Description Petr Viktorin 2019-06-19 15:30:15 UTC

In a recent gdb update,  "Missing separate debuginfos"  messages started appearing on stderr, rather than on stdout as in previous versions.

Fedora 30:

$ rpm -q gdb
gdb-8.3-3.fc30.x86_64
$ echo 'run' | gdb --args python3 > /dev/null
$

Fedora Rawhide:

$ rpm -q gdb
gdb-8.3.50.20190610-16.fc31.x86_64
$ echo 'run' | gdb --args python3 > /dev/null

warning: Unable to open "librpm.so.8" (librpm.so.8: cannot open shared object file: No such file or directory), missing debuginfos notifications will not be displayed

I could not find this mentioned in any changelog, so I'd like to ask:

- Is this change intended/reasonable? (If so, I'll need to update Python's tests, which verify Python-GDB integration by examining output)
- Is there a way to point stdlog back at stdout?

Comment 1 Sergio Durigan Junior 2019-06-21 19:26:43 UTC

GDB needed to be rebuilt to use the new librpm.so.9.  gdb-8.3.50.20190610-17.fc31 should fix this problem.  Please reopen the bug if you still see the issue.  Thanks.
