The LDD and NM described in this article are two useful tools for analyzing programs under Linux. LDD is a tool used to analyze the dynamic libraries that a program needs to rely on when it runs; nm is a tool for viewing the contents of a symbol table in a specified program. Here are some examples of these two tools:1. LDD, look at the following example, using LDD to see the dynamic library on which CS prog

NM command[In the content provided by the gnu c language library, an interface can be used to do this. Run the following command to View Details:Nm-D/lib/libc. so.6 | grep log] The nm command is relatively simple and powerful. It is used to list various symbols in a target file. There are many types of symbols. The following are some common symbol types.

The nm command can list the symbol tables in a function library file. It works for both static function libraries and shared function libraries. For a given function library, the NM command can list all the symbols defined in the function library, including the values and types of each symbol. You can also define the number of rows of the function (Symbol) in the original program. However, this requires tha

Excerpted from http://blog.csdn.net/solmyr_biti/article/details/6565479The NM command introduces many, but mostly does not describe the meaning of its function symbol flags.Most recently used in debugging a dynamic library, which uses the most:Nm-a * |grep "AAA" | C++filt//-A in order to display the file, C++filt converted to a readable style, as if there is a parameter to achieve similar functionsOther content is organized as follows (unknown to the

through nm To debug a function, you need to set a breakpoint. to ensure that the function does not repeat the symbols in the c library, add the unified prefix zif before the function is exported, to know that the breakpoint is to be debugged. which symbols are available for so? the nm command is no longer suitable. The nm command is used to list the symbols of t
