Can Nsight Systems use debug info URLs?

So I am on Arch Linux and the libraries from the official repositories do not ship with debug symbols. To work around this in most debugging tools, one can use DEBUGINFOD_URLS=https://debuginfod.archlinux.org as an environment variable (e.g. DEBUGINFOD_URLS=https://debuginfod.archlinux.org valgrind ./myApp). I tried adding that environment variable both before launching nsys-ui and in the "Environment variables" section of "Collect CPU IP/backtrace samples", but both do not seem to add any debug symbols for system libraries.

Therefore I end up with loads of unresolved symbols as can be seen in the "Top-Down View". unresolved symbols

As can be seen here there is a "Symbol locations..." option but that only allows adding local paths. "Symbol locations..." option

Is it possible to add the debug symbols via a debug info URL in Nsight Systems?

Specs: Nsight Systems 2022.4.2

Solution

  • Specifically for Linux, it is not currently possible to resolve symbols from symbol servers.

    Answering the question more broadly, symbol resolution from servers is available for Windows. You can also refer to Symbol Resolution at the Nsight Systems Documentation for more information.
