'How do I access the `addr2line` functionality within my C++ program?
I need to get the information provided by addr2line (source file and line from backtracing a function call) from within a C++ program.
I know I can call addr2line directly as a subprocess and I know that I can copy the source code of addr2line into my program (which is also GPL licensed). But the code looks complicated and I don't feel comfortable using it directly. What does bfd mean, anyway? I would prefer to use some function in the C++ STL library, because that would be cleaner.
I am working in a Linux environment.
Solution 1:[1]
You can try the function dladdr(). It uses the dynamic symbols of the program, not the debugging information (compile the program with gcc -rdynamic).
Also, you can check the backtrace library, or the higher level stacktrace library.
Not exactly what you are asking, but they may prove useful.
Solution 2:[2]
Check the source code of bsd implementation of addr2line, it has only about 400 lines code. Change the source to a library function should be very easy. http://sourceforge.net/p/elftoolchain/code/HEAD/tree/trunk/addr2line/addr2line.c
