Flecs for Embedded - is it possible?

[Myonmu]

I have tried to run Flecs on embedded devices (e.g. Playdate) but currently encountered the os api related issues.

I can probably write the dedicated os api for the device, but here's the issue... I see that flecs expects the os to have multi-threading abilities, but Playdate doesn't have that. Does that mean it is completely impossible to port Flecs to run on embedded (regardless of how performant it could be), or adjustments could be made so that multi-threading would be optional?

As far as I remember, Flecs runs single-threaded by default.

Have you tried just leaving the thread related OS API functions unset?

Have you tried looking into defines such as FLECS_CUSTOM_BUILD (or FLECS_NO_OS_API_IMPL)?
I'm not super familiar with customizing Flecs myself, and so I'm not sure what you mean by "use" the headers.

yes, I added them, it compiles and builds but on the device it crashes (can't load the dll). I suspect that even <stdio.h> is not allowed and tried to comment out all of them, but the codebase seems to pretty much assume having an OS... Not having much luck so far

If the code builds then it's not related to stdio.h. Can you post the logs with which it's failing on device? Sounds like either an issue with finding the DLL, or resolving a symbol (in which case the logs should indicate which one).

[Myonmu]

it's an LoadLibraryA() failure with error code 126, and after inspecting the dependencies the dll expects flecs.dll despite having FLECS_STATIC. It seems that both SHARED and STATIC are cached ON, set SHARED to OFF seems to solve the problem.
