Hi,

Double-posting is a bit discouraged. Please try to avoid that
https://github.com/thom311/libnl/issues/143 . Thanks.

Anyway, the mailing list is indeed a more suitable place for asking
such a question.


I just quote myself:

====
NLE_OBJ_NOTFOUND is likely the response from kernel to a request you
make. I would run the application with strace to see which syscall
fails.

Alternatively, set NLDBG=100 environment variable and see if it reveals
useful info.

Alternatively, use a debugger and singlestep through the program.

Alternatively, build libnl from source and add additional debug logging
(printf-debugging)

Best,
Thomas
