Lazarus working examples

[Aleksandr Motrev]

Hello for everyone. I try to use coolprop with lazarus, but my programs dont work, I have error 000007b on application start. I have similar issues with delphi/lazarus examples officially published on the coolprop site.

For example this dont work:

program project1;

CONST

  COOL_PROP = 'CoolProp.dll';

  function PropsSI(Output: PAnsichar; Name1: PAnsichar; Prop1: Double; Name2: PAnsichar; Prop2: Double; FluidName: PAnsichar): Double; stdcall; external COOL_PROP name '_PropsSI@32';

var

  h: Double;

begin

     h:=PropsSI('H', 'T', 300, 'P', 101325, 'R134a');

     writeln(h);

     readln;

end.

What I am doing wrong, maybe working examples exist anywhere?

Hi Aleksandr,

did you get the coupling Coolprop-Lazarus to work in the end? If yes, could you share an example?

Best regards,

Matthis

Hi Alexandr,

I am very curious if you succeeded to run Coolprop from Lazarus.

For a simulation model of a H2 refueling station I made in Lazarus, I would need Coolprop to work from Lazarus too!
