolProp/CoolProp/issues/1293#)). Most recent works is pushed [here](https://github.com/vimalaad/CoolProp.jl) (Need your contribution).

Any advice and suggestions will be greatly appreciated  
Regards  
[Reza Afzalan](https://github.com/DANA-Laboratory/ThermodynamicsTable.jl)

This is awesome! Thanks. Coolprop is one of the things I’ve been missing most  
since switching mostly away from python.

@DANA-Laboratory, did you mean to link to  
[https://github.com/vimalaad/CoolProp.jl](https://github.com/vimalaad/CoolProp.jl) rather than  
[https://github.com/coolprop/CoolProp.jl](https://github.com/coolprop/CoolProp.jl) ? What still needs to happen before  
you’re comfortable registering the package?

Yep, I saw that discussion. Still not entirely clear to me what needs to be done  
before its ready to be registered. I want to know if there’s something I can do  
to help.

For me it was ready at the time, the only thing was I do not have enough free time to support this kind of works, although I love it.

In Julia 0.7, I had no problems with installing CoolProp, but in 1.0.1 I cannot make it work. This is the output when I do, in the REPL (see below), Pkg.Clone(“[https://github.com/vimalaad/CoolProp.jl.git](https://github.com/vimalaad/CoolProp.jl.git)”)

Can you help?

Thanks!

If I use the standard route as above I now get errors during precompiling:

I also had difficulty installing CoolProp. Not the same error you have. After much trial and error, I think the following got it working for me.

delete all previous attempts to install  
delete .julia/registries/General  
dev [https://github.com/CoolProp/CoolProp.jl.git](https://github.com/CoolProp/CoolProp.jl.git)  
use git GUI to switch to origin/master branch and create tracking branch  
]build CoolProp  
using CoolProp

This still throws a warning about Libdl not being listed in CoopProp’s dependencies, but it runs anyway. It does not pass it’s own tests. ]test CoolProp fails, but the examples provided in the docstrings work.

I got it to install just fine by adding

- DataStructures
- Compat
- Libdl
- JSON

Then,

```julia
Pkg.clone("https://github.com/CoolProp/CoolProp.jl.git")
Pkg.build("CoolProp")

```

It installed with no problems on 1.0.2 and 1.2.0-DEV.21

I still get the same errors when typing “using CoolProp”. Adding and building goes fine. It is the precompiling of CoolProp where I get the error messages.

I’m a fan of this solo effort project(real preliminary)  
[https://github.com/longemen3000/LavoisierCore.jl](https://github.com/longemen3000/LavoisierCore.jl)

Looks like they are supporting thermodynamic properties of tertiary, and quaternary mixtures. I don’t think CoolProp does that?

The more the merrier though!
