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.

View source code from a "Symbols Server" without debugging?

I know it's possible to publish our source/symbols to a symbol server, or use something like SymbolSource.org to allow us to step into the code when we are referencing a DLL. But I have found no way to access this same code when we are not in a…

Can you retrieve source from a debug-compiled binary?

I was digging around and found an executable for something I wrote in Visual C++ 6.0 about 8 years ago. I never backed up the source code, but I think I always compiled everything in debug mode. I also vaguely remember hearing somewhere that "you…
