same way I debug everything, everywhere: logging.

That not very environmentally friendly.

I just got comfortable using gdb/lldb from the terminal. Once you get used to it, it's fine (albeit not pretty).

The advantage for text based interfaces is that they work over ssh/tmate over trans atlantic connections whereas the GUI tools would suffer greatly. It just works everywhere and if you learn it, it will be just as good as a gui debugger. Potentially even more ergonomic without hunting for options with a mouse.

I‘m using cgdb, which is a minimal ncurses wrapper around gdb. It‘s a lot better than the TUI of gdb.

Termdebug works great with gdb, and I get my usual editor features as well as the full functionality of gdb. Seems fine to me.

Before I switched from emacs I had an equivalently good setup with dap-mode.

Use Emacs to drive gdb (through the GUD mode) gives a much more ergonomic interface. It highlights the line of code being traced in the code window.

as I said - this easy to fix once and for ever

Also not all apps write to stdout/stderr by default.

It depends on what comfortable is for you. Most of my pc experience is terminal and browser and this is comfortable for me. I just use gdb for debugging. Sometimes trying lldb

emacs. Worked great for decades and works great today. Learn it.
