follow the step ，build is ok，cmd line show me
[100%] Linking Fortran shared library librefprop.so
[100%] Built target refprop
but when i call from python, i got this hint:
unable to load mixture:R410A.MIX
I have already paste the folder: FLUIDS and MIXTURES into usr/local/lib/ with usr/local/lib/librefprop.so
Please show your Python code. You should have a folder containing your librefprop.so, as well as the FLUIDS and MIXTURES folders. Then you give that folder to whatever interface you use.

QUESTION is resolved,maybe it's a bug for this repo。。。
Before resolved ，the Folder structure
centos python3.x
/root/server/refprop/api/api.py
/usr/local/lib/librefprop.so
/usr/local/lib/MIXTURES
/usr/local/lib/FLUIDS
After resolved ，the Folder structure
/root/server/refprop/api/api.py
/usr/local/lib/librefprop.so
/root/server/refprop/api/MIXTURES
/root/server/refprop/api/FLUIDS
and I make a dll file by netcore，it's also need MIXTURES and FLUIDS with it。
So...Is it my error in operation, or That's the way to do it?
Can you turn on the debugging mode with cp.set_debug_level(100)? It might be informative. The first folder setup you propose is how things should work.

What version of CoolProp? I fixed a bug with the case of the FLUIDS and MIXTURES folders (now I recommend you make both uppercase)
Version: CoolProp-6.4.1-cp36-cp36m-manylinux1_x86_64.whl
and the folder on disk is UPPERCASE，cmdline show lowercase....
Can you try with the development version of CoolProp? The case was fixed here: CoolProp/CoolProp@9e5b4da
emm。。。。 so sorry。。。i donot know how to compile those files....
You want the "if you dare" option here: http://www.coolprop.org/coolprop/wrappers/Python/index.html#automatic-installation
