Do you need "set solib-search-path" or "set sysroot"?

Thread::Backtrace::Location

The Location class is used by Kernel#caller_locations to store information of every call frame in a call stack. Instances of this class can store information such as:

  • The path to the file where the frame originated from
  • The name of the context of the frame (method name, "block", etc)
  • The line number where the frame originated from
