The command addr2line
is a utility in Linux for converting memory addresses into source code file names and line numbers. It is primarily used for debugging purposes.
The provided command addr2line --exe=${path-to-executable} --functions --demangle ${address}
has the following components:
addr2line
: The command itself, used to invoke theaddr2line
utility.--exe=${path-to-executable}
: This option specifies the path to the executable file for which you want to retrieve source code information.--functions
: This option tellsaddr2line
to output the names of the function(s) associated with the given address(es).--demangle
: This option instructsaddr2line
to demangle function names if they are mangled (e.g., from C++ names).${address}
: This parameter represents the memory address(es) for which you want to obtain the corresponding source code information.
When you run this command, addr2line
will analyze the given executable file (${path-to-executable}
) and map the provided memory address(es) (${address}
) to the corresponding function names and source code file locations. The output will show the source code file names and line numbers associated with the given address(es), as well as the demangled function names if applicable. This can help you determine the source code location that corresponds to a particular memory address, aiding in the debugging process.
