vtable-dumper's Introduction

NAME:
  Vtable-Dumper - a tool to list content of virtual tables in a C++ shared library
  
  It is intended for developers of software libraries and maintainers of Linux
  distributions who are interested in ensuring backward binary compatibility.

INSTALL:
  sudo make install prefix=/usr
  
REQUIRES:
  libelf
  libdl
  libstdc++

USAGE:
  vtable-dumper SHLIB
  
EXAMPLE:
  vtable-dumper /usr/lib64/libstdc++.so.6

OPTIONS:
  -mangled       Show mangled symbol names
  -demangled     Show de-mangled symbol names
  -help          Display this help message
  -dumpversion   Print the tool version and don't do anything else
  
NOTE:
  Make sure that all dependencies of a target library can be found by ldd. Otherwise
  dlopen() may fail. Add paths to these libraries to LD_LIBRARY_PATH in this case.
