BitBake compilation with Lua scripting support failing about fluent-bit HOT 5 OPEN

I think that is for the luajit project though so it would need patching there if we wanted to import it but hopefully gives @lizziemac some info. A docs PR on it would be good too if it works: https://github.com/fluent/fluent-bit-docs/blob/master/installation/yocto-embedded-linux.md

Be good to update the minimum version there as well.

Yes, I don't think LUA is supported due to some additional requirements.
Yocto/Bitbake is currently best effort support - we can't test it in CI at the moment to verify anything or officially release it.

@tarruda may be able to help with the specific requirements of building LUA but my understanding is it was not possible on Bitbake at the time it was last tried. If it is then feel free to submit a PR.

In the file:
lib/luajit-cmake/host/minilua/CMakeLists.txt

There is an if to add LIBM:

find_library(LIBM_LIBRARIES NAMES m)
...
if(LIBM_LIBRARIES)
  target_link_libraries(minilua ${LIBM_LIBRARIES})
endif()

But it does not fail if it can't find LIBM_LIBRARIES (find_library(LIBM_LIBRARIES NAMES m))

I tried to inherit pkg-config in the recipe but it still couldn't find it.

LIBM is a very primitive library, so I tried to force the linking

- if(LIBM_LIBRARIES)
-  target_link_libraries(minilua ${LIBM_LIBRARIES})
-endif()
+ target_link_libraries(minilua libm.so)

And it worked for me.
