I help with packaging gnuradio in pkgsrc. We have 3.10.12.0 which
seems to be the latest, even though it's from February 2025.
Sometime after December 2025, the gnuradio-digital package started
having build errors - except perhaps on aarch64.
The problem is a compiler objection to casting pointers:
cannot convert from pointer to base class 'gr::basic_block' to pointer to derived class 'gr::digital::ofdm_carrier_allocator_cvc' via virtual base 'gr::tagged_stream_block'
I have pybind11 3.0.2 installed. After downgrading to 3.0.1, it builds
ok. (I am not running it; this is just building.)
I wonder:
- is 3.10.12.0 really the latest release?
- might this be fixed already?
- is anyone else running into this?
