Hi!

Trying to start remote debug.

Host: Debian 10, x86_64, g++ 4.8, -m32 key for compiler.
Remote pc: Debian 6.0.10, i686, gdbserver 7.0.1 (i486-linux-gnu).

Can anybody explain how to fix this? Thank you!

Error when starting to debug process:
This GDB was configured as "x86_64-linux-gnu".

- First you can debug fine without the symbols for these shared libraries.
- The errors may be ignored.
- It can be convenient to have the symbols available.

- Sometimes a Linux distro will provide a separate RPM (or equivalent) that installs the symbols for these libraries as separate files.
- You might want to contact a forum for your Linux distro.
- Otherwise you may need to rebuild these libraries and enable symbols to be built into the libraries.
