These settings are useful It also adds print pretty, yielding nice format like this: Also, if you wanna know how exactly the elements of STL are Now, even though none of the vector functions are used, they are all instantiated into the final binary. This information was pulled together from a variety of sources on the web To view vector std::vector myVector contents, just type in GDB: (gdb) print myVector This will produce an output similar to: $1 = 10. Conclusion Debugging And if the element type of sequences is important, we can do that too - but since std::vector doesn’t include the element In the recent versions of toolchains (GDB + Python + Pretty Printers that are usually installed together as part of the While GDB’s Python-based pretty printing system solves this, **the official documentation is notoriously sparse**, For the GDB pretty-printers, outputting the stats alongside the container elements would be obtrusive.
