Display the call stack from a C++ program like Python.

To retrieve the source code from your executable, the module uses under: * Linux, the library "libbfd" (gcc flag -rdynamic must be active) * Windows, the library "Dbghelp.lib"

Of course the code must be compiled with -g or equivalent to produce debugging information.

For example, under linux, if your program throws an exception, your program will display:

Traceback (most recent call last) File "/projects/traceback/main.cpp", line 18 main File "/projects/traceback/main.cpp", line 13 foo(int) File "/projects/traceback/main.cpp", line 11 foo(int) File "/projects/traceback/exception.hpp", line 120 traceback::Exception<std::runtime_error>::Exception(std::string const&) File "/projects/traceback/exception.hpp", line 69 traceback::ErrorInfo::ErrorInfo(std::exception*, char const* (std::exception::*)() const) ErrorInfo: An error message: [Errno 2] No such file or directory

Under Windows, your program will display: Traceback (most recent call last) File "c:\projects\traceback\main.cpp", line 18 main File "c:\projects\traceback\main.cpp", line 13 foo File "c:\projects\traceback\main.cpp", line 11 foo File "c:\projects\traceback\exception.hpp", line 120 traceback::Exception<std::runtime_error>::Exception<std::runtime_error> File "c:\projects\traceback\exception.hpp", line 69 traceback::ErrorInfo::ErrorInfo ErrorInfo: An error message: [Errno 2] No such file or directory

The code is based on the source code "addr2line" from the binutils library and from the msdn documentation.

To compile the test program, under Linux, you must run the following commands: g++ -g -c -rdynamic -Wall -Wextra traceback.cpp g++ -g -c -rdynamic -Wall -Wextra main.cpp g++ -rdynamic -g -Wall -Wextra -o test traceback.o main.o -lbfd ./test

Under windows: cl /Od /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /Gm /EHsc /RTC1 /MDd /c /ZI /TP exception.cpp cl /Od /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /Gm /EHsc /RTC1 /MDd /c /ZI /TP main.cpp link /DEBUG exception.obj main.obj Dbghelp.lib /out:test.exe test
