Questions tagged [debug-symbols]

A debug symbol is information that expresses which programming-language constructs generated a specific piece of machine code in a given executable module.

A debug symbol is information that expresses which programming-language constructs generated a specific piece of machine code in a given executable module. Sometimes the symbolic information is compiled together with the module's binary file, or distributed in a separate file, or simply discarded during the compilation and/or linking. This information enables a person using a symbolic debugger to gain additional information about the binary, such as the names of variables and routines from the original source code. This information can be extremely helpful while trying to investigate and fix a crashing application or any other fault.

How can I debug multiple apps by loading multiple symbol definitions with GDB?

Make gdb search for symbol files again

My distribution (Debian) ships debug files in separate packages. So what happens often is that I run a program in gdb until it crashes, in order to obtain a usable backtrace for a bug report. But bt is rather useless, missing the symbol information…
