Since C and C++ are so closely related, many features of GDB apply to both languages. Whenever this is the case, we discuss those languages together.
The C++ debugging facilities are jointly implemented by the C++
compiler and GDB. Therefore, to debug your C++ code
effectively, you must compile your C++ programs with a supported
C++ compiler, such as gnu g++
, or the HP ANSI C++
compiler (aCC
).
For best results when using gnu C++, use the stabs debugging
format. You can select that format explicitly with the g++
command-line options -gstabs or -gstabs+. See
Options for Debugging Your Program or gnu CC (Using gnu CC), for more information.
