gdlv core <executable> <core> panics immediately upon start with an "empty display string" panic:

gdlv core ./hello core
panic: empty display string

This doesn't have anything to do with core files. How are you running this? It can't connect to X11.

rakyll commented 7 years ago

Correct, gdlv panics regardless of the subcommand due to the missing desktop environment. I am not sure if you can do anything to detect the case that desktop env is missing and die with a friendlier error. Closing this issue.

aarzilli commented 7 years ago

Yes, a friendlier error message would be appropriate.
