I do not recommend mixing repositories like that. Sometimes this could work but 
usually this cause various problems. You could either build gnuradio from 
source, upgrade Debian to bookworm or work in a container/VM.

You have two gnuradio versions installed in parallel - 
/lib/libgnuradio-runtime.so.3.8.5 and 
/usr/local/lib/libgnuradio-runtime.so.3.10.3. The version in /lib is probably 
installed from package and the version in /usr/local/lib is probably installed 
from source, debian packages never put files in /usr/local/

Having two versions like this could cause various hard to debug problems so my 
advice is first to clean up your system, uninstall all gnuradio versions, 
manually check and remove all gnuradio's files in /usr and /usr/local (find 
/usr -name "*gnuradio*) and then install only one version.

You can use pybombs (I do not recommend this) to install multiple gnuradio 
versions in different prefixes but if you choose this method do not install 
gnuradio's packages from the apt repository and do not use /usr/ or /usr/local 
as prefix (install system wide).

Dear all!

I am working on enabling gnuradio to run faster on the browser through `simd on 
wasm`.
I will post weekly updates in this thread(sorry there lost 2 weeks’ logs). The 
following is from last week:

Short version:
Have uploaded a wiki page to try to grab the basic gnuradio-web workflow and 
the main method in accelerate gnuradio-web

I will post weekly updates in this thread. The following is from last week:

Short version report:
Later plan:

1. Develop those missing components in gr-web (making it more extensible)

2. To support `simd on wasm` this project will go slow pace.

Hi, everyone!

I am working on enabling gnuradio to run faster on the browser through `simd on 
wasm`.
I will post weekly updates in this thread. The following is from last week:

Short version report:
Has Done:
   1. Building debug mode `CPython`.
2. Compare the `webapp` directory output files. (not fully finish)
3. Use `wasm2wat` to ensure `volk` is really under `wasm-simd`.

Delay and TODO in this week:
2. Compare the `webapp` directory output files.
4. Enabling open and save files for user-selected paths in gr-web.
