I compiled Blender as python module successfully in Windows Platform. I can now import bpy without problems from my script. Now I would like use an add-on from my script but I receive this error:

AttributeError: Calling operator "bpy.ops.importgis.georaster" error, could not be found.

Obviously, because I haven't compiled this add-on. How do I compile it?

I solved this by enabling addon: bpy.ops.wm.addon_enable(module="BlenderGIS-master")

    $\begingroup$ I compiled it with CMake in Windows 10 following this example: cobertos.com/… $\endgroup$

  • $\begingroup$ It's not that the addon isn't compiled, it isn't enabled. Can enable addon in script using from addon_utils import enable and enable("BlenderGIS") .. could be a bit dodgy with this addon by the looks. Also checkout the code, may find a direct method via reading code, and using from BlenderGIS import ... making it possible to bypass using operator altogether. (eg see if operator just sets parameters and calls a function, and use that funciton) $\endgroup$

  • $\begingroup$ Nice, wasn't sure if window manager ops would work for bpy as py module. $\endgroup$

About the title of the question: you cannot compile add-ons because they are written in Python*.

Your script causes this error because it wasn't registered with Blender. Use the normal way (i.e. the regular Blender UI) to enable your add-on, and be sure to save your preferences so that it stays enabled. Once that's done it should simply work, also with Blender compiled as a module.

(*) Little footnote: Python is compiled into bytecode, but by the Python runtime itself, and doesn't require any action from the user contrary to "compiled languages" like Go or C.

  • $\begingroup$ I would avoid the normal blender installation, because I only need the module for my custom script. Anyway I will try as your suggestion and I will let you know. Thank you so much $\endgroup$

  • $\begingroup$ You don't need a normal Blender installation, you just need to have your addon activated. The easiest way to do that in general is with the regular Blender UI, but @batFINGER also described another approach. $\endgroup$
