5 months ago 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.

5 months ago @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.

5 months ago 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.

5 months ago 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.

5 months ago I was able to build with the above patch (applied to the fluent-bit recipe) and also by setting the number of parallel processes to 1, because there was an issue with luajit compiling dependencies after they were needed. I will look into creating a PR
