Hello, My team is running into an issue when trying to utilize the CtrlPort Monitor or Performance Monitor in our flowgraph. This issue arose after updating GNURadio to 3.11.
1. We are running GNURadio 3.11, installed from source, on Ubuntu 20.04.3 LTS. The CPU is a i7-7700. After some initial debugging, we noticed that Apache Thrift was closely tied to the Control Port, and we are running Thrift 0.13. 2. The errors arise when the CtrlPort Monitor or Performance Monitor are enabled, and I run any simple flowgraph where CtrlPort Monitor or Performance monitor are enabled. Initially, we received an invalid pointer error shown in the error message here: https://drive.google.com/file/d/1mITUMdVtjpcci6kZYyT2O2Q6RMy0WSa1/view?usp=sharing But after commenting out the block of code in the ctrl denoted by the red arrow 1, the invalid pointer error goes away. The snippet is from: gnuradio/gnuradio-runtime/python/gnuradio/ctrlport/monitory.py https://drive.google.com/file/d/1FhAF9lnnXuOmgmURuQ-FDLPPFK_xDfj7/view?usp=sharing However, we are now prompted with "Initiate try" followed by the error thrown in arrow 2 under the exception in the above screenshot. 3. We have tried uninstalling and reinstalling GNURadio on two separate machines (with identical specifications) and continue to run into the same issue. We have also reinstalled Thrift, but the issue still hasn't been resolved. 4. There is a relatively small amount of related issues found in our research, but there are a few issues such as #292, #2739 (further thrift investigation), and #3673 (the seemingly closest related issue) on the GNURadio GitHub (links below). However, they involve older versions of GNURadio and do not help with 3.11. Any help would be greatly appreciated! Thank you so much!
