Describe the bug
Clicking "Bake" in any FLIP fluid domain yields the error Cannot find fluid engine libraries:, missing the .dlls:
- <libblpyfluiddebug.dll>
- <libblpyfluidrelease.dll>
To Reproduce
Provide descriptive instructions for how to reproduce the issue or how to use your .blend file.
FLIP Fluids cloned from master (rev) and built with Python 3.9.12, make 4.2.1, cmake 3.16.3.
Toy blend file.
Just click "Bake" in the FLIP Fluid Simulation physics properties on Cube.001.
Expected Behaviour
There is no error, the simulation bakes.
Actual Behaviour
A description of what actually happened.
Cannot find fluid engine libraries: <libblpyfluiddebug.dll> <libblpyfluidrelease.dll>. See system console for error info.

Hi, it looks like the addon has not been completely compiled. The fluid engine libraries are generated after compiling the program and should be located at build\bl_flip_fluids\flip_fluids_addon\pyfluid\lib\libblpyfluidrelease.dll and build\bl_flip_fluids\flip_fluids_addon\pyfluid\lib\libblpyfluiddebug.dll.
Please note that this issue tracker is only meant for issues/bugs related to the marketplace version of the FLIP Fluids addon. We are also unable to provide support for building and diagnosing issues related to building the addon on the wide range of systems, system setups, and builder experience.
Build/compile instructions can be found here: https://github.com/rlguy/Blender-FLIP-Fluids#building
If you are looking for a more detailed process building the addon on Windows, this is a good post by HDRMaps: https://hdrmaps.com/compiling-flip-fluids-add-on-on-windows/
We also have a free demo version of the addon that is pre-compiled here: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/FLIP-Fluids-Demo-Addon
been trying to fix the same issue for the past 40 minutes.... any updates or do i need to sell a kidney for the market version?
Hi @BlackPaw21, feel free to add me on Discord at shortcut5449 and I can help you get it running.
As Ryan mentioned, this is not actually an issue- it is just caused by trying to build the addon for Windows, from Linux.
