C and C++

Since C and C++ are so closely related, many features of GDB apply to both languages. Whenever this is the case, we discuss both languages together.

The C++ debugging facilities are jointly implemented by the GNU C++ compiler and GDB. Therefore, to debug your C++ code effectively, you must compile your C++ programs with the GNU C++ compiler, g++.

For best results when debugging C++ programs, use the stabs debugging format. You can select that format explicitly with the g++ command-line options `-gstabs' or `-gstabs+'. See section 'Options for Debugging Your Program or GNU CC' in Using GNU CC, for more information.
