The Addr2line tool (which is part of the standard GNU Binutils) is a tool that converts the instruction address and executable image into a file name, function name, and number of lines of source code. This feature is great for converting tracking addresses into more meaningful content.

To understand how this process works, we can test a simple interactive example. (I operate directly from shell, because this is the easiest way to demonstrate this process, as shown in Listing 4 .) In this example, the C file (test. c) usescatImplemented by a simple application (that is, the standard output text is redirected to a file ). Then use gcc to compile the file. It will pass some special options. First, you must-WlOption) notifies the linker to generate an image file and-gOption) notifies the compiler to generate debugging symbols. Generate an executable fileTest. After obtaining a new executable application, you can usegrepFind the tool in the Image FilemainTo find its address. Use this address and the Addr2line tool to determine the function name (main), The source file (/home/mtj/test. c), and its row number in the source file (4 ).

Use the Addr2line Tool-eOption to specify whether the executable image istest. Use-fIndicates the name of the output function.
