To debug a stripped binary when GDB reports no debugging symbols found, you need to locate separate debug files or use debuginfod to resolve symbols remotely. This involves checking for split DWARF files to restore missing debug information.

To inspect DWARF debug sections in an ELF binary, use tools like dwarfdump, llvm-dwarfdump, or readelf. These tools allow you to examine sections like .debug_info and .debug_line to understand debug information structure.

Split DWARF is a format that separates debug information into .dwo files, optimizing debug symbol delivery by keeping the main ELF binary small. You can use the dwp tool to package these files and debuginfod to resolve them remotely.

Link-Time Optimization (LTO) can cause symbol resolution failures by altering the binary structure, which complicates debug information mapping. You can diagnose these LTO and symbol stripping issues by inspecting DWARF sections with dwarfdump.

Yes, you can use debuginfod to fetch debug symbols for a stripped binary by querying remote symbol servers. This resolves missing symbols by downloading the required DWARF debug information on demand during your debugging session.
