Got the following problem:

The function kt_thr_pool_init() references
the function __init kt_cache_init().
This is often because kt_thr_pool_init lacks a __init 
annotation or the annotation of kt_cache_init is wrong.

Hi,

You have to apply this patch to GCC, as described here.

Let me know if it doesn't help, closing the issue for now.
