- How do I print the elements of a C++ vector in GDB?
$1 = std::vector of length 3, capacity 4 = {10, 20, 30} To achieve above, you need to have gdb 7 (I tested it on gdb 7 01) and some python pretty-printer Installation process of these is described on gdb wiki What is more, after installing above, this works well with Eclipse C++ debugger GUI (and any other IDE using GDB, as I think)

Printing type of variable: ptype <VARIABLE_SYMBOL> For class objects, prints the signature of the whole class Printing a vector: p[rint] <VECTOR> Printing an element in a vector: Often operator[] or at() method don’t work in gdb Instead, use <VECTOR> _M_impl _M_start+<INDEX> This will return the pointer to the target element in the underlying array, so dereferencing the pointer would give

When you try to use GDB's "print" command to display the contents of a vector, a stack, or any other GDB abstract data structure, you will get useless results Instead, download and install one of following tools to properly view the contents of STL containers from within GDB GDB 7 0 will include support for writing pretty-printers in Python

Let’s see what happens when a GDB Python Pretty Printer is installed and GDB calls this printer to assemble the output: (gdb) print vec \$1 = std::vector of length 4, capacity 4 = {7, 5, 16, 8} That's a far more useful view of the data and contains the actual content of the vector That pretty printer, used in this example, exists today

Since we selected the “array” display hint, this will automatically reflect preferences for printing arrays (as set by set print array) The printer we’ve built will automatically walk a list of arbitrary length; with the full power of Python available, combined with GDB’s access to data values and types, it is possible to decode
