Hi @sv1bds ,

Thanks for opening this issue.

I have to add: sudo apt-get install libsndfile1-dev

That's right, you need to install libsndfile1-dev. That's actually a problem with the gnuradio-dev package, which I think should include libsndfile1-dev as a dependency to enable OOTs depending on gr-blocks.

If you are unsure about what to install, you can follow the Docker image recipe at: https://github.com/igorauad/gr-dvbs2rx/blob/master/Dockerfile. You can replicate the steps there on a fresh Ubuntu installation.

AssertionError: Lists differ: [(-1+0j), (3+0j), (-2+0j), (2+0j), (-2.5+0j), (1.5+0j)] != [(-1+0j), (3+0j), (-2+0j), (2+0j), (-2.5+0j)]

Regarding this error on qa_plsync_cc, you are right, it does show up on Ubuntu 22.04. I was able to reproduce it. I investigated and concluded the problem was due to a change on scipy.signal.upfirdn, a function from SciPy used on this particular test case. Ubuntu 22.04 has a more recent version of SciPy (1.8), which includes the referred behavioral change and broke the test. I've pushed a fix to the master branch (commit cec3540).

Let me know if you have more questions.

Would be nice to add sudo apt-get install libsndfile1-dev to the install instructions, since the latest GR off the PPA doesn't include it, so most folks wont have it.

Hi, @777arc. Thanks for the suggestion. The installation instructions now mention libsndfile1-dev and the other build dependencies.

I'm going to close this issue for now. Please feel free to reopen or create another one.
