[SOLVED] Cannot find pspice library even if it loads its content

Schematic Simulation (Ngspice)
1

I’m learning how to simulate in Kicad and I’m following some tutorial.
For example I placed an pspice:OPAMP symbol, then I selected the model I downloaded for a TL072:

As you can see it successfully loaded the content of the library file.
But when I run the simulation it says it cannot find the library!

How is it possible?
What should I do in order to fix this?

I set the compatibility mode to ps:

Compatibility modes selected: ps

Check the file and directory permissions first.

They seem ok to me.
But it they were wrong, it could not have loaded the content as shown in the first picture, could it?

Anyway, I tried to set them to 777 but nothing changed.

please post the ngspice netlist here:
Eeschema → Export → netlist → Spice → Export netlist

File attached, thanks.

Problem found.
I had to change the path of the file using an absolute path.
For me it’s a bug: using the select button it should retrieve the path it needs!

The offending line is
.include "MyProject/Development/Kicad/pspice/op184.lib"
It includes a relative path starting with MyProject.
As ngspice is a shared library, the relative path starts with the location of the caller, the eeschema executable. Can you follow this path, from eeschema until op184.lib is found?

O.k., just an overlap of posts. You may consider opening a bug report at Issues · KiCad / KiCad Source Code / kicad · GitLab.
