10 months ago libasn lib is a library (currently private) for decoding RRC layer messages (It will decode SIBs in the context of NG-Scope). This library is not essential for NG-Scope and it will work perfectly without it.
Have you tried with another USRP model (e.g. B210)?

9 months ago Hi Jon, I also tried USRP N210, but it still doesn't work :(

9 months ago I've figured it out that the system crashes when it's in Ubuntu20.04, and it works well in Ubuntu16. Maybe more testing is required for Ubuntu20.04
Issue Description
With the latest NG-Scope built and all test cases passed, there's a runtime exception saying there's no received samples from UHD. Therefore, the PBCH channel of the detected cell cannot be decoded. The exception error is as follows:

Setup Details
I'm using USRP X310, and measure multiple bands from both T-Mobile and Verizon cells nearby. The OS is ubuntu20.04, and all required dependent packages from the Wiki are installed. However, the "cmake ../" shows that I haven't installed the libasn4g(basically libasn4g.so cannot be found). Do you think this matters?
Expected Behavior
There shoud be at least some samples from the UHD, since the UHD runtime is constructed.
Actual Behaviour
Timeout when receiving any sample
Additional Information
I've attached the config file and complete error log for your reference. Really appreciate it if you can help to check it!
