As a maintainer of devel/py-numba, could you have a look at PR #252648:
In short, TBB version 2021 will soon be available as devel/onetbb but the port you maintain does not build correctly with it, see the following Poudriere run:
and error logs:
numba/np/ufunc/tbbpool.cpp:40:13: error: no type named 'task_scheduler_init' in namespace 'tbb'; did you mean 'task_scheduler_handle'?
static tbb::task_scheduler_init *tsi = NULL;
[... and other errors ...]
Could you try to provide a patch (important: *by replying to this PR*) to facilitate the migration to devel/onetbb ?
To help you modifying your port, expected patches to devel/tbb and devel/onetbb are available in PR #252648.
You will also need suitesparse patches from PR #252651 as suitesparse does not build with oneTbb.
Thanks for your contribution,
Thanks David, Yuri! I can close that PR now :)
